This year the NYC Department of Transportation closed 20 miles of streets across the 5 boroughs and opened them to cyclists, joggers, skate boarders and walkers.

 

Summer Streets takes place on consecutive Saturdays in the summer (the 2011 dates are August 6, 13 and 20) from 7:00 am - 1:00 pm. The 2010 route connects the Brooklyn Bridge with Central Park with recommended connections along low-traffic streets to the Hudson River Greenway, Harlem and Governors Island allowing participants to plan a route as long or short as they wish.

 

This event takes a valuable public space - our City's streets - and opens them up to people to play, walk, bike, and breathe. Summer Streets provides more space for healthy recreation and is a part of NYC's greening initiative by encouraging New Yorkers to use more sustainable forms of transportation.

 

Modeled on other events from around the world including Bogotá, Colombia's Ciclovia, Paris, France's Paris Plage, and even New York's own Museum Mile, this event will be part bike tour, part block party, a great time for exercise, people watching, and just enjoying summer mornings.

NYC DEPT OF TRANSPORTATION ASPHALT PLANT

Broadway is a road in the U.S. state of New York. Broadway runs from State Street at Bowling Green for 13 mi through the borough of Manhattan and 2 mi through the Bronx, exiting north from New York City to run an additional 18 mi through the Westchester County municipalities of Yonkers, Hastings-On-Hudson, Dobbs Ferry, Irvington, and Tarrytown, and terminating north of Sleepy Hollow.

It is the oldest north–south main thoroughfare in New York City, with much of the current street beginning as the Wickquasgeck trail before the arrival of Europeans. This formed the basis for one of the primary thoroughfares of the Dutch New Amsterdam colony, which continued under British rule, although most of it did not bear its current name until the late 19th century.

Broadway in Manhattan is known widely as the heart of the American commercial theatrical industry, and is used as a metonym for it, as well as in the names of alternative theatrical ventures such as Off-Broadway and Off-off-Broadway.

Broadway was originally the Wickquasgeck trail, carved into the brush of Manhattan by its Native American inhabitants. This trail originally snaked through swamps and rocks along the length of Manhattan Island.

Upon the arrival of the Dutch, the trail was widened and soon became the main road through the island from Nieuw Amsterdam at the southern tip. The Dutch explorer and entrepreneur David Pietersz. de Vries gives the first mention of it in his journal for the year 1642 ("the Wickquasgeck Road over which the Indians passed daily"). The Dutch called it the Heeren Wegh or Heeren Straat, meaning "Gentlemen's Way" or "Gentlemen's Street" – echoing the name of a similar street in Amsterdam – or "High Street" or "the Highway"; it was renamed "Broadway" after the British took over the city, because of its unusual width. Although currently the name of the street is simply "Broadway", in a 1776 map of New York City, it is labeled as "Broadway Street".

In the 18th century, Broadway ended at the town commons north of Wall Street. The part of Broadway in what is now lower Manhattan was known as Great George Street. Traffic continued up the East Side of the island via Eastern Post Road and the West Side via Bloomingdale Road. The latter, which opened in 1703, continued up to 117th Street and contributed to the development of the modern Upper West Side into an upscale area with mansions.

In her 1832 book Domestic Manners of the Americans, Fanny Trollope wrote of her impressions of New York City in general and of Broadway in particular:

This noble street may vie with any I ever saw, for its length and breadth, its handsome shops, neat awnings, excellent trottoir, and well-dressed pedestrians. It has not the crowded glitter of Bond Street equipages, nor the gorgeous fronted palaces of Regent Street; but it is magnificent in its extent, and ornamented by several handsome buildings, some of them surrounded by grass and trees.

In 1868, Bloomingdale Road between 59th Street (at the Grand Circle, now Columbus Circle) and 155th Streets would be paved and widened, becoming an avenue with landscaped medians. It was called "Western Boulevard" or "The Boulevard". An 1897 official map of the city shows a segment of what is now Broadway as "Kingsbridge Road" in the vicinity of Washington Heights.

On February 14, 1899, the name "Broadway" was extended to the entire Broadway / Bloomingdale / Boulevard / Kingsbridge complex.

In the 20th century, a 30-block stretch of Broadway, extending mainly between Times Square at 42nd Street and Sherman Square at 72nd Street, formed part of Manhattan's "Automobile Row". Before the first decade of the 20th century, the area was occupied mostly by equestrian industries and was "thoroughly lifeless", but by 1907, The New York Times characterized this section of Broadway as having "almost a solid line of motor vehicle signs all the way from Times Square to Sherman Square". In the late 1900s and early 1910s, several large automobile showrooms, stores, and garages were built on Broadway, including the U.S. Rubber Company Building at 58th Street, the B.F. Goodrich showroom at 1780 Broadway (between 58th and 57th Streets), the Fisk Building at 250 West 57th Street, and the Demarest and Peerless Buildings at 224 West 57th Street.

Broadway once was a two-way street for its entire length. The present status, in which it runs one-way southbound south of Columbus Circle (59th Street), came about in several stages. On June 6, 1954, Seventh Avenue became southbound and Eighth Avenue became northbound south of Broadway. None of Broadway became one-way, but the increased southbound traffic between Columbus Circle (Eighth Avenue) and Times Square (Seventh Avenue) caused the city to re-stripe that section of Broadway for four southbound and two northbound lanes. Broadway became one-way from Columbus Circle south to Herald Square (34th Street) on March 10, 1957, in conjunction with Sixth Avenue becoming one-way from Herald Square north to 59th Street and Seventh Avenue becoming one-way from 59th Street south to Times Square (where it crosses Broadway). On June 3, 1962, Broadway became one-way south of Canal Street, with Trinity Place and Church Street carrying northbound traffic.

Another change was made on November 10, 1963, when Broadway became one-way southbound from Herald Square to Madison Square (23rd Street) and Union Square (14th Street) to Canal Street, and two routes – Sixth Avenue south of Herald Square and Centre Street, Lafayette Street, and Fourth Avenue south of Union Square – became one-way northbound. Finally, at the same time as Madison Avenue became one-way northbound and Fifth Avenue became one-way southbound, Broadway was made one-way southbound between Madison Square (where Fifth Avenue crosses) and Union Square on January 14, 1966, completing its conversion south of Columbus Circle.

In 2001, a one-block section of Broadway between 72nd Street and 73rd Street at Verdi Square was reconfigured. Its easternmost lanes, which formerly hosted northbound traffic, were turned into a public park when a new subway entrance for the 72nd Street station was built in the exact location of these lanes. Northbound traffic on Broadway is now channeled onto Amsterdam Avenue to 73rd Street, makes a left turn on the three-lane 73rd Street, and then a right turn on Broadway shortly afterward.

In August 2008, two traffic lanes from 42nd to 35th Streets were taken out of service and converted to public plazas. Additionally, bike lanes were added on Broadway from 42nd Street down to Union Square.

Since May 2009, the portions of Broadway through Duffy Square, Times Square, and Herald Square have been closed entirely to automobile traffic, except for cross traffic on the Streets and Avenues, as part of a traffic and pedestrianization experiment, with the pavement reserved exclusively for walkers, cyclists, and those lounging in temporary seating placed by the city. The city decided that the experiment was successful, and decided to make the change permanent in February 2010. Though the anticipated benefits to traffic flow were not as large as hoped, pedestrian injuries dropped dramatically and foot traffic increased in the designated areas; the project was popular with both residents and businesses. The current portions converted into pedestrian plazas are between West 47th Street and West 42nd Street within Times and Duffy Squares, and between West 35th Street and West 33rd Street in the Herald Square area. Additionally, portions of Broadway in the Madison Square and Union Square have been dramatically narrowed, allowing ample pedestrian plazas to exist along the side of the road.

In May 2010 somebody tried to set off a bomb on Broadway in Time Square. The bomb was in an illegally parked 4WD. Shopkeepers and others people notified a mounted police officer who then inspected the vehicle. The officer noticed that there was smoke and explosives. He immediately called for assistance and the street was evacuated.

In May 2013, the NYCDOT decided to redesign Broadway between 35th and 42nd Streets for the second time in five years, owing to poor connections between pedestrian plazas and decreased vehicular traffic. With the new redesign, the bike lane is now on the right side of the street; it was formerly on the left side adjacent to the pedestrian plazas, causing conflicts between pedestrian and bicycle traffic.

In spring 2017, as part of a capital reconstruction of Worth Square, Broadway between 24th and 25th Street was converted to a "shared street" where through vehicles are banned and delivery vehicles are restricted to 5 miles per hour. Delivery vehicles go northbound from Fifth Avenue to 25th Street for that one block, reversing the direction of traffic and preventing vehicles from going south on Broadway south of 25th Street. The capital project expands on a 2008 initiative where part of the intersection of Broadway and Fifth Avenue was repurposed into a public plaza, simplifying that intersection. As part of the 2017 project, Worth Square was expanded, converting the adjoining block of Broadway into a "shared street".

No, this is not Lance Armstrong’s bicycle. It is Alicja Kwade’s sculpture Journey without Arrival (Raleigh), part of the Public Arts Fund’s “Lightness of Being” exhibit in City Hall Park. “With familiar forms gone awry, her poetic works transform materials in ways that suggest time and space are malleable ideas,” says the artwork’s explanatory note, which adds “Please do not touch the work of art.”

 

I suppose this answers the question, “What is art?”

Art is being able to destroy a perfectly good bicycle

and charge more for it

after it has been made totally useless...

Vanderbilt Avenue in Manhattan runs from 42nd Street to 47th Street between Park Avenue and Madison Avenue. It was built in the late 1860s as the result of construction of Grand Central Depot. The southbound Park Avenue Viaduct around the Grand Central Terminal runs above the street's eastern side. The Yale Club of New York City is located on Vanderbilt Avenue, at the intersection of East 44th Street, as is the Manhattan Institute for Policy Research, and One Vanderbilt supertall skyscraper. When it was originally built, it ran from 42nd Street to 49th Street. However, in the 1960s, the portion between 47th Street and 49th Street was closed permanently, as it became part of 270 Park Avenue and 280 Park Avenue.

The Postcard

 

A postally unused postcard that was published prior to 1995 by Alfred Mainzer Inc. of Long Island City, N.Y. The card was printed in Thailand.

 

On the divided back of the card the publishers have printed:

 

'East River with Brooklyn Bridge

against a backdrop of the Twin

Towers of the World Trade Center

and the Woolworth Building, New

York City'.

 

NYC - The World Trade Center 1973 - 2001

 

The original World Trade Center was a large complex of seven buildings in the Financial District of Lower Manhattan, New York City. It opened on the 4th. April 1973, and was destroyed in 2001 during the September 11 attacks.

 

At the time of their completion, the Twin Towers—the original 1 World Trade Center (the North Tower), at 1,368 feet (417 m); and 2 World Trade Center (the South Tower), at 1,362 feet (415.1 m)—were the tallest buildings in the world.

 

Other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex contained 13,400,000 square feet (1,240,000 m2) of office space. That's a lot of floor space - 308 acres.

 

The core complex was built between 1966 and 1975, at a cost of $400 million (equivalent to $2.27 billion in 2018).

 

During its existence, the World Trade Center experienced several major incidents, including a fire on the 13th. February 1975, a bombing on the 26th. February 1993, and a bank robbery on the 14th. January 1998.

 

In 1998, the Port Authority of New York and New Jersey decided to privatize it by leasing the buildings to a private company to manage. It awarded the lease to Silverstein Properties in July 2001.

 

-- The 9 - 11 Attacks

 

On the morning of the 11th. September 2001, Al-Qaeda-affiliated hijackers flew two Boeing 767 jets into the Twin Towers within minutes of each other; two hours later, both towers collapsed. The attacks killed 2,606 people in the towers and their vicinity, as well as all 157 on board the two aircraft.

 

Falling debris from the towers, combined with fires that the debris initiated in several surrounding buildings, led to the partial or complete collapse of all the buildings in the complex, and caused catastrophic damage to ten other large structures in the surrounding area.

 

-- Subsequent Developments

 

The clean-up and recovery process at the World Trade Center site took eight months, during which the remains of the other buildings were demolished.

 

A new World Trade Center complex is being built (2020) with six new skyscrapers and several other buildings, many of which are complete. A memorial and museum to those killed in the attacks, a new rapid transit hub, and an elevated park have been opened.

 

One World Trade Center, the tallest building in the Western Hemisphere at 1,776 feet (541 m) and the lead building for the new complex, was completed in May 2013, and opened in November 2014.

 

During its existence prior to 2001, the World Trade Center was an icon of New York City. It had a major role in popular culture, and according to one count was depicted in 472 films. Following the World Trade Center's destruction, mentions of the complex were altered or deleted, and several dozen "memorial films" were created.

Economic Effects of the September 11 Attacks

 

The September 11 attacks in 2001 were followed by initial shocks causing global stock markets to drop sharply. The attacks themselves resulted in approximately $40 billion in insurance losses, making it one of the largest insured events ever.

 

-- Financial markets

 

On Tuesday, September 11, 2001, the opening of the New York Stock Exchange (NYSE) was delayed after the first plane crashed into the World Trade Center's North Tower, and trading for the day was canceled after the second plane crashed into the South Tower.

 

The NASDAQ also canceled trading. The New York Stock Exchange Building was then evacuated as well as nearly all banks and financial institutions on Wall Street and in many cities across the country.

 

The London Stock Exchange and other stock exchanges around the world were also closed down and evacuated in fear of follow-up terrorist attacks.

 

The New York Stock Exchange remained closed until the following Monday. This was only the third time in history that the NYSE experienced prolonged closure, the first time being during the early months of the Great War, and the second in March 1933 during the Great Depression.

 

Trading on the United States bond market also ceased; the leading government bond trader, Cantor Fitzgerald, was based in the World Trade Center. The New York Mercantile Exchange was also closed for a week after the attacks.

 

The Federal Reserve issued a statement, saying:

 

"We are open and operating. The

discount window is available to

meet liquidity needs."

 

The Federal Reserve added $100 billion in liquidity per day during the three days following the attack in order to help avert a financial crisis.

 

Gold prices spiked upwards, from $215.50 to $287 an ounce in London trading. Oil prices also spiked upwards. Gas prices in the United States also briefly shot up, though the spike in prices lasted only about one week.

 

Currency trading continued, with the United States dollar falling sharply against the Euro, British pound, and Japanese yen.

 

The next day, European stock markets fell sharply, including declines of 4.6% in Spain, 8.5% in Germany, and 5.7% on the London Stock Exchange.

 

Stocks in the Latin American markets also plunged, with a 9.2% drop in Brazil, 5.2% drop in Argentina, and 5.6% decline in Mexico, before trading was halted.

 

-- Effect on Economic Sectors

 

In international and domestic markets, stocks of companies in some sectors were hit particularly hard. Travel and entertainment stocks fell, while communications, pharmaceutical and military/defense stocks rose. Online travel agencies particularly suffered, as they cater to leisure travel.

 

-- Insurance Consequences of the Attacks

 

Insurance losses due to 9/11 were more than one and a half times greater than what was previously the largest disaster (Hurricane Andrew) in terms of losses.

 

The losses included business interruption ($11.0 billion), property ($9.6 billion), liability ($7.5 billion), workers compensation ($1.8 billion), and others ($2.5 billion).

 

The firms with the largest losses included Berkshire Hathaway, Lloyd's, Swiss Re, and Munich Re, all of which are reinsurers, with more than $2 billion in losses for each.

 

Shares of major reinsurers, including Swiss Re and Baloise Insurance Group dropped by more than 10%, while shares of Swiss Life dropped 7.8%.

 

Although the insurance industry held reserves that covered the 9/11 attacks, insurance companies were reluctant to continue providing coverage for future terrorist attacks. Only a few insurers continue to offer such coverage.

 

-- Consequences for Airlines and Aviation

 

Flights were grounded in various places across the United States and Canada that did not necessarily have operational support in place, such as dedicated ground crews.

 

A large number of transatlantic flights landed in Gander, Newfoundland and in Halifax, Nova Scotia, with the logistics handled by Transport Canada in Operation Yellow Ribbon.

 

In order to help with the immediate needs of victims' families, United Airlines and American Airlines both provided initial payments of $25,000. The airlines were also required to refund ticket purchases for anyone unable to fly.

 

The 9/11 attacks compounded financial troubles that the airline industry was already experiencing before the attacks. Share prices of airlines and airplane manufacturers plummeted after the attacks.

 

Midway Airlines, already on the brink of bankruptcy, shut down operations almost immediately afterward. Swissair, unable to make payments to creditors on its large debt was grounded on the 2nd. October 2001 and later liquidated.

 

Other airlines were threatened with bankruptcy, and tens of thousands of layoffs were announced in the week following the attacks. To help the industry, the federal government provided an aid package, including $10 billion in loan guarantees, along with $5 billion for short-term assistance.

 

The reduction in air travel demand caused by the attack is also seen as a contributory reason for the retirement of the only supersonic aircraft in service at the time, Concorde.

 

-- Effects of the Attacks on Tourism

 

Tourism in New York City plummeted, causing massive losses in a sector that employed 280,000 people and generated $25 billion per year.

 

In the week following the attack, hotel occupancy fell below 40%, and 3,000 employees were laid off.

 

Tourism, hotel occupancy, and air travel also fell drastically across the nation. The reluctance to fly may have been due to increased fear of a repeat attack. Suzanne Thompson, Professor of Psychology at Pomona College, conducted interviews with 501 people who were not direct victims of 9/11.

 

From this, she concluded that:

 

"Most participants felt more distress

(65%) and a stronger fear of flying

(55%) immediately after the event

than they did before the attacks."

 

-- Effects on Security

 

Since the 9/11 attacks, substantial resources have been put in place in the US towards improving security, in the areas of homeland security, national defense, and in the private sector.

 

-- Effects on New York City

 

In New York City, approximately 430,000 jobs were lost, and there were $2.8 billion in lost wages over the three months following the 9/11 attacks. The economic effects were mainly focused on the city's export economy sectors.

 

The GDP for New York City was estimated to have declined by $30.3 billion over the final three months of 2001 and all of 2002.

 

The Federal government provided $11.2 billion in immediate assistance to the Government of New York City in September 2001, and $10.5 billion in early 2002 for economic development and infrastructure needs.

 

The 9/11 attacks also had great impact on small businesses in Lower Manhattan, located near the World Trade Center. Approximately 18,000 small businesses were destroyed or displaced after the attacks.

 

The Small Business Administration provided loans as assistance, while Community Development Block Grants and Economic Injury Disaster Loans were used by the Federal Government to provide assistance to small business affected by the 9/11 attacks.

 

Other Effects of the Attacks

 

The September 11 attacks also led directly to the U.S. war in Afghanistan, as well as additional homeland security spending.

 

The attacks were also cited as a rationale for the Iraq war.

 

The cost of the two wars so far has surpassed $6 trillion.

 

Brooklyn Bridge

 

The Brooklyn Bridge (shown in the photograph) is a hybrid cable-stayed/suspension bridge. Opened on the 24th. May 1883, the Brooklyn Bridge was the first fixed crossing of the East River.

 

It was also the longest suspension bridge in the world at the time of its opening, with a main span of 1,595.5 feet (486.3 m).

 

The bridge was designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling.

 

Construction started in 1870, with the Tammany Hall-controlled New York Bridge Company overseeing construction, although numerous controversies and the novelty of the design prolonged the project over thirteen years.

 

Since opening, the Brooklyn Bridge has undergone several reconfigurations, having carried horse-drawn vehicles and elevated railway lines until 1950.

 

To alleviate increasing traffic flows, additional bridges and tunnels were built across the East River. Following gradual deterioration, the Brooklyn Bridge has been renovated several times, including in the 1950's, 1980's, and 2010's.

 

The Brooklyn Bridge is the southernmost of the four toll-free vehicular bridges connecting Manhattan Island and Long Island, with the Manhattan Bridge, the Williamsburg Bridge, and the Queensboro Bridge to the north. Only passenger vehicles and pedestrian and bicycle traffic are permitted.

 

A major tourist attraction since its opening, the Brooklyn Bridge has become an icon of New York City. Over the years, the bridge has been used as the location for various stunts and performances, as well as several crimes and attacks.

 

-- Description of Brooklyn Bridge

 

The Brooklyn Bridge, an early example of a steel-wire suspension bridge, uses a hybrid cable-stayed/suspension bridge design, with both vertical and diagonal suspender cables.

 

Its stone towers are neo-Gothic, with characteristic pointed arches. The New York City Department of Transportation (NYCDOT), which maintains the bridge, says that its original paint scheme was "Brooklyn Bridge Tan" and "Silver", although a writer for The New York Post states that it was originally entirely "Rawlins Red".

 

-- The Deck of the Brooklyn Bridge

 

To provide sufficient clearance for shipping in the East River, the Brooklyn Bridge incorporates long approach viaducts on either end to raise it from low ground on both shores.

 

Including approaches, the Brooklyn Bridge is a total of 6,016 feet (1,834 m) long. The main span between the two suspension towers is 1,595.5 feet (486.3 m) long, and 85 feet (26 m) wide.

 

The bridge elongates and contracts between the extremes of temperature from 14 to 16 inches. Navigational clearance is 127 ft (38.7 m) above mean high water. A 1909 Engineering Magazine article said that, at the center of the span, the height could fluctuate by more than 9 feet (2.7 m) due to temperature and traffic loads.

 

At the time of construction, engineers had not yet discovered the aerodynamics of bridge construction, and bridge designs were not tested in wind tunnels.

 

It was coincidental that the open truss structure supporting the deck is, by its nature, subject to fewer aerodynamic problems. This is because John Roebling designed the Brooklyn Bridge's truss system to be six to eight times stronger than he thought it needed to be.

 

However, due to a supplier's fraudulent substitution of inferior-quality cable in the initial construction, the bridge was reappraised at the time as being only four times as strong as necessary.

 

The Brooklyn Bridge can hold a total load of 18,700 short tons, a design consideration from when it originally carried heavier elevated trains.

 

An elevated pedestrian-only promenade runs in between the two roadways and 18 feet (5.5 m) above them. The path is 10 to 17 feet (3.0 to 5.2 m) wide. The iron railings were produced by Janes & Kirtland, a Bronx iron foundry that also made the United States Capitol dome and the Bow Bridge in Central Park.

 

-- The Cables of Brooklyn Bridge

 

The Brooklyn Bridge contains four main cables, which descend from the tops of the suspension towers and support the deck. Each main cable measures 15.75 inches (40.0 cm) in diameter, and contains 5,282 parallel, galvanized steel wires wrapped closely together. These wires are bundled in 19 individual strands, with 278 wires to a strand.

 

This was the first use of bundling in a suspension bridge, and took several months for workers to tie together. Since the 2000's, the main cables have also supported a series of 24-watt LED lighting fixtures, referred to as "necklace lights" due to their shape.

 

1,520 galvanized steel wire suspender cables hang downward from the main cables.

 

-- Brooklyn Bridge Anchorages

 

Each side of the bridge contains an anchorage for the main cables. The anchorages are limestone structures located slightly inland, measuring 129 by 119 feet (39 by 36 m) at the base and 117 by 104 feet (36 by 32 m) at the top.

 

Each anchorage weighs 60,000 short tons. The Manhattan anchorage rests on a foundation of bedrock, while the Brooklyn anchorage rests on clay.

 

The anchorages contain numerous passageways and compartments. Starting in 1876, in order to fund the bridge's maintenance, the New York City government made the large vaults under the bridge's Manhattan anchorage available for rent, and they were in constant use during the early 20th. century.

 

The vaults were used to store wine, as they maintained a consistent 60 °F (16 °C) temperature due to a lack of air circulation. The Manhattan vault was called the "Blue Grotto" because of a shrine to the Virgin Mary next to an opening at the entrance.

 

The vaults were closed for public use in the late 1910's and 1920's during the Great War and Prohibition, but were reopened thereafter.

 

When New York magazine visited one of the cellars in 1978, it discovered a fading inscription on a wall reading:

 

"Who loveth not wine, women and song,

he remaineth a fool his whole life long."

 

Leaks found within the vault's spaces necessitated repairs during the late 1980's and early 1990's. By the late 1990's, the chambers were being used to store maintenance equipment.

 

-- The Towers of the Brooklyn Bridge

 

The bridge's two suspension towers are 278 feet (85 m) tall, with a footprint of 140 by 59 feet (43 by 18 m) at the high water line.

 

They are built of limestone, granite, and Rosendale cement. The limestone was quarried at the Clark Quarry in Essex County, New York. The granite blocks were quarried and shaped on Vinalhaven Island, Maine, under a contract with the Bodwell Granite Company, and delivered from Maine to New York by schooner.

 

The Manhattan tower contains 46,945 cubic yards (35,892 m3) of masonry, while the Brooklyn tower has 38,214 cubic yards (29,217 m3) of masonry.

 

Each tower contains a pair of Gothic Revival pointed arches, through which the roadways run. The arch openings are 117 feet (36 m) tall and 33.75 feet (10.29 m) wide.

 

-- The Brooklyn Bridge Caissons

 

The towers rest on underwater caissons made of southern yellow pine. Both caissons contain interior spaces that were used by construction workers. The Manhattan side's caisson is slightly larger, measuring 172 by 102 feet (52 by 31 m) and located 78.5 feet (23.9 m) below high water, while the Brooklyn side's caisson measures 168 by 102 feet (51 by 31 m) and is located 44.5 feet (13.6 m) below high water.

 

The caissons were designed to hold at least the weight of the towers which would exert a pressure of 5 short tons per square foot when fully built, but the caissons were over-engineered for safety.

 

During an accident on the Brooklyn side, when air pressure was lost and the partially-built towers dropped full-force down, the caisson sustained an estimated pressure of 23 short tons per square foot with only minor damage. Most of the timber used in the bridge's construction, including in the caissons, came from mills at Gascoigne Bluff on St. Simons Island, Georgia.

 

The Brooklyn side's caisson, which was built first, originally had a height of 9.5 feet (2.9 m) and a ceiling composed of five layers of timber, each layer 1 foot (0.30 m) tall. Ten more layers of timber were later added atop the ceiling, and the entire caisson was wrapped in tin and wood for further protection against flooding.

 

The thickness of the caisson's sides was 8 feet (2.4 m) at both the bottom and the top. The caisson had six chambers: two each for dredging, supply shafts, and airlocks.

 

The caisson on the Manhattan side was slightly different because it had to be installed at a greater depth. To protect against the increased air pressure at that depth, the Manhattan caisson had 22 layers of timber on its roof, seven more than its Brooklyn counterpart had. The Manhattan caisson also had fifty 4-inch (10 cm)-diameter pipes for sand removal, a fireproof iron-boilerplate interior, and different airlocks and communication systems.

 

-- History of the Brooklyn Bridge

 

Proposals for a bridge between the then-separate cities of Brooklyn and New York had been suggested as early as 1800. At the time, the only travel between the two cities was by a number of ferry lines.

 

Engineers presented various designs, such as chain or link bridges, though these were never built because of the difficulties of constructing a high enough fixed-span bridge across the extremely busy East River.

 

There were also proposals for tunnels under the East River, but these were considered prohibitively expensive. The current Brooklyn Bridge was conceived by German immigrant John Augustus Roebling in 1852.

 

He had previously designed and constructed shorter suspension bridges, such as Roebling's Delaware Aqueduct in Lackawaxen, Pennsylvania, and the John A. Roebling Suspension Bridge between Cincinnati, Ohio, and Covington, Kentucky.

 

In February 1867, the New York State Senate passed a bill that allowed the construction of a suspension bridge from Brooklyn to Manhattan.

 

Two months later, the New York and Brooklyn Bridge Company was incorporated. There were twenty trustees in total: eight each appointed by the mayors of New York and Brooklyn, as well as the mayors of each city and the auditor and comptroller of Brooklyn.

 

The company was tasked with constructing what was then known as the New York and Brooklyn Bridge. Alternatively, the span was just referred to as the "Brooklyn Bridge", a name originating in a 25th. January 1867 letter to the editor of the Brooklyn Daily Eagle.

 

The act of incorporation, which became law on the 16th. April 1867, authorized the cities of New York (now Manhattan) and Brooklyn to subscribe to $5 million in capital stock, which would fund the bridge's construction.

 

Roebling was subsequently named as the main engineer of the work, and by September 1867, he had presented a master plan of a bridge that would be longer and taller than any suspension bridge previously built.

 

It would incorporate roadways and elevated rail tracks, whose tolls and fares would provide the means to pay for the bridge's construction. It would also include a raised promenade that served as a leisurely pathway.

 

The proposal received much acclaim in both cities, and residents predicted that the New York and Brooklyn Bridge's opening would have as much of an impact as the Suez Canal, the first transatlantic telegraph cable, or the first transcontinental railroad.

 

By early 1869, however, some individuals started to criticize the project, saying either that the bridge was too expensive, or that the construction process was too difficult.

 

To allay concerns about the design of the New York and Brooklyn Bridge, Roebling set up a "Bridge Party" in March 1869, where he invited engineers and members of U.S. Congress to see his other spans. Following the bridge party in April, Roebling and several engineers conducted final surveys.

 

During these surveys, it was determined that the main span would have to be raised from 130 to 135 feet (40 to 41 m), requiring several changes to the overall design.

 

In June 1869, while conducting these surveys, Roebling sustained a crush injury to his foot when a ferry pinned it against a piling. After amputation of his crushed toes, he developed a tetanus infection that left him incapacitated and resulted in his death the following month.

 

Washington Roebling, John Roebling's 32-year-old son, was then hired to fill his father's role. When the younger Roebling was hired, Tammany Hall leader William M. Tweed also became involved in the bridge's construction because, as a major landowner in New York City, he had an interest in the project's completion.

 

The New York and Brooklyn Bridge Company - later known simply as the New York Bridge Company - was actually overseen by Tammany Hall, and it approved Roebling's plans and designated him as chief engineer of the project.

 

-- Construction of the Brooklyn Bridge

 

-- The Caissons

 

Construction of the Brooklyn Bridge began on the 2nd. January 2, 1870. The first work entailed the construction of two caissons, upon which the suspension towers would be built.

 

A caisson is a large watertight chamber, open at the bottom, from which the water is kept out by air pressure and in which construction work may be carried out under water.

 

The Brooklyn side's caisson was built at the Webb & Bell shipyard in Greenpoint, Brooklyn, and was launched into the river on the 19th. March 1870. Compressed air was pumped into the caisson, and workers entered the space to dig the sediment until it sank to the bedrock. As one sixteen-year-old from Ireland, Frank Harris, described the fearful experience:

 

"The six of us were working naked to the waist

in the small iron chamber with the temperature

of about 80 degrees Fahrenheit.

In five minutes the sweat was pouring from us,

and all the while we were standing in icy water

that was only kept from rising by the terrific

pressure. No wonder the headaches were

blinding."

 

Once the caisson had reached the desired depth, it was to be filled in with vertical brick piers and concrete. However, due to the unexpectedly high concentration of large boulders on the riverbed, the Brooklyn caisson took several months to sink to the desired depth.

 

Furthermore, in December 1870, its timber roof caught fire, delaying construction further. The "Great Blowout", as the fire was called, delayed construction for several months, since the holes in the caisson had to be repaired.

 

On the 6th. March 1871, the repairs were finished, and the caisson had reached its final depth of 44.5 feet (13.6 m); it was filled with concrete five days later. Overall, about 264 individuals were estimated to have worked in the caisson every day, but because of high worker turnover, the final total was thought to be about 2,500 men.

 

In spite of this, only a few workers were paralyzed. At its final depth, the caisson's air pressure was 21 pounds per square inch. Normal air pressure is 14.7 psi.

 

The Manhattan side's caisson was the next structure to be built. To ensure that it would not catch fire like its counterpart had, the Manhattan caisson was lined with fireproof plate iron.

 

It was launched from Webb & Bell's shipyard on the 11th. May 1871, and maneuvered into place that September.

 

Due to the extreme underwater air pressure inside the much deeper Manhattan caisson, many workers became sick with "the bends" - decompression sickness - during this work, despite the incorporation of airlocks (which were believed to help with decompression sickness at the time).

 

This condition was unknown at the time, and was first called "caisson disease" by the project physician, Andrew Smith. Between the 25th. January and the 31st. May 1872, Smith treated 110 cases of decompression sickness, while three workers died from the condition.

 

When iron probes underneath the Manhattan caisson found the bedrock to be even deeper than expected, Washington Roebling halted construction due to the increased risk of decompression sickness.

 

After the Manhattan caisson reached a depth of 78.5 feet (23.9 m) with an air pressure of 35 pounds per square inch, Washington deemed the sandy subsoil overlying the bedrock 30 feet (9.1 m) beneath to be sufficiently firm, and subsequently infilled the caisson with concrete in July 1872.

 

Washington Roebling himself suffered a paralyzing injury as a result of caisson disease shortly after ground was broken for the Brooklyn tower foundation.

 

His debilitating condition left him unable to supervise the construction in person, so he designed the caissons and other equipment from his apartment, directing the completion of the bridge through a telescope in his bedroom.

 

His wife, Emily Warren Roebling, not only provided written communications between her husband and the engineers on site, but also understood mathematics, calculations of catenary curves, strengths of materials, bridge specifications, and the intricacies of cable construction.

 

She spent the next 11 years helping supervise the bridge's construction, taking over much of the chief engineer's duties, including day-to-day supervision and project management.

 

-- The Towers of the Brooklyn Bridge

 

After the caissons were completed, piers were constructed on top of each of them upon which masonry towers would be built. The towers' construction was a complex process that took four years.

 

Since the masonry blocks were heavy, the builders transported them to the base of the towers using a pulley system with a continuous 1.5-inch (3.8 cm)-diameter steel wire rope, operated by steam engines at ground level.

 

The blocks were then carried up on a timber track alongside each tower and maneuvered into the proper position using a derrick atop the towers. The blocks sometimes vibrated the ropes because of their weight, but only once did a block fall.

 

Construction of the suspension towers started in mid-1872, and by the time work was halted for the winter in late 1872, parts of each tower had already been built. By mid-1873, there was substantial progress on the towers' construction.

 

The arches of the Brooklyn tower were completed by August 1874. The tower was substantially finished by December 1874, with the erection of saddle plates for the main cables at the top of the tower.

 

The last stone on the Brooklyn tower was raised in June 1875, and the Manhattan tower was completed in July 1876.

 

The work was dangerous: by 1876, three workers had died having fallen from the towers, while nine other workers were killed in other accidents.

 

By 1875, while the towers were being constructed, the project had depleted its original $5 million budget. Two bridge commissioners, one each from Brooklyn and Manhattan, petitioned New York state lawmakers to allot another $8 million for construction. Legislators authorized the money on condition that the cities would buy the stock of Brooklyn Bridge's private stockholders.

 

Work proceeded concurrently on the anchorages on each side. The Brooklyn anchorage broke ground in January 1873 and was substantially completed by August 1875.

 

The Manhattan anchorage was built in less time. Having started in May 1875, it was mostly completed by July 1876. The anchorages could not be fully completed until the main cables were spun, at which point another 6 feet (1.8 m) would be added to the height of each 80-foot (24 m) anchorage.

 

-- The Brooklyn Bridge Cables

 

The first temporary wire was stretched between the towers on the 15th. August 1876, using chrome steel provided by the Chrome Steel Company of Brooklyn. The wire was then stretched back across the river, and the two ends were spliced to form a traveler, a lengthy loop of wire connecting the towers, which was driven by a 30 horsepower (22 kW) steam hoisting engine at ground level.

 

The wire was one of two that were used to create a temporary footbridge for workers while cable spinning was ongoing. The next step was to send an engineer across the completed traveler wire in a boatswain's chair slung from the wire, to ensure it was safe enough.

 

The bridge's master mechanic, E. F. Farrington, was volunteered for this task, and an estimated crowd of 10,000 people on both shores watched him cross.

 

A second traveler wire was then stretched across the span. The temporary footbridge, located some 60 feet (18 m) above the elevation of the future deck, was completed in February 1877.

 

By December 1876, a steel contract for the permanent cables still had not been awarded. There was disagreement over whether the bridge's cables should use the as-yet-untested Bessemer steel, or the well-proven crucible steel.

 

Until a permanent contract was awarded, the builders ordered 30 short tons of wire in the interim, 10 tons each from three companies, including Washington Roebling's own steel mill in Brooklyn.

 

In the end, it was decided to use number 8 Birmingham gauge (approximately 4 mm or 0.165 inches in diameter) crucible steel, and a request for bids was distributed, to which eight companies responded.

 

In January 1877, a contract for crucible steel was awarded to J. Lloyd Haigh, who was associated with bridge trustee Abram Hewitt, whom Roebling distrusted.

 

The spinning of the wires required the manufacture of large coils of it which were galvanized but not oiled when they left the factory. The coils were delivered to a yard near the Brooklyn anchorage. There they were dipped in linseed oil, hoisted to the top of the anchorage, dried out and spliced into a single wire, and finally coated with red zinc for further galvanizing.

 

There were thirty-two drums at the anchorage yard, eight for each of the four main cables. Each drum had a capacity of 60,000 feet (18,000 m) of wire. The first experimental wire for the main cables was stretched between the towers on the 29th. May 29 1877, and spinning began two weeks later.

 

All four main cables had been strung by that July. During that time, the temporary footbridge was unofficially opened to members of the public, who could receive a visitor's pass; by August 1877 several thousand visitors from around the world had used the footbridge. The visitor passes ceased that September after a visitor had an epileptic seizure and nearly fell off.

 

As the wires were being spun, work also commenced on the demolition of buildings on either side of the river for the Brooklyn Bridge's approaches; this work was mostly complete by September 1877. The following month, initial contracts were awarded for the suspender wires, which would hang down from the main cables and support the deck. By May 1878, the main cables were more than two-thirds complete.

 

However, the following month, one of the wires slipped, killing two people and injuring three others. In 1877, Hewitt wrote a letter urging against the use of Bessemer steel in the bridge's construction. Bids had been submitted for both crucible steel and Bessemer steel; John A. Roebling's Sons submitted the lowest bid for Bessemer steel, but at Hewitt's direction, the contract was awarded to Haigh.

 

A subsequent investigation discovered that Haigh had substituted inferior quality wire in the cables. Of eighty rings of wire that were tested, only five met standards, and it was estimated that Haigh had earned $300,000 from the deception.

 

At this point, it was too late to replace the cables that had already been constructed. Roebling determined that the poorer wire would leave the bridge only four times as strong as necessary, rather than six to eight times as strong. The inferior-quality wire was allowed to remain, and 150 extra wires were added to each cable.

 

To avoid public controversy, Haigh was not fired, but instead was required to personally pay for higher-quality wire. The contract for the remaining wire was awarded to the John A. Roebling's Sons, and by the 5th. October 1878, the last of the main cables' wires went over the river.

 

After the suspender wires had been placed, workers began erecting steel crossbeams to support the roadway as part of the bridge's overall superstructure. Construction on the bridge's superstructure started in March 1879, but, as with the cables, the trustees initially disagreed on whether the steel superstructure should be made of Bessemer or crucible steel.

 

That July, the trustees decided to award a contract for 500 short tons of Bessemer steel to the Edgemoor Iron Works, based in Philadelphia. The trustees later ordered another 500 short tons of Bessemer steel. However, by February 1880 the steel deliveries had not started.

 

That October, the bridge trustees questioned Edgemoor's president about the delay in steel deliveries. Despite Edgemoor's assurances that the contract would be fulfilled, the deliveries still had not been completed by November 1881.

 

Brooklyn mayor Seth Low, who became part of the board of trustees in 1882, became the chairman of a committee tasked to investigate Edgemoor's failure to fulfill the contract. When questioned, Edgemoor's president stated that the delays were the fault of another contractor, the Cambria Iron Company, who were manufacturing the eyebars for the bridge trusses.

 

Further complicating the situation, Washington Roebling had failed to appear at the trustees' meeting in June 1882, since he had gone to Newport, Rhode Island. After the news media discovered this, most of the newspapers called for Roebling to be fired as chief engineer, except for the Daily State Gazette of Trenton, New Jersey, and the Brooklyn Daily Eagle.

 

Some of the longstanding trustees were willing to vouch for Roebling, since construction progress on the Brooklyn Bridge was still ongoing. However, Roebling's behavior was considered suspect among the younger trustees who had joined the board more recently.

 

Construction progress on the bridge itself was submitted in formal monthly reports to the mayors of New York and Brooklyn. For example, the August 1882 report noted that the month's progress included 114 intermediate cords erected within a week, as well as 72 diagonal stays, 60 posts, and numerous floor beams, bridging trusses, and stay bars.

 

By early 1883, the Brooklyn Bridge was considered mostly completed and was projected to open that June. Contracts for bridge lighting were awarded by February 1883, and a toll scheme was approved that March.

 

-- Opposition to the Bridge

 

There was substantial opposition to the bridge's construction from shipbuilders and merchants located to the north, who argued that the bridge would not provide sufficient clearance underneath for ships.

 

In May 1876, these groups, led by Abraham Miller, filed a lawsuit in the United States District Court against the cities of New York and Brooklyn.

 

In 1879, an Assembly Sub-Committee on Commerce and Navigation began an investigation into the Brooklyn Bridge. A seaman who had been hired to determine the height of the span, testified to the committee about the difficulties that ship masters would experience in bringing their ships under the bridge when it was completed.

 

Another witness, Edward Wellman Serrell, a civil engineer, said that the calculations of the bridge's assumed strength were incorrect.

 

However the Supreme Court decided in 1883 that the Brooklyn Bridge was a lawful structure.

 

The Opening of the Brooklyn Bridge

 

The Brooklyn Bridge was opened for use on the 24th. May 1883. Thousands of people attended the opening ceremony, and many ships were present in the East River for the occasion. Officially, Emily Warren Roebling was the first to cross the bridge.

 

The bridge opening was also attended by U.S. president Chester A. Arthur and New York mayor Franklin Edson, who crossed the bridge and shook hands with Brooklyn mayor Seth Low at the Brooklyn end. Abram Hewitt gave the principal address:

 

"It is not the work of any one man or of any one

age. It is the result of the study, of the experience,

and of the knowledge of many men in many ages.

It is not merely a creation; it is a growth. It stands

before us today as the sum and epitome of human

knowledge; as the very heir of the ages; as the

latest glory of centuries of patient observation,

profound study and accumulated skill, gained,

step by step, in the never-ending struggle of man

to subdue the forces of nature to his control and use."

 

Although Washington Roebling was unable to attend the ceremony (and rarely visited the site again), he held a celebratory banquet at his house on the day of the bridge opening.

 

Further festivity included a performance by a band, gunfire from ships, and a fireworks display. On that first day, a total of 1,800 vehicles and 150,300 people crossed the span.

 

Less than a week after the Brooklyn Bridge opened, ferry crews reported a sharp drop in patronage, while the bridge's toll operators were processing over a hundred people a minute. However, cross-river ferries continued to operate until 1942.

 

The bridge had cost US$15.5 million in 1883 dollars (about US$436,232,000 in 2021) to build, of which Brooklyn paid two-thirds. The bonds to fund the construction were not paid off until 1956.

 

An estimated 27 men died during the bridge's construction. Until the construction of the nearby Williamsburg Bridge in 1903, the Brooklyn Bridge was the longest suspension bridge in the world, 20% longer than any built previously.

 

At the time of opening, the Brooklyn Bridge was not complete; the proposed public transit across the bridge was still being tested, while the Brooklyn approach was being completed.

 

On the 30th. May 1883, six days after the opening, a woman falling down a stairway at the Brooklyn approach caused a stampede which resulted in at least twelve people being crushed and killed.

 

In subsequent lawsuits, the Brooklyn Bridge Company was acquitted of negligence. However, the company did install emergency phone boxes and additional railings, and the trustees approved a fireproofing plan for the bridge.

 

Public transit service began with the opening of the New York and Brooklyn Bridge Railway, a cable car service, on the 25th. September 1883.

 

On the 17th. May 1884, one of P. T. Barnum's most famous attractions, Jumbo the elephant, led a parade of 21 elephants over the Brooklyn Bridge. This helped to lessen doubts about the bridge's stability while also promoting Barnum's circus.

 

-- Brooklyn Bridge in the Late 19th. & Early 20th. Centuries

 

Movement across the Brooklyn Bridge increased in the years after it opened; a million people paid to cross in the first six months. The bridge carried 8.5 million people in 1884, its first full year of operation; this number doubled to 17 million in 1885, and again to 34 million in 1889.

 

Many of these people were cable car passengers. Additionally, about 4.5 million pedestrians a year were crossing the bridge for free by 1892.

 

The first proposal to make changes to the bridge was sent in only two and a half years after it opened; Linda Gilbert suggested glass steam-powered elevators and an observatory be added to the bridge and a fee charged for use, which would in part fund the bridge's upkeep and in part fund her prison reform charity.

 

This proposal was considered, but not acted upon. Numerous other proposals were made during the first fifty years of the bridge's life.

 

Trolley tracks were added in the center lanes of both roadways in 1898, allowing trolleys to use the bridge as well.

 

Concerns about the Brooklyn Bridge's safety were raised during the turn of the century. In 1898, traffic backups due to a dead horse caused one of the truss cords to buckle.

 

There were more significant worries after twelve suspender cables snapped in 1901, although a thorough investigation found no other defects.

 

After the 1901 incident, five inspectors were hired to examine the bridge each day, a service that cost $250,000 a year.

 

The Brooklyn Rapid Transit Company, which operated routes across the Brooklyn Bridge, issued a notice in 1905 saying that the bridge had reached its transit capacity.

 

Although a second deck for the Brooklyn Bridge was proposed, it was thought to be infeasible because doing so would overload the bridge's structural capacity.

 

Though tolls had been instituted for carriages and cable-car customers since the bridge's opening, pedestrians were spared from the tolls originally. However, by the first decade of the 20th. century, pedestrians were also paying tolls.

 

However tolls on all four bridges across the East River - the Brooklyn Bridge, as well as the Manhattan, Williamsburg, and Queensboro bridges to the north - were abolished in July 1911 as part of a populist policy initiative headed by New York City mayor William Jay Gaynor.

 

Ostensibly in an attempt to reduce traffic on nearby city streets, Grover Whalen, the commissioner of Plant and Structures, banned motor vehicles from the Brooklyn Bridge in 1922. The real reason for the ban was an incident the same year where two cables slipped due to high traffic loads.

 

Both Whalen and Roebling called for the renovation of the Brooklyn Bridge and the construction of a parallel bridge, although the parallel bridge was never built.

 

-- Brooklyn Bridge in Mid- to late 20th. Century

 

-- Upgrades to the Bridge

 

The first major upgrade to the Brooklyn Bridge commenced in 1948, when a contract for redesigning the roadways was awarded to David B. Steinman. The renovation was expected to double the capacity of the bridge's roadways to nearly 6,000 cars per hour, at a projected cost of $7 million.

 

The renovation included the demolition of both the elevated and the trolley tracks on the roadways and the widening of each roadway from two to three lanes, as well as the construction of a new steel-and-concrete floor.

 

In addition, new ramps were added to Adams Street, Cadman Plaza, and the Brooklyn Queens Expressway (BQE) on the Brooklyn side, and to Park Row on the Manhattan side. The trolley tracks closed in March 1950 to allow for the widening work to occur.

 

During the construction project, one roadway at a time was closed, allowing reduced traffic flows to cross the bridge in one direction only. The widened south roadway was completed in May 1951, followed by the north roadway in October 1953. In addition, defensive barriers were added to the bridge as a safeguard against sabotage.

 

The restoration was finished in May 1954 with the completion of the reconstructed elevated promenade.

 

While the rebuilding of the span was ongoing, a fallout shelter was constructed beneath the Manhattan approach in anticipation of the Cold War. The abandoned space in one of the masonry arches was stocked with emergency survival supplies for a potential nuclear attack by the Soviet Union; these supplies were still in place half a century later.

 

A repainting of the bridge was announced in advance of its 90th. anniversary.

 

-- Deterioration and Late-20th. Century Repair

 

The Brooklyn Bridge gradually deteriorated due to age and neglect. While it had 200 full-time dedicated maintenance workers before World War II, that number had dropped to five by the late 20th. century, and the city as a whole only had 160 bridge maintenance workers.

 

In 1974, heavy vehicles such as vans and buses were banned from the bridge to prevent further erosion of the concrete roadway. A report in The New York Times four years later noted that the cables were visibly fraying, and that the pedestrian promenade had holes in it.

 

The city began planning to replace all the Brooklyn Bridge's cables at a cost of $115 million, as part of a larger project to renovate all four toll-free East River spans.

 

By 1980, the Brooklyn Bridge was in such dire condition that it faced imminent closure. In some places, half of the strands in the cables were broken.

 

In June 1981, two of the diagonal stay cables snapped, seriously injuring a pedestrian who later died. Subsequently, the anchorages were found to have developed rust, and an emergency cable repair was necessitated less than a month later after another cable developed slack.

 

Following the incident, the city accelerated the timetable of its proposed cable replacement, and it commenced a $153 million rehabilitation of the Brooklyn Bridge in advance of the 100th anniversary.

 

As part of the project, the bridge's original suspender cables installed by J. Lloyd Haigh were replaced by Bethlehem Steel in 1986, marking the cables' first replacement since construction. In a smaller project, the bridge was floodlit at night, starting in 1982 to highlight its architectural features.

 

Additional problems persisted, and in 1993, high levels of lead were discovered near the bridge's towers. Further emergency repairs were undertaken in mid-1999 after small concrete shards began falling from the bridge into the East River. The concrete deck had been installed during the 1950's renovations, and had a lifespan of about 60 years.

 

-- Brooklyn Bridge in the 21st. Century

 

The Park Row exit from the bridge's westbound lanes was closed as a safety measure after the September 11, 2001, attacks on the nearby World Trade Center. That section of Park Row was closed since it ran right underneath 1 Police Plaza, the headquarters of the New York City Police Department.

 

In early 2003, to save money on electricity, the bridge's "necklace lights" were turned off at night. They were turned back on later that year after several private entities made donations to fund the lights.

 

After the 2007 collapse of the I-35W bridge in Minneapolis, public attention focused on the condition of bridges across the U.S. The New York Times reported that the Brooklyn Bridge approach ramps had received a "poor" rating during an inspection in 2007.

 

However, a NYCDOT spokesman said that the poor rating did not indicate a dangerous state but rather implied it required renovation. In 2010, the NYCDOT began renovating the approaches and deck, as well as repainting the suspension span.

 

Work included widening two approach ramps from one to two lanes by re-striping a new prefabricated ramp; seismic retrofitting; replacement of rusted railings and safety barriers; and road deck resurfacing. The work necessitated detours for four years.

 

At the time, the project was scheduled to be completed in 2014, but completion was later delayed to 2015, then again to 2017. The project's cost also increased from $508 million in 2010 to $811 million in 2016.

 

In August 2016, after the renovation had been completed, the NYCDOT announced that it would conduct a seven-month, $370,000 study to verify if the bridge could support a heavier upper deck that consisted of an expanded bicycle and pedestrian path.

 

As of 2016, about 10,000 pedestrians and 3,500 cyclists used the pathway on an average weekday. Work on the pedestrian entrance on the Brooklyn side was underway by 2017.

 

The NYCDOT also indicated in 2016 that it planned to reinforce the Brooklyn Bridge's foundations to prevent it from sinking, as well as repair the masonry arches on the approach ramps, which had been damaged by Hurricane Sandy in 2012.

 

In July 2018, the New York City Landmarks Preservation Commission approved a further renovation of the Brooklyn Bridge's suspension towers and approach ramps. That December, the federal government gave the city $25 million in funding, which would contribute to a $337 million rehabilitation of the bridge approaches and the suspension towers. Work started in late 2019 and was scheduled to be completed in 2023.

 

-- Usage of the Brooklyn Bridge

 

Horse-drawn carriages have been allowed to use the Brooklyn Bridge's roadways since its opening. Originally, each of the two roadways carried two lanes of a different direction of traffic. The lanes were relatively narrow at only 8 feet (2.4 m) wide. In 1922, motor vehicles were banned from the bridge, while horse-drawn carriages were restricted from the Manhattan Bridge. Thereafter, the only vehicles allowed on the Brooklyn Bridge were horse-drawn.

 

By 1950, the main roadway carried six lanes of automobile traffic, three in each direction. It was then reduced to five lanes with the addition of a two-way bike lane on the Manhattan-bound side in 2021.

 

Because of the roadway's height (11 ft (3.4 m)) and weight (6,000 lb (2,700 kg)) restrictions, commercial vehicles and buses are prohibited from using the Brooklyn Bridge.

 

The weight restrictions prohibit heavy passenger vehicles such as pickup trucks and SUVs from using the bridge, though this is not often enforced in practice.

 

Formerly, rail traffic operated on the Brooklyn Bridge as well. Cable cars and elevated railroads used the bridge until 1944, while trolleys ran until 1950.

 

A cable car service began operating on the 25th. September 1883; it ran on the inner lanes of the bridge, between terminals at the Manhattan and Brooklyn ends.

 

Since Washington Roebling believed that steam locomotives would put excessive loads upon the structure of the Brooklyn Bridge, the cable car line was designed as a steam/cable-hauled hybrid.

 

They were powered from a generating station under the Brooklyn approach. The cable cars could not only regulate their speed on the 3.75% upward and downward approaches, but also maintain a constant interval between each other. There were 24 cable cars in total.

 

Initially, the service ran with single-car trains, but patronage soon grew so much that by October 1883, two-car trains were in use. The line carried three million people in the first six months, nine million in 1884, and nearly 20 million in 1885.

 

Patronage continued to increase, and in 1888, the tracks were lengthened and even more cars were constructed to allow for four-car cable car trains. Electric wires for the trolleys were added by 1895, allowing for the potential future decommissioning of the steam/cable system.

 

The terminals were rebuilt once more in July 1895, and, following the implementation of new electric cars in late 1896, the steam engines were dismantled and sold.

 

-- The Brooklyn Bridge Walkway

 

The Brooklyn Bridge has an elevated promenade open to pedestrians in the center of the bridge, located 18 feet (5.5 m) above the automobile lanes.

 

The path is generally 10 to 17 feet (3.0 to 5.2 m) wide, though this is constrained by obstacles such as protruding cables, benches, and stairways, which create "pinch points" at certain locations. The path narrows to 10 feet (3.0 m) at the locations where the main cables descend to the level of the promenade.

 

Further exacerbating the situation, these "pinch points" are some of the most popular places to take pictures. As a result, in 2016, the NYCDOT announced that it planned to double the promenade's width.

 

On the 14th. September 2021, the DOT closed off the inner-most car lane on the Manhattan-bound side with protective barriers and fencing to create a new bike path. Cyclists are now prohibited from the upper pedestrian lane.

 

-- Emergency Use of Brooklyn Bridge

 

While the bridge has always permitted the passage of pedestrians, the promenade facilitates movement when other means of crossing the East River have become unavailable.

 

During transit strikes by the Transport Workers Union in 1980 and 2005, people commuting to work used the bridge; they were joined by Mayors Ed Koch and Michael Bloomberg, who crossed as a gesture to the affected public.

 

Pedestrians also walked across the bridge as an alternative to suspended subway services following the 1965, 1977, and 2003 blackouts, and after the September 11 attacks on the World Trade Center.

 

During the 2003 blackouts, many crossing the bridge reported a swaying motion. The higher-than-usual pedestrian load caused this swaying, which was amplified by the tendency of pedestrians to synchronize their footfalls with a sway.

 

Several engineers expressed concern about how this would affect the bridge, although others noted that the bridge did withstand the event and that the redundancies in its design - the inclusion of the three support systems (suspension system, diagonal stay system, and stiffening truss) - make it probably the best secured bridge against such movements going out of control.

 

In designing the bridge, John Roebling had stated that the bridge would sag but not fall, even if one of these structural systems were to fail altogether.

 

-- Stunts Associated With Brooklyn Bridge

 

There have been several notable jumpers from the Brooklyn Bridge:

 

-- The first person was Robert Emmet Odlum, brother of women's rights activist Charlotte Odlum Smith, on the 19th. May 1885. He struck the water at an angle, and died shortly afterwards from internal injuries.

 

-- Steve Brodie supposedly dropped from underneath the bridge in July 1886 and was briefly arrested for it, although there is some doubt about whether he actually jumped.

 

-- Larry Donovan made a slightly higher jump from the railing a month afterward.

 

Other notable events have taken place on or near the bridge:

 

-- In 1919, Giorgio Pessi piloted what was then one of the world's largest airplanes, the Caproni Ca.5, under the bridge.

 

-- At 9:00 a.m. on the 19th. May 1977, artist Jack Bashkow climbed one of the towers for 'Bridging', which was termed a "media sculpture" by the performance group Art Corporation of America Inc.

 

Seven artists climbed the largest bridges connected to Manhattan in order to:

 

"Replace violence and fear

in mass media for one day".

 

When each of the artists had reached the tops of the bridges, they ignited bright-yellow flares at the same moment, resulting in rush hour traffic disruption, media attention, and the arrest of the climbers, though the charges were later dropped.

 

Called "The first social-sculpture to use mass-media as art” by conceptual artist Joseph Beuys, the event was on the cover of the New York Post, it received international attention, and received ABC Eyewitness News' 1977 Best News of the Year award.

 

John Halpern documented the incident in the film 'Bridging' (1977)

 

-- Halpern attempted another "Bridging" "social sculpture" in 1979, when he planted a radio receiver, gunpowder and fireworks in a bucket atop one of the Brooklyn Bridge towers.

 

The piece was later discovered by police, leading to his arrest for possessing a bomb.

 

-- In 1993, bridge jumper Thierry Devaux illegally performed eight acrobatic bungee jumps above the East River close to the Brooklyn tower.

 

-- On the 1st. October 2011, more than 700 protesters with the Occupy Wall Street movement were arrested while attempting to march across the bridge on the roadway.

 

Protesters disputed the police account of the event, and claimed that the arrests were the result of being trapped on the bridge by the NYPD. The majority of the arrests were subsequently dismissed.

 

-- On the 22nd. July 2014, the two American flags on the flagpoles atop each tower were found to have been replaced by bleached-white American flags.

 

Initially, cannabis activism was suspected as a motive, but on the 12th. August 2014, two Berlin artists claimed responsibility for hoisting the two white flags, having switched the original flags with their replicas.

 

The artists said that the flags were meant to celebrate the beauty of public space and the anniversary of the death of German-born John Roebling, and they denied that it was an anti-American statement.

 

-- Brooklyn Bridge as a Suicide Spot

 

The first person to jump from the bridge with the intention of suicide was Francis McCarey in 1892.

 

A lesser-known early jumper was James Duffy of County Cavan, Ireland, who on the 15th. April 1895 asked several men to watch him jump from the bridge. Duffy jumped and was not seen again.

 

Additionally, the cartoonist Otto Eppers jumped and survived in 1910, and was then tried and acquitted for attempted suicide.

 

The Brooklyn Bridge has since developed a reputation as a suicide bridge due to the number of jumpers who do so intending to kill themselves, though exact statistics are difficult to find.

 

-- Crimes and Terrorism Associated With Brooklyn Bridge

 

-- In 1979, police disarmed a stick of dynamite placed under the Brooklyn approach, and an artist in Manhattan was later arrested for the act.

 

-- On the 1st. March 1994, Lebanese-born Rashid Baz opened fire on a van carrying members of the Chabad-Lubavitch Orthodox Jewish Movement, striking 16-year-old student Ari Halberstam and three others traveling on the bridge.

 

Halberstam died five days later from his wounds, and Baz was later convicted of murder. He was apparently acting out of revenge for the Hebron massacre of Palestinian Muslims a few days prior to the incident.

 

After initially classifying the killing as one committed out of road rage, the Justice Department reclassified the case in 2000 as a terrorist attack.

 

The entrance ramp to the bridge on the Manhattan side was subsequently dedicated as the Ari Halberstam Memorial Ramp.

 

-- In 2003, truck driver Lyman Faris was sentenced to 20 years in prison for providing material support to Al-Qaeda, after an earlier plot to destroy the bridge by cutting through its support wires with blowtorches was thwarted.

 

-- Brooklyn Bridge Anniversary Celebrations

 

-- The 50th.-anniversary celebrations on the 24th. May 1933 included a ceremony featuring an airplane show, ships, and fireworks, as well as a banquet.

 

-- During the centennial celebrations on the 24th. May 1983, President Ronald Reagan led a cavalcade of cars across the bridge.

 

A flotilla of ships visited the harbor, officials held parades, and Grucci Fireworks held a fireworks display that evening.

 

For the centennial, the Brooklyn Museum exhibited a selection of the original drawings made for the bridge.

 

-- Culture

 

The Brooklyn Bridge has had an impact on idiomatic American English. For example, references to "Selling the Brooklyn Bridge" abound in American culture, sometimes as examples of rural gullibility, but more often in connection with an idea that strains credulity.

 

George C. Parker and William McCloundy were two early 20th.-century con men who may have perpetrated this scam successfully on unwitting tourists, although the author of 'The Brooklyn Bridge: A Cultural History' wrote:

 

"No evidence exists that the bridge

has ever been sold to a 'gullible

outlander'".

 

However, anyone taken in by fraudsters is hardly likely to publicize the fact.

 

A popular tradition on Brooklyn Bridge is for couples to inscribe a date and their initials onto a padlock, attach it to the bridge, and throw the key into the water as a sign of their love.

 

The practice of attaching 'love locks' to the bridge is officially illegal in New York City, and in theory the NYPD can give violators a $100 fine.

 

NYCDOT workers periodically remove the love locks from the bridge at a cost of $100,000 per year.

 

-- Brooklyn Bridge in the Media

 

The bridge is often featured in wide shots of the New York City skyline in television and film, and has been depicted in numerous works of art.

 

Fictional works have used the Brooklyn Bridge as a setting; for instance, the dedication of a portion of the bridge, and the bridge itself, were key components in the 2001 film Kate & Leopold.

 

Furthermore, the Brooklyn Bridge has also served as an icon of America, with mentions in numerous songs, books, and poems.

 

Among the most notable of these works is that of American Modernist poet Hart Crane, who used the Brooklyn Bridge as a central metaphor and organizing structure for his second book of poetry, 'The Bridge' (1930).

 

The Brooklyn Bridge has also been lauded for its architecture. One of the first positive reviews was "The Bridge as a Monument", a Harper's Weekly piece written by architecture critic Montgomery Schuyler and published a week after the bridge's opening.

 

In the piece, Schuyler wrote:

 

"It so happens that the work which is likely to be

our most durable monument, and to convey some

knowledge of us to the most remote posterity, is a

work of bare utility; not a shrine, not a fortress, not

a palace, but a bridge."

 

Architecture critic Lewis Mumford cited the piece as the impetus for serious architectural criticism in the U.S. He wrote that in the 1920's the bridge was a source of joy and inspiration in his childhood, and that it was a profound influence in his adolescence.

 

Later critics regarded the Brooklyn Bridge as a work of art, as opposed to an engineering feat or a means of transport.

 

Not all critics appreciated the bridge, however. Henry James, writing in the early 20th. century, cited the bridge as an ominous symbol of the city's transformation into a "steel-souled machine room".

 

The construction of the Brooklyn Bridge is detailed in numerous media sources, including David McCullough's 1972 book 'The Great Bridge', and Ken Burns's 1981 documentary 'Brooklyn Bridge'.

 

It is also described in 'Seven Wonders of the Industrial World', a BBC docudrama series with an accompanying book, as well as in 'Chief Engineer: Washington Roebling, The Man Who Built the Brooklyn Bridge', a biography published in 2017.

The Brooklyn Bridge

 

The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge. Opened on the 24th. May 1883, the Brooklyn Bridge was the first fixed crossing of the East River.

 

It was also the longest suspension bridge in the world at the time of its opening, with a main span of 1,595.5 feet (486.3 m).

 

Note the slight upward curve of the main span. The decks of all suspension bridges are designed in this way, because the curve helps to dissipate the force of the weight of the people and vehicles on the bridge lengthways instead of downwards like on a linear bridge.

 

The curve produces a horizontal thrust restrained by the abutments at either end. This means that the bridge can handle more weight without breaking.

 

The bridge was designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling.

 

Construction started in 1870, with the Tammany Hall-controlled New York Bridge Company overseeing construction, although numerous controversies and the novelty of the design prolonged the project over thirteen years.

 

Since opening, the Brooklyn Bridge has undergone several reconfigurations, having carried horse-drawn vehicles and elevated railway lines until 1950.

 

To alleviate increasing traffic flows, additional bridges and tunnels were built across the East River. Following gradual deterioration, the Brooklyn Bridge has been renovated several times, including in the 1950's, 1980's, and 2010's.

 

The Brooklyn Bridge is the southernmost of the four toll-free vehicular bridges connecting Manhattan Island and Long Island, with the Manhattan Bridge, the Williamsburg Bridge, and the Queensboro Bridge to the north. Only passenger vehicles and pedestrian and bicycle traffic are permitted.

 

A major tourist attraction since its opening, the Brooklyn Bridge has become an icon of New York City. Over the years, the bridge has been used as the location for various stunts and performances, as well as several crimes and attacks.

 

Description of Brooklyn Bridge

 

The Brooklyn Bridge, an early example of a steel-wire suspension bridge, uses a hybrid cable-stayed/suspension bridge design, with both vertical and diagonal suspender cables.

 

Its stone towers are neo-Gothic, with characteristic pointed arches. The New York City Department of Transportation (NYCDOT), which maintains the bridge, says that its original paint scheme was "Brooklyn Bridge Tan" and "Silver", although a writer for The New York Post states that it was originally entirely "Rawlins Red".

 

The Deck of the Brooklyn Bridge

 

To provide sufficient clearance for shipping in the East River, the Brooklyn Bridge incorporates long approach viaducts on either end to raise it from low ground on both shores.

 

Including approaches, the Brooklyn Bridge is a total of 6,016 feet (1,834 m) long. The main span between the two suspension towers is 1,595.5 feet (486.3 m) long, and 85 feet (26 m) wide.

 

The bridge elongates and contracts between the extremes of temperature from 14 to 16 inches. Navigational clearance is 127 ft (38.7 m) above mean high water. A 1909 Engineering Magazine article said that, at the center of the span, the height could fluctuate by more than 9 feet (2.7 m) due to temperature and traffic loads.

 

At the time of construction, engineers had not yet discovered the aerodynamics of bridge construction, and bridge designs were not tested in wind tunnels.

 

It was coincidental that the open truss structure supporting the deck is, by its nature, subject to fewer aerodynamic problems. This is because John Roebling designed the Brooklyn Bridge's truss system to be six to eight times stronger than he thought it needed to be.

 

However, due to a supplier's fraudulent substitution of inferior-quality cable in the initial construction, the bridge was reappraised at the time as being only four times as strong as necessary.

 

The Brooklyn Bridge can hold a total load of 18,700 short tons, a design consideration from when it originally carried heavier elevated trains.

 

An elevated pedestrian-only promenade runs in between the two roadways and 18 feet (5.5 m) above them. The path is 10 to 17 feet (3.0 to 5.2 m) wide. The iron railings were produced by Janes & Kirtland, a Bronx iron foundry that also made the United States Capitol dome and the Bow Bridge in Central Park.

 

The Cables of Brooklyn Bridge

 

The Brooklyn Bridge contains four main cables, which descend from the tops of the suspension towers and support the deck. Each main cable measures 15.75 inches (40.0 cm) in diameter, and contains 5,282 parallel, galvanized steel wires wrapped closely together. These wires are bundled in 19 individual strands, with 278 wires to a strand.

 

This was the first use of bundling in a suspension bridge, and took several months for workers to tie together. Since the 2000's, the main cables have also supported a series of 24-watt LED lighting fixtures, referred to as "necklace lights" due to their shape.

 

1,520 galvanized steel wire suspender cables hang downward from the main cables.

 

Brooklyn Bridge Anchorages

 

Each side of the bridge contains an anchorage for the main cables. The anchorages are limestone structures located slightly inland, measuring 129 by 119 feet (39 by 36 m) at the base and 117 by 104 feet (36 by 32 m) at the top.

 

Each anchorage weighs 60,000 short tons. The Manhattan anchorage rests on a foundation of bedrock, while the Brooklyn anchorage rests on clay.

 

The anchorages contain numerous passageways and compartments. Starting in 1876, in order to fund the bridge's maintenance, the New York City government made the large vaults under the bridge's Manhattan anchorage available for rent, and they were in constant use during the early 20th. century.

 

The vaults were used to store wine, as they maintained a consistent 60 °F (16 °C) temperature due to a lack of air circulation. The Manhattan vault was called the "Blue Grotto" because of a shrine to the Virgin Mary next to an opening at the entrance.

 

The vaults were closed for public use in the late 1910's and 1920's during the Great War and Prohibition, but were reopened thereafter.

 

When New York magazine visited one of the cellars in 1978, it discovered a fading inscription on a wall reading:

 

"Who loveth not wine, women and song,

he remaineth a fool his whole life long."

 

Leaks found within the vault's spaces necessitated repairs during the late 1980's and early 1990's. By the late 1990's, the chambers were being used to store maintenance equipment.

 

The Towers of the Brooklyn Bridge

 

The bridge's two suspension towers are 278 feet (85 m) tall, with a footprint of 140 by 59 feet (43 by 18 m) at the high water line.

 

They are built of limestone, granite, and Rosendale cement. The limestone was quarried at the Clark Quarry in Essex County, New York. The granite blocks were quarried and shaped on Vinalhaven Island, Maine, under a contract with the Bodwell Granite Company, and delivered from Maine to New York by schooner.

 

The Manhattan tower contains 46,945 cubic yards (35,892 m3) of masonry, while the Brooklyn tower has 38,214 cubic yards (29,217 m3) of masonry.

 

Each tower contains a pair of Gothic Revival pointed arches, through which the roadways run. The arch openings are 117 feet (36 m) tall and 33.75 feet (10.29 m) wide.

 

The Brooklyn Bridge Caissons

 

The towers rest on underwater caissons made of southern yellow pine. Both caissons contain interior spaces that were used by construction workers. The Manhattan side's caisson is slightly larger, measuring 172 by 102 feet (52 by 31 m) and located 78.5 feet (23.9 m) below high water, while the Brooklyn side's caisson measures 168 by 102 feet (51 by 31 m) and is located 44.5 feet (13.6 m) below high water.

 

The caissons were designed to hold at least the weight of the towers which would exert a pressure of 5 short tons per square foot when fully built, but the caissons were over-engineered for safety.

 

During an accident on the Brooklyn side, when air pressure was lost and the partially-built towers dropped full-force down, the caisson sustained an estimated pressure of 23 short tons per square foot with only minor damage. Most of the timber used in the bridge's construction, including in the caissons, came from mills at Gascoigne Bluff on St. Simons Island, Georgia.

 

The Brooklyn side's caisson, which was built first, originally had a height of 9.5 feet (2.9 m) and a ceiling composed of five layers of timber, each layer 1 foot (0.30 m) tall. Ten more layers of timber were later added atop the ceiling, and the entire caisson was wrapped in tin and wood for further protection against flooding.

 

The thickness of the caisson's sides was 8 feet (2.4 m) at both the bottom and the top. The caisson had six chambers: two each for dredging, supply shafts, and airlocks.

 

The caisson on the Manhattan side was slightly different because it had to be installed at a greater depth. To protect against the increased air pressure at that depth, the Manhattan caisson had 22 layers of timber on its roof, seven more than its Brooklyn counterpart had. The Manhattan caisson also had fifty 4-inch (10 cm)-diameter pipes for sand removal, a fireproof iron-boilerplate interior, and different airlocks and communication systems.

 

History of the Brooklyn Bridge

 

Proposals for a bridge between the then-separate cities of Brooklyn and New York had been suggested as early as 1800. At the time, the only travel between the two cities was by a number of ferry lines.

 

Engineers presented various designs, such as chain or link bridges, though these were never built because of the difficulties of constructing a high enough fixed-span bridge across the extremely busy East River.

 

There were also proposals for tunnels under the East River, but these were considered prohibitively expensive. The current Brooklyn Bridge was conceived by German immigrant John Augustus Roebling in 1852.

 

He had previously designed and constructed shorter suspension bridges, such as Roebling's Delaware Aqueduct in Lackawaxen, Pennsylvania, and the John A. Roebling Suspension Bridge between Cincinnati, Ohio, and Covington, Kentucky.

 

In February 1867, the New York State Senate passed a bill that allowed the construction of a suspension bridge from Brooklyn to Manhattan.

 

Two months later, the New York and Brooklyn Bridge Company was incorporated. There were twenty trustees in total: eight each appointed by the mayors of New York and Brooklyn, as well as the mayors of each city and the auditor and comptroller of Brooklyn.

 

The company was tasked with constructing what was then known as the New York and Brooklyn Bridge. Alternatively, the span was just referred to as the "Brooklyn Bridge", a name originating in a 25th. January 1867 letter to the editor of the Brooklyn Daily Eagle.

 

The act of incorporation, which became law on the 16th. April 1867, authorized the cities of New York (now Manhattan) and Brooklyn to subscribe to $5 million in capital stock, which would fund the bridge's construction.

 

Roebling was subsequently named as the main engineer of the work, and by September 1867, he had presented a master plan of a bridge that would be longer and taller than any suspension bridge previously built.

 

It would incorporate roadways and elevated rail tracks, whose tolls and fares would provide the means to pay for the bridge's construction. It would also include a raised promenade that served as a leisurely pathway.

 

The proposal received much acclaim in both cities, and residents predicted that the New York and Brooklyn Bridge's opening would have as much of an impact as the Suez Canal, the first transatlantic telegraph cable, or the first transcontinental railroad.

 

By early 1869, however, some individuals started to criticize the project, saying either that the bridge was too expensive, or that the construction process was too difficult.

 

To allay concerns about the design of the New York and Brooklyn Bridge, Roebling set up a "Bridge Party" in March 1869, where he invited engineers and members of U.S. Congress to see his other spans. Following the bridge party in April, Roebling and several engineers conducted final surveys.

 

During these surveys, it was determined that the main span would have to be raised from 130 to 135 feet (40 to 41 m), requiring several changes to the overall design.

 

In June 1869, while conducting these surveys, Roebling sustained a crush injury to his foot when a ferry pinned it against a piling. After amputation of his crushed toes, he developed a tetanus infection that left him incapacitated and resulted in his death the following month.

 

Washington Roebling, John Roebling's 32-year-old son, was then hired to fill his father's role. When the younger Roebling was hired, Tammany Hall leader William M. Tweed also became involved in the bridge's construction because, as a major landowner in New York City, he had an interest in the project's completion.

 

The New York and Brooklyn Bridge Company - later known simply as the New York Bridge Company - was actually overseen by Tammany Hall, and it approved Roebling's plans and designated him as chief engineer of the project.

 

Construction of the Brooklyn Bridge

 

The Caissons

 

Construction of the Brooklyn Bridge began on the 2nd. January 2, 1870. The first work entailed the construction of two caissons, upon which the suspension towers would be built.

 

A caisson is a large watertight chamber, open at the bottom, from which the water is kept out by air pressure and in which construction work may be carried out under water.

 

The Brooklyn side's caisson was built at the Webb & Bell shipyard in Greenpoint, Brooklyn, and was launched into the river on the 19th. March 1870. Compressed air was pumped into the caisson, and workers entered the space to dig the sediment until it sank to the bedrock. As one sixteen-year-old from Ireland, Frank Harris, described the fearful experience:

 

"The six of us were working naked to the waist

in the small iron chamber with the temperature

of about 80 degrees Fahrenheit.

In five minutes the sweat was pouring from us,

and all the while we were standing in icy water

that was only kept from rising by the terrific

pressure. No wonder the headaches were

blinding."

 

Once the caisson had reached the desired depth, it was to be filled in with vertical brick piers and concrete. However, due to the unexpectedly high concentration of large boulders on the riverbed, the Brooklyn caisson took several months to sink to the desired depth.

 

Furthermore, in December 1870, its timber roof caught fire, delaying construction further. The "Great Blowout", as the fire was called, delayed construction for several months, since the holes in the caisson had to be repaired.

 

On the 6th. March 1871, the repairs were finished, and the caisson had reached its final depth of 44.5 feet (13.6 m); it was filled with concrete five days later. Overall, about 264 individuals were estimated to have worked in the caisson every day, but because of high worker turnover, the final total was thought to be about 2,500 men.

 

In spite of this, only a few workers were paralyzed. At its final depth, the caisson's air pressure was 21 pounds per square inch. Normal air pressure is 14.7 psi.

 

The Manhattan side's caisson was the next structure to be built. To ensure that it would not catch fire like its counterpart had, the Manhattan caisson was lined with fireproof plate iron.

 

It was launched from Webb & Bell's shipyard on the 11th. May 1871, and maneuvered into place that September.

 

Due to the extreme underwater air pressure inside the much deeper Manhattan caisson, many workers became sick with "the bends" - decompression sickness - during this work, despite the incorporation of airlocks (which were believed to help with decompression sickness at the time).

 

This condition was unknown at the time, and was first called "caisson disease" by the project physician, Andrew Smith. Between the 25th. January and the 31st. May 1872, Smith treated 110 cases of decompression sickness, while three workers died from the condition.

 

When iron probes underneath the Manhattan caisson found the bedrock to be even deeper than expected, Washington Roebling halted construction due to the increased risk of decompression sickness.

 

After the Manhattan caisson reached a depth of 78.5 feet (23.9 m) with an air pressure of 35 pounds per square inch, Washington deemed the sandy subsoil overlying the bedrock 30 feet (9.1 m) beneath to be sufficiently firm, and subsequently infilled the caisson with concrete in July 1872.

 

Washington Roebling himself suffered a paralyzing injury as a result of caisson disease shortly after ground was broken for the Brooklyn tower foundation.

 

His debilitating condition left him unable to supervise the construction in person, so he designed the caissons and other equipment from his apartment, directing the completion of the bridge through a telescope in his bedroom.

 

His wife, Emily Warren Roebling, not only provided written communications between her husband and the engineers on site, but also understood mathematics, calculations of catenary curves, strengths of materials, bridge specifications, and the intricacies of cable construction.

 

She spent the next 11 years helping supervise the bridge's construction, taking over much of the chief engineer's duties, including day-to-day supervision and project management.

 

The Towers of the Brooklyn Bridge

 

After the caissons were completed, piers were constructed on top of each of them upon which masonry towers would be built. The towers' construction was a complex process that took four years.

 

Since the masonry blocks were heavy, the builders transported them to the base of the towers using a pulley system with a continuous 1.5-inch (3.8 cm)-diameter steel wire rope, operated by steam engines at ground level.

 

The blocks were then carried up on a timber track alongside each tower and maneuvered into the proper position using a derrick atop the towers. The blocks sometimes vibrated the ropes because of their weight, but only once did a block fall.

 

Construction of the suspension towers started in mid-1872, and by the time work was halted for the winter in late 1872, parts of each tower had already been built. By mid-1873, there was substantial progress on the towers' construction.

 

The arches of the Brooklyn tower were completed by August 1874. The tower was substantially finished by December 1874, with the erection of saddle plates for the main cables at the top of the tower.

 

The last stone on the Brooklyn tower was raised in June 1875, and the Manhattan tower was completed in July 1876.

 

The work was dangerous: by 1876, three workers had died having fallen from the towers, while nine other workers were killed in other accidents.

 

By 1875, while the towers were being constructed, the project had depleted its original $5 million budget. Two bridge commissioners, one each from Brooklyn and Manhattan, petitioned New York state lawmakers to allot another $8 million for construction. Legislators authorized the money on condition that the cities would buy the stock of Brooklyn Bridge's private stockholders.

 

Work proceeded concurrently on the anchorages on each side. The Brooklyn anchorage broke ground in January 1873 and was substantially completed by August 1875.

 

The Manhattan anchorage was built in less time. Having started in May 1875, it was mostly completed by July 1876. The anchorages could not be fully completed until the main cables were spun, at which point another 6 feet (1.8 m) would be added to the height of each 80-foot (24 m) anchorage.

 

The Brooklyn Bridge Cables

 

The first temporary wire was stretched between the towers on the 15th. August 1876, using chrome steel provided by the Chrome Steel Company of Brooklyn. The wire was then stretched back across the river, and the two ends were spliced to form a traveler, a lengthy loop of wire connecting the towers, which was driven by a 30 horsepower (22 kW) steam hoisting engine at ground level.

 

The wire was one of two that were used to create a temporary footbridge for workers while cable spinning was ongoing. The next step was to send an engineer across the completed traveler wire in a boatswain's chair slung from the wire, to ensure it was safe enough.

 

The bridge's master mechanic, E. F. Farrington, was volunteered for this task, and an estimated crowd of 10,000 people on both shores watched him cross.

 

A second traveler wire was then stretched across the span. The temporary footbridge, located some 60 feet (18 m) above the elevation of the future deck, was completed in February 1877.

 

By December 1876, a steel contract for the permanent cables still had not been awarded. There was disagreement over whether the bridge's cables should use the as-yet-untested Bessemer steel, or the well-proven crucible steel.

 

Until a permanent contract was awarded, the builders ordered 30 short tons of wire in the interim, 10 tons each from three companies, including Washington Roebling's own steel mill in Brooklyn.

 

In the end, it was decided to use number 8 Birmingham gauge (approximately 4 mm or 0.165 inches in diameter) crucible steel, and a request for bids was distributed, to which eight companies responded.

 

In January 1877, a contract for crucible steel was awarded to J. Lloyd Haigh, who was associated with bridge trustee Abram Hewitt, whom Roebling distrusted.

 

The spinning of the wires required the manufacture of large coils of it which were galvanized but not oiled when they left the factory. The coils were delivered to a yard near the Brooklyn anchorage. There they were dipped in linseed oil, hoisted to the top of the anchorage, dried out and spliced into a single wire, and finally coated with red zinc for further galvanizing.

 

There were thirty-two drums at the anchorage yard, eight for each of the four main cables. Each drum had a capacity of 60,000 feet (18,000 m) of wire. The first experimental wire for the main cables was stretched between the towers on the 29th. May 29 1877, and spinning began two weeks later.

 

All four main cables had been strung by that July. During that time, the temporary footbridge was unofficially opened to members of the public, who could receive a visitor's pass; by August 1877 several thousand visitors from around the world had used the footbridge. The visitor passes ceased that September after a visitor had an epileptic seizure and nearly fell off.

 

As the wires were being spun, work also commenced on the demolition of buildings on either side of the river for the Brooklyn Bridge's approaches; this work was mostly complete by September 1877. The following month, initial contracts were awarded for the suspender wires, which would hang down from the main cables and support the deck. By May 1878, the main cables were more than two-thirds complete.

 

However, the following month, one of the wires slipped, killing two people and injuring three others. In 1877, Hewitt wrote a letter urging against the use of Bessemer steel in the bridge's construction. Bids had been submitted for both crucible steel and Bessemer steel; John A. Roebling's Sons submitted the lowest bid for Bessemer steel, but at Hewitt's direction, the contract was awarded to Haigh.

 

A subsequent investigation discovered that Haigh had substituted inferior quality wire in the cables. Of eighty rings of wire that were tested, only five met standards, and it was estimated that Haigh had earned $300,000 from the deception.

 

At this point, it was too late to replace the cables that had already been constructed. Roebling determined that the poorer wire would leave the bridge only four times as strong as necessary, rather than six to eight times as strong. The inferior-quality wire was allowed to remain, and 150 extra wires were added to each cable.

 

To avoid public controversy, Haigh was not fired, but instead was required to personally pay for higher-quality wire. The contract for the remaining wire was awarded to the John A. Roebling's Sons, and by the 5th. October 1878, the last of the main cables' wires went over the river.

 

After the suspender wires had been placed, workers began erecting steel crossbeams to support the roadway as part of the bridge's overall superstructure. Construction on the bridge's superstructure started in March 1879, but, as with the cables, the trustees initially disagreed on whether the steel superstructure should be made of Bessemer or crucible steel.

 

That July, the trustees decided to award a contract for 500 short tons of Bessemer steel to the Edgemoor Iron Works, based in Philadelphia. The trustees later ordered another 500 short tons of Bessemer steel. However, by February 1880 the steel deliveries had not started.

 

That October, the bridge trustees questioned Edgemoor's president about the delay in steel deliveries. Despite Edgemoor's assurances that the contract would be fulfilled, the deliveries still had not been completed by November 1881.

 

Brooklyn mayor Seth Low, who became part of the board of trustees in 1882, became the chairman of a committee tasked to investigate Edgemoor's failure to fulfill the contract. When questioned, Edgemoor's president stated that the delays were the fault of another contractor, the Cambria Iron Company, who were manufacturing the eyebars for the bridge trusses.

 

Further complicating the situation, Washington Roebling had failed to appear at the trustees' meeting in June 1882, since he had gone to Newport, Rhode Island. After the news media discovered this, most of the newspapers called for Roebling to be fired as chief engineer, except for the Daily State Gazette of Trenton, New Jersey, and the Brooklyn Daily Eagle.

 

Some of the longstanding trustees were willing to vouch for Roebling, since construction progress on the Brooklyn Bridge was still ongoing. However, Roebling's behavior was considered suspect among the younger trustees who had joined the board more recently.

 

Construction progress on the bridge itself was submitted in formal monthly reports to the mayors of New York and Brooklyn. For example, the August 1882 report noted that the month's progress included 114 intermediate cords erected within a week, as well as 72 diagonal stays, 60 posts, and numerous floor beams, bridging trusses, and stay bars.

 

By early 1883, the Brooklyn Bridge was considered mostly completed and was projected to open that June. Contracts for bridge lighting were awarded by February 1883, and a toll scheme was approved that March.

 

Opposition to the Bridge

 

There was substantial opposition to the bridge's construction from shipbuilders and merchants located to the north, who argued that the bridge would not provide sufficient clearance underneath for ships.

 

In May 1876, these groups, led by Abraham Miller, filed a lawsuit in the United States District Court against the cities of New York and Brooklyn.

 

In 1879, an Assembly Sub-Committee on Commerce and Navigation began an investigation into the Brooklyn Bridge. A seaman who had been hired to determine the height of the span, testified to the committee about the difficulties that ship masters would experience in bringing their ships under the bridge when it was completed.

 

Another witness, Edward Wellman Serrell, a civil engineer, said that the calculations of the bridge's assumed strength were incorrect.

 

However the Supreme Court decided in 1883 that the Brooklyn Bridge was a lawful structure.

 

The Opening of the Brooklyn Bridge

 

The Brooklyn Bridge was opened for use on the 24th. May 1883. Thousands of people attended the opening ceremony, and many ships were present in the East River for the occasion. Officially, Emily Warren Roebling was the first to cross the bridge.

 

The bridge opening was also attended by U.S. president Chester A. Arthur and New York mayor Franklin Edson, who crossed the bridge and shook hands with Brooklyn mayor Seth Low at the Brooklyn end. Abram Hewitt gave the principal address:

 

"It is not the work of any one man or of any one

age. It is the result of the study, of the experience,

and of the knowledge of many men in many ages.

It is not merely a creation; it is a growth. It stands

before us today as the sum and epitome of human

knowledge; as the very heir of the ages; as the

latest glory of centuries of patient observation,

profound study and accumulated skill, gained,

step by step, in the never-ending struggle of man

to subdue the forces of nature to his control and use."

 

Although Washington Roebling was unable to attend the ceremony (and rarely visited the site again), he held a celebratory banquet at his house on the day of the bridge opening.

 

Further festivity included a performance by a band, gunfire from ships, and a fireworks display. On that first day, a total of 1,800 vehicles and 150,300 people crossed the span.

 

Less than a week after the Brooklyn Bridge opened, ferry crews reported a sharp drop in patronage, while the bridge's toll operators were processing over a hundred people a minute. However, cross-river ferries continued to operate until 1942.

 

The bridge had cost US$15.5 million in 1883 dollars (about US$436,232,000 in 2021) to build, of which Brooklyn paid two-thirds. The bonds to fund the construction were not paid off until 1956.

 

An estimated 27 men died during the bridge's construction. Until the construction of the nearby Williamsburg Bridge in 1903, the Brooklyn Bridge was the longest suspension bridge in the world, 20% longer than any built previously.

 

At the time of opening, the Brooklyn Bridge was not complete; the proposed public transit across the bridge was still being tested, while the Brooklyn approach was being completed.

 

On the 30th. May 1883, six days after the opening, a woman falling down a stairway at the Brooklyn approach caused a stampede which resulted in at least twelve people being crushed and killed.

 

In subsequent lawsuits, the Brooklyn Bridge Company was acquitted of negligence. However, the company did install emergency phone boxes and additional railings, and the trustees approved a fireproofing plan for the bridge.

 

Public transit service began with the opening of the New York and Brooklyn Bridge Railway, a cable car service, on the 25th. September 1883.

 

On the 17th. May 1884, one of P. T. Barnum's most famous attractions, Jumbo the elephant, led a parade of 21 elephants over the Brooklyn Bridge. This helped to lessen doubts about the bridge's stability while also promoting Barnum's circus.

 

Brooklyn Bridge in the Late 19th. & Early 20th. Centuries

 

Movement across the Brooklyn Bridge increased in the years after it opened; a million people paid to cross in the first six months. The bridge carried 8.5 million people in 1884, its first full year of operation; this number doubled to 17 million in 1885, and again to 34 million in 1889.

 

Many of these people were cable car passengers. Additionally, about 4.5 million pedestrians a year were crossing the bridge for free by 1892.

 

The first proposal to make changes to the bridge was sent in only two and a half years after it opened; Linda Gilbert suggested glass steam-powered elevators and an observatory be added to the bridge and a fee charged for use, which would in part fund the bridge's upkeep and in part fund her prison reform charity.

 

This proposal was considered, but not acted upon. Numerous other proposals were made during the first fifty years of the bridge's life.

 

Trolley tracks were added in the center lanes of both roadways in 1898, allowing trolleys to use the bridge as well.

 

Concerns about the Brooklyn Bridge's safety were raised during the turn of the century. In 1898, traffic backups due to a dead horse caused one of the truss cords to buckle.

 

There were more significant worries after twelve suspender cables snapped in 1901, although a thorough investigation found no other defects.

 

After the 1901 incident, five inspectors were hired to examine the bridge each day, a service that cost $250,000 a year.

 

The Brooklyn Rapid Transit Company, which operated routes across the Brooklyn Bridge, issued a notice in 1905 saying that the bridge had reached its transit capacity.

 

Although a second deck for the Brooklyn Bridge was proposed, it was thought to be infeasible because doing so would overload the bridge's structural capacity.

 

Though tolls had been instituted for carriages and cable-car customers since the bridge's opening, pedestrians were spared from the tolls originally. However, by the first decade of the 20th. century, pedestrians were also paying tolls.

 

However tolls on all four bridges across the East River - the Brooklyn Bridge, as well as the Manhattan, Williamsburg, and Queensboro bridges to the north - were abolished in July 1911 as part of a populist policy initiative headed by New York City mayor William Jay Gaynor.

 

Ostensibly in an attempt to reduce traffic on nearby city streets, Grover Whalen, the commissioner of Plant and Structures, banned motor vehicles from the Brooklyn Bridge in 1922. The real reason for the ban was an incident the same year where two cables slipped due to high traffic loads.

 

Both Whalen and Roebling called for the renovation of the Brooklyn Bridge and the construction of a parallel bridge, although the parallel bridge was never built.

 

Brooklyn Bridge in Mid- to late 20th. Century

 

Upgrades to the Bridge

 

The first major upgrade to the Brooklyn Bridge commenced in 1948, when a contract for redesigning the roadways was awarded to David B. Steinman. The renovation was expected to double the capacity of the bridge's roadways to nearly 6,000 cars per hour, at a projected cost of $7 million.

 

The renovation included the demolition of both the elevated and the trolley tracks on the roadways and the widening of each roadway from two to three lanes, as well as the construction of a new steel-and-concrete floor.

 

In addition, new ramps were added to Adams Street, Cadman Plaza, and the Brooklyn Queens Expressway (BQE) on the Brooklyn side, and to Park Row on the Manhattan side. The trolley tracks closed in March 1950 to allow for the widening work to occur.

 

During the construction project, one roadway at a time was closed, allowing reduced traffic flows to cross the bridge in one direction only. The widened south roadway was completed in May 1951, followed by the north roadway in October 1953. In addition, defensive barriers were added to the bridge as a safeguard against sabotage.

 

The restoration was finished in May 1954 with the completion of the reconstructed elevated promenade.

 

While the rebuilding of the span was ongoing, a fallout shelter was constructed beneath the Manhattan approach in anticipation of the Cold War. The abandoned space in one of the masonry arches was stocked with emergency survival supplies for a potential nuclear attack by the Soviet Union; these supplies were still in place half a century later.

 

A repainting of the bridge was announced in advance of its 90th. anniversary.

 

Deterioration and Late-20th. Century Repair

 

The Brooklyn Bridge gradually deteriorated due to age and neglect. While it had 200 full-time dedicated maintenance workers before World War II, that number had dropped to five by the late 20th. century, and the city as a whole only had 160 bridge maintenance workers.

 

In 1974, heavy vehicles such as vans and buses were banned from the bridge to prevent further erosion of the concrete roadway. A report in The New York Times four years later noted that the cables were visibly fraying, and that the pedestrian promenade had holes in it.

 

The city began planning to replace all the Brooklyn Bridge's cables at a cost of $115 million, as part of a larger project to renovate all four toll-free East River spans.

 

By 1980, the Brooklyn Bridge was in such dire condition that it faced imminent closure. In some places, half of the strands in the cables were broken.

 

In June 1981, two of the diagonal stay cables snapped, seriously injuring a pedestrian who later died. Subsequently, the anchorages were found to have developed rust, and an emergency cable repair was necessitated less than a month later after another cable developed slack.

 

Following the incident, the city accelerated the timetable of its proposed cable replacement, and it commenced a $153 million rehabilitation of the Brooklyn Bridge in advance of the 100th anniversary.

 

As part of the project, the bridge's original suspender cables installed by J. Lloyd Haigh were replaced by Bethlehem Steel in 1986, marking the cables' first replacement since construction. In a smaller project, the bridge was floodlit at night, starting in 1982 to highlight its architectural features.

 

Additional problems persisted, and in 1993, high levels of lead were discovered near the bridge's towers. Further emergency repairs were undertaken in mid-1999 after small concrete shards began falling from the bridge into the East River. The concrete deck had been installed during the 1950's renovations, and had a lifespan of about 60 years.

 

Brooklyn Bridge in the 21st. Century

 

The Park Row exit from the bridge's westbound lanes was closed as a safety measure after the September 11, 2001, attacks on the nearby World Trade Center. That section of Park Row was closed since it ran right underneath 1 Police Plaza, the headquarters of the New York City Police Department.

 

In early 2003, to save money on electricity, the bridge's "necklace lights" were turned off at night. They were turned back on later that year after several private entities made donations to fund the lights.

 

After the 2007 collapse of the I-35W bridge in Minneapolis, public attention focused on the condition of bridges across the U.S. The New York Times reported that the Brooklyn Bridge approach ramps had received a "poor" rating during an inspection in 2007.

 

However, a NYCDOT spokesman said that the poor rating did not indicate a dangerous state but rather implied it required renovation. In 2010, the NYCDOT began renovating the approaches and deck, as well as repainting the suspension span.

 

Work included widening two approach ramps from one to two lanes by re-striping a new prefabricated ramp; seismic retrofitting; replacement of rusted railings and safety barriers; and road deck resurfacing. The work necessitated detours for four years.

 

At the time, the project was scheduled to be completed in 2014, but completion was later delayed to 2015, then again to 2017. The project's cost also increased from $508 million in 2010 to $811 million in 2016.

 

In August 2016, after the renovation had been completed, the NYCDOT announced that it would conduct a seven-month, $370,000 study to verify if the bridge could support a heavier upper deck that consisted of an expanded bicycle and pedestrian path.

 

As of 2016, about 10,000 pedestrians and 3,500 cyclists used the pathway on an average weekday. Work on the pedestrian entrance on the Brooklyn side was underway by 2017.

 

The NYCDOT also indicated in 2016 that it planned to reinforce the Brooklyn Bridge's foundations to prevent it from sinking, as well as repair the masonry arches on the approach ramps, which had been damaged by Hurricane Sandy in 2012.

 

In July 2018, the New York City Landmarks Preservation Commission approved a further renovation of the Brooklyn Bridge's suspension towers and approach ramps. That December, the federal government gave the city $25 million in funding, which would contribute to a $337 million rehabilitation of the bridge approaches and the suspension towers. Work started in late 2019 and was scheduled to be completed in 2023.

 

Usage of the Brooklyn Bridge

 

Horse-drawn carriages have been allowed to use the Brooklyn Bridge's roadways since its opening. Originally, each of the two roadways carried two lanes of a different direction of traffic. The lanes were relatively narrow at only 8 feet (2.4 m) wide. In 1922, motor vehicles were banned from the bridge, while horse-drawn carriages were restricted from the Manhattan Bridge. Thereafter, the only vehicles allowed on the Brooklyn Bridge were horse-drawn.

 

By 1950, the main roadway carried six lanes of automobile traffic, three in each direction. It was then reduced to five lanes with the addition of a two-way bike lane on the Manhattan-bound side in 2021.

 

Because of the roadway's height (11 ft (3.4 m)) and weight (6,000 lb (2,700 kg)) restrictions, commercial vehicles and buses are prohibited from using the Brooklyn Bridge.

 

The weight restrictions prohibit heavy passenger vehicles such as pickup trucks and SUVs from using the bridge, though this is not often enforced in practice.

 

Formerly, rail traffic operated on the Brooklyn Bridge as well. Cable cars and elevated railroads used the bridge until 1944, while trolleys ran until 1950.

 

A cable car service began operating on the 25th. September 1883; it ran on the inner lanes of the bridge, between terminals at the Manhattan and Brooklyn ends.

 

Since Washington Roebling believed that steam locomotives would put excessive loads upon the structure of the Brooklyn Bridge, the cable car line was designed as a steam/cable-hauled hybrid.

 

They were powered from a generating station under the Brooklyn approach. The cable cars could not only regulate their speed on the 3.75% upward and downward approaches, but also maintain a constant interval between each other. There were 24 cable cars in total.

 

Initially, the service ran with single-car trains, but patronage soon grew so much that by October 1883, two-car trains were in use. The line carried three million people in the first six months, nine million in 1884, and nearly 20 million in 1885.

 

Patronage continued to increase, and in 1888, the tracks were lengthened and even more cars were constructed to allow for four-car cable car trains. Electric wires for the trolleys were added by 1895, allowing for the potential future decommissioning of the steam/cable system.

 

The terminals were rebuilt once more in July 1895, and, following the implementation of new electric cars in late 1896, the steam engines were dismantled and sold.

 

The Brooklyn Bridge Walkway

 

The Brooklyn Bridge has an elevated promenade open to pedestrians in the center of the bridge, located 18 feet (5.5 m) above the automobile lanes.

 

The path is generally 10 to 17 feet (3.0 to 5.2 m) wide, though this is constrained by obstacles such as protruding cables, benches, and stairways, which create "pinch points" at certain locations. The path narrows to 10 feet (3.0 m) at the locations where the main cables descend to the level of the promenade.

 

Further exacerbating the situation, these "pinch points" are some of the most popular places to take pictures. As a result, in 2016, the NYCDOT announced that it planned to double the promenade's width.

 

On the 14th. September 2021, the DOT closed off the inner-most car lane on the Manhattan-bound side with protective barriers and fencing to create a new bike path. Cyclists are now prohibited from the upper pedestrian lane.

 

Emergency Use of Brooklyn Bridge

 

While the bridge has always permitted the passage of pedestrians, the promenade facilitates movement when other means of crossing the East River have become unavailable.

 

During transit strikes by the Transport Workers Union in 1980 and 2005, people commuting to work used the bridge; they were joined by Mayors Ed Koch and Michael Bloomberg, who crossed as a gesture to the affected public.

 

Pedestrians also walked across the bridge as an alternative to suspended subway services following the 1965, 1977, and 2003 blackouts, and after the September 11 attacks on the World Trade Center.

 

During the 2003 blackouts, many crossing the bridge reported a swaying motion. The higher-than-usual pedestrian load caused this swaying, which was amplified by the tendency of pedestrians to synchronize their footfalls with a sway.

 

Several engineers expressed concern about how this would affect the bridge, although others noted that the bridge did withstand the event and that the redundancies in its design - the inclusion of the three support systems (suspension system, diagonal stay system, and stiffening truss) - make it probably the best secured bridge against such movements going out of control.

 

In designing the bridge, John Roebling had stated that the bridge would sag but not fall, even if one of these structural systems were to fail altogether.

 

Stunts Associated With Brooklyn Bridge

 

There have been several notable jumpers from the Brooklyn Bridge:

 

-- The first person was Robert Emmet Odlum, brother of women's rights activist Charlotte Odlum Smith, on the 19th. May 1885. He struck the water at an angle, and died shortly afterwards from internal injuries.

 

-- Steve Brodie supposedly dropped from underneath the bridge in July 1886 and was briefly arrested for it, although there is some doubt about whether he actually jumped.

 

-- Larry Donovan made a slightly higher jump from the railing a month afterward.

 

Other notable events have taken place on or near the bridge:

 

-- In 1919, Giorgio Pessi piloted what was then one of the world's largest airplanes, the Caproni Ca.5, under the bridge.

 

-- At 9:00 a.m. on the 19th. May 1977, artist Jack Bashkow climbed one of the towers for 'Bridging', which was termed a "media sculpture" by the performance group Art Corporation of America Inc.

 

Seven artists climbed the largest bridges connected to Manhattan in order to:

 

"Replace violence and fear

in mass media for one day".

 

When each of the artists had reached the tops of the bridges, they ignited bright-yellow flares at the same moment, resulting in rush hour traffic disruption, media attention, and the arrest of the climbers, though the charges were later dropped.

 

Called "The first social-sculpture to use mass-media as art” by conceptual artist Joseph Beuys, the event was on the cover of the New York Post, it received international attention, and received ABC Eyewitness News' 1977 Best News of the Year award.

 

John Halpern documented the incident in the film 'Bridging' (1977)

 

-- Halpern attempted another "Bridging" "social sculpture" in 1979, when he planted a radio receiver, gunpowder and fireworks in a bucket atop one of the Brooklyn Bridge towers.

 

The piece was later discovered by police, leading to his arrest for possessing a bomb.

 

-- In 1993, bridge jumper Thierry Devaux illegally performed eight acrobatic bungee jumps above the East River close to the Brooklyn tower.

 

-- On the 1st. October 2011, more than 700 protesters with the Occupy Wall Street movement were arrested while attempting to march across the bridge on the roadway.

 

Protesters disputed the police account of the event, and claimed that the arrests were the result of being trapped on the bridge by the NYPD. The majority of the arrests were subsequently dismissed.

 

-- On the 22nd. July 2014, the two American flags on the flagpoles atop each tower were found to have been replaced by bleached-white American flags.

 

Initially, cannabis activism was suspected as a motive, but on the 12th. August 2014, two Berlin artists claimed responsibility for hoisting the two white flags, having switched the original flags with their replicas.

 

The artists said that the flags were meant to celebrate the beauty of public space and the anniversary of the death of German-born John Roebling, and they denied that it was an anti-American statement.

 

Brooklyn Bridge as a Suicide Spot

 

The first person to jump from the bridge with the intention of suicide was Francis McCarey in 1892.

 

A lesser-known early jumper was James Duffy of County Cavan, Ireland, who on the 15th. April 1895 asked several men to watch him jump from the bridge. Duffy jumped and was not seen again.

 

Additionally, the cartoonist Otto Eppers jumped and survived in 1910, and was then tried and acquitted for attempted suicide.

 

The Brooklyn Bridge has since developed a reputation as a suicide bridge due to the number of jumpers who do so intending to kill themselves, though exact statistics are difficult to find.

 

Crimes and Terrorism Associated With Brooklyn Bridge

 

-- In 1979, police disarmed a stick of dynamite placed under the Brooklyn approach, and an artist in Manhattan was later arrested for the act.

 

-- On the 1st. March 1994, Lebanese-born Rashid Baz opened fire on a van carrying members of the Chabad-Lubavitch Orthodox Jewish Movement, striking 16-year-old student Ari Halberstam and three others traveling on the bridge.

 

Halberstam died five days later from his wounds, and Baz was later convicted of murder. He was apparently acting out of revenge for the Hebron massacre of Palestinian Muslims a few days prior to the incident.

 

After initially classifying the killing as one committed out of road rage, the Justice Department reclassified the case in 2000 as a terrorist attack.

 

The entrance ramp to the bridge on the Manhattan side was subsequently dedicated as the Ari Halberstam Memorial Ramp.

 

-- In 2003, truck driver Lyman Faris was sentenced to 20 years in prison for providing material support to Al-Qaeda, after an earlier plot to destroy the bridge by cutting through its support wires with blowtorches was thwarted.

 

Brooklyn Bridge Anniversary Celebrations

 

-- The 50th.-anniversary celebrations on the 24th. May 1933 included a ceremony featuring an airplane show, ships, and fireworks, as well as a banquet.

 

-- During the centennial celebrations on the 24th. May 1983, President Ronald Reagan led a cavalcade of cars across the bridge.

 

A flotilla of ships visited the harbor, officials held parades, and Grucci Fireworks held a fireworks display that evening.

 

For the centennial, the Brooklyn Museum exhibited a selection of the original drawings made for the bridge.

 

Culture

 

The Brooklyn Bridge has had an impact on idiomatic American English. For example, references to "Selling the Brooklyn Bridge" abound in American culture, sometimes as examples of rural gullibility, but more often in connection with an idea that strains credulity.

 

George C. Parker and William McCloundy were two early 20th.-century con men who may have perpetrated this scam successfully on unwitting tourists, although the author of 'The Brooklyn Bridge: A Cultural History' wrote:

 

"No evidence exists that the bridge

has ever been sold to a 'gullible

outlander'".

 

However, anyone taken in by fraudsters is hardly likely to publicize the fact.

 

A popular tradition on Brooklyn Bridge is for couples to inscribe a date and their initials onto a padlock, attach it to the bridge, and throw the key into the water as a sign of their love.

 

The practice of attaching 'love locks' to the bridge is officially illegal in New York City, and in theory the NYPD can give violators a $100 fine.

 

NYCDOT workers periodically remove the love locks from the bridge at a cost of $100,000 per year.

 

Brooklyn Bridge in the Media

 

The bridge is often featured in wide shots of the New York City skyline in television and film, and has been depicted in numerous works of art.

 

Fictional works have used the Brooklyn Bridge as a setting; for instance, the dedication of a portion of the bridge, and the bridge itself, were key components in the 2001 film Kate & Leopold.

 

Furthermore, the Brooklyn Bridge has also served as an icon of America, with mentions in numerous songs, books, and poems.

 

Among the most notable of these works is that of American Modernist poet Hart Crane, who used the Brooklyn Bridge as a central metaphor and organizing structure for his second book of poetry, 'The Bridge' (1930).

 

The Brooklyn Bridge has also been lauded for its architecture. One of the first positive reviews was "The Bridge as a Monument", a Harper's Weekly piece written by architecture critic Montgomery Schuyler and published a week after the bridge's opening.

 

In the piece, Schuyler wrote:

 

"It so happens that the work which is likely to be

our most durable monument, and to convey some

knowledge of us to the most remote posterity, is a

work of bare utility; not a shrine, not a fortress, not

a palace, but a bridge."

 

Architecture critic Lewis Mumford cited the piece as the impetus for serious architectural criticism in the U.S. He wrote that in the 1920's the bridge was a source of joy and inspiration in his childhood, and that it was a profound influence in his adolescence.

 

Later critics regarded the Brooklyn Bridge as a work of art, as opposed to an engineering feat or a means of transport.

 

Not all critics appreciated the bridge, however. Henry James, writing in the early 20th. century, cited the bridge as an ominous symbol of the city's transformation into a "steel-souled machine room".

 

The construction of the Brooklyn Bridge is detailed in numerous media sources, including David McCullough's 1972 book 'The Great Bridge', and Ken Burns's 1981 documentary 'Brooklyn Bridge'.

 

It is also described in 'Seven Wonders of the Industrial World', a BBC docudrama series with an accompanying book, as well as in 'Chief Engineer: Washington Roebling, The Man Who Built the Brooklyn Bridge', a biography published in 2017.

The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the longest suspension bridge in the world at the time of its opening, with a main span of 1,595.5 feet (486.3 m) and a deck 127 ft (38.7 m) above mean high water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915.

 

Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century, which eventually led to the construction of the current span, designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling. Construction started in 1870, with the Tammany Hall-controlled New York Bridge Company overseeing construction, although numerous controversies and the novelty of the design prolonged the project over thirteen years. Since opening, the Brooklyn Bridge has undergone several reconfigurations, having carried horse-drawn vehicles and elevated railway lines until 1950. To alleviate increasing traffic flows, additional bridges and tunnels were built across the East River. Following gradual deterioration, the Brooklyn Bridge has been renovated several times, including in the 1950s, 1980s, and 2010s.

 

The Brooklyn Bridge is the southernmost of the four toll-free vehicular bridges connecting Manhattan Island and Long Island, with the Manhattan Bridge, the Williamsburg Bridge, and the Queensboro Bridge to the north. Only passenger vehicles and pedestrian and bicycle traffic are permitted. A major tourist attraction since its opening, the Brooklyn Bridge has become an icon of New York City. Over the years, the bridge has been used as the location of various stunts and performances, as well as several crimes and attacks. The Brooklyn Bridge has been designated a National Historic Landmark, a New York City landmark, and a National Historic Civil Engineering Landmark.

 

The Brooklyn Bridge, an early example of a steel-wire suspension bridge, uses a hybrid cable-stayed/suspension bridge design, with both vertical and diagonal suspender cables. Its stone towers are neo-Gothic, with characteristic pointed arches. The New York City Department of Transportation (NYCDOT), which maintains the bridge, says that its original paint scheme was "Brooklyn Bridge Tan" and "Silver", although a writer for The New York Post states that it was originally entirely "Rawlins Red".

 

To provide sufficient clearance for shipping in the East River, the Brooklyn Bridge incorporates long approach viaducts on either end to raise it from low ground on both shores. Including approaches, the Brooklyn Bridge is a total of 6,016 feet (1,834 m) long when measured between the curbs at Park Row in Manhattan and Sands Street in Brooklyn. A separate measurement of 5,989 feet (1,825 m) is sometimes given; this is the distance from the curb at Centre Street in Manhattan.

 

The main span between the two suspension towers is 1,595.5 feet (486.3 m) long and 85 feet (26 m) wide. The bridge "elongates and contracts between the extremes of temperature from 14 to 16 inches". Navigational clearance is 127 ft (38.7 m) above mean high water (MHW). A 1909 Engineering Magazine article said that, at the center of the span, the height above MHW could fluctuate by more than 9 feet (2.7 m) due to temperature and traffic loads, while more rigid spans had a lower maximum deflection.

 

The side spans, between each suspension tower and each side's suspension anchorages, are 930 feet (280 m) long. At the time of construction, engineers had not yet discovered the aerodynamics of bridge construction, and bridge designs were not tested in wind tunnels. It was coincidental that the open truss structure supporting the deck is, by its nature, subject to fewer aerodynamic problems. This is because John Roebling designed the Brooklyn Bridge's truss system to be six to eight times as strong as he thought it needed to be. However, due to a supplier's fraudulent substitution of inferior-quality cable in the initial construction, the bridge was reappraised at the time as being only four times as strong as necessary.

 

The main span and side spans are supported by a structure containing six trusses running parallel to the roadway, each of which is 33 feet (10 m) deep. The trusses allow the Brooklyn Bridge to hold a total load of 18,700 short tons (16,700 long tons), a design consideration from when it originally carried heavier elevated trains. These trusses are held up by suspender ropes, which hang downward from each of the four main cables. Crossbeams run between the trusses at the top, and diagonal and vertical stiffening beams run on the outside and inside of each roadway.

 

An elevated pedestrian-only promenade runs in between the two roadways and 18 feet (5.5 m) above them. It typically runs 4 feet (1.2 m) below the level of the crossbeams, except at the areas surrounding each tower. Here, the promenade rises to just above the level of the crossbeams, connecting to a balcony that slightly overhangs the two roadways. The path is generally 10 to 17 feet (3.0 to 5.2 m) wide. The iron railings were produced by Janes & Kirtland, a Bronx iron foundry that also made the United States Capitol dome and the Bow Bridge in Central Park.

 

Each of the side spans is reached by an approach ramp. The 971-foot (296 m) approach ramp from the Brooklyn side is shorter than the 1,567-foot (478 m) approach ramp from the Manhattan side. The approaches are supported by Renaissance-style arches made of masonry; the arch openings themselves were filled with brick walls, with small windows within. The approach ramp contains nine arch or iron-girder bridges across side streets in Manhattan and Brooklyn.

 

Underneath the Manhattan approach, a series of brick slopes or "banks" was developed into a skate park, the Brooklyn Banks, in the late 1980s. The park uses the approach's support pillars as obstacles. In the mid-2010s, the Brooklyn Banks were closed to the public because the area was being used as a storage site during the bridge's renovation. The skateboarding community has attempted to save the banks on multiple occasions; after the city destroyed the smaller banks in the 2000s, the city government agreed to keep the larger banks for skateboarding. When the NYCDOT removed the bricks from the banks in 2020, skateboarders started an online petition.

 

The Brooklyn Bridge contains four main cables, which descend from the tops of the suspension towers and help support the deck. Two are located to the outside of the bridge's roadways, while two are in the median of the roadways. Each main cable measures 15.75 inches (40.0 cm) in diameter and contains 5,282 parallel, galvanized steel wires wrapped closely together in a cylindrical shape. These wires are bundled in 19 individual strands, with 278 wires to a strand. This was the first use of bundling in a suspension bridge and took several months for workers to tie together. Since the 2000s, the main cables have also supported a series of 24-watt LED lighting fixtures, referred to as "necklace lights" due to their shape.

 

In addition, 1,520 galvanized steel wire suspender cables hang downward from the main cables, and another 400 cable stays extend diagonally from the towers. These wires hold up the truss structure around the bridge deck.

 

Each side of the bridge contains an anchorage for the main cables. The anchorages are trapezoidal limestone structures located slightly inland of the shore, measuring 129 by 119 feet (39 by 36 m) at the base and 117 by 104 feet (36 by 32 m) at the top. Each anchorage weighs 60,000 short tons (54,000 long tons; 54,000 t). The Manhattan anchorage rests on a foundation of bedrock while the Brooklyn anchorage rests on clay.

 

The anchorages both have four anchor plates, one for each of the main cables, which are located near ground level and parallel to the ground. The anchor plates measure 16 by 17.5 feet (4.9 by 5.3 m), with a thickness of 2.5 feet (0.76 m) and weigh 46,000 pounds (21,000 kg) each. Each anchor plate is connected to the respective main cable by two sets of nine eyebars, each of which is about 12.5 feet (3.8 m) long and up to 9 by 3 inches (229 by 76 mm) thick. The chains of eyebars curve downward from the cables toward the anchor plates, and the eyebars vary in size depending on their position.

 

The anchorages also contain numerous passageways and compartments. Starting in 1876, in order to fund the bridge's maintenance, the New York City government made the large vaults under the bridge's Manhattan anchorage available for rent, and they were in constant use during the early 20th century. The vaults were used to store wine, as they were kept at a consistent 60 °F (16 °C) temperature due to a lack of air circulation. The Manhattan vault was called the "Blue Grotto" because of a shrine to the Virgin Mary next to an opening at the entrance. The vaults were closed for public use in the late 1910s and 1920s during World War I and Prohibition but were reopened thereafter. When New York magazine visited one of the cellars in 1978, it discovered a "fading inscription" on a wall reading: "Who loveth not wine, women and song, he remaineth a fool his whole life long." Leaks found within the vault's spaces necessitated repairs during the late 1980s and early 1990s. By the late 1990s, the chambers were being used to store maintenance equipment.

 

The towers rest on underwater caissons made of southern yellow pine. Both caissons contain interior spaces that were used by construction workers. The Manhattan side's caisson is slightly larger, measuring 172 by 102 feet (52 by 31 m) and located 78.5 feet (23.9 m) below high water, while the Brooklyn side's caisson measures 168 by 102 feet (51 by 31 m) and is located 44.5 feet (13.6 m) below high water. The caissons were designed to hold at least the weight of the towers which would exert a pressure of 5 short tons per square foot (49 t/m2) when fully built, but the caissons were over-engineered for safety. During an accident on the Brooklyn side, when air pressure was lost and the partially-built towers dropped full-force down, the caisson sustained an estimated pressure of 23 short tons per square foot (220 t/m2) with only minor damage. Most of the timber used in the bridge's construction, including in the caissons, came from mills at Gascoigne Bluff on St. Simons Island, Georgia.

 

The Brooklyn side's caisson, which was built first, originally had a height of 9.5 feet (2.9 m) and a ceiling composed of five layers of timber, each layer 1 foot (0.30 m) tall. Ten more layers of timber were later added atop the ceiling, and the entire caisson was wrapped in tin and wood for further protection against flooding. The thickness of the caisson's sides was 8 feet (2.4 m) at both the bottom and the top. The caisson had six chambers: two each for dredging, supply shafts, and airlocks.

 

The caisson on the Manhattan side was slightly different because it had to be installed at a greater depth. To protect against the increased air pressure at that depth, the Manhattan caisson had 22 layers of timber on its roof, seven more than its Brooklyn counterpart had. The Manhattan caisson also had fifty 4-inch (10 cm)-diameter pipes for sand removal, a fireproof iron-boilerplate interior, and different airlocks and communication systems.

 

New York, often called New York City or simply NYC, is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each of which is coextensive with a respective county. It is a global city and a cultural, financial, high-tech, entertainment, and media center with a significant influence on commerce, health care, scientific output, life sciences, research, technology, education, politics, tourism, dining, art, fashion, and sports. Home to the headquarters of the United Nations, New York is an important center for international diplomacy, and is sometimes described as the world's most important city and the capital of the world.

 

With an estimated population in 2022 of 8,335,897 distributed over 300.46 square miles (778.2 km2), the city is the most densely populated major city in the United States. New York has more than double the population of Los Angeles, the nation's second-most populous city. New York is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the U.S. by both population and urban area. With more than 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York City is one of the world's most populous megacities. The city and its metropolitan area are the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. In 2021, the city was home to nearly 3.1 million residents born outside the U.S., the largest foreign-born population of any city in the world.

 

New York City traces its origins to Fort Amsterdam and a trading post founded on the southern tip of Manhattan Island by Dutch colonists in approximately 1624. The settlement was named New Amsterdam (Dutch: Nieuw Amsterdam) in 1626 and was chartered as a city in 1653. The city came under English control in 1664 and was renamed New York after King Charles II granted the lands to his brother, the Duke of York. The city was temporarily regained by the Dutch in July 1673 and was renamed New Orange; however, the city has been named New York since November 1674. New York City was the capital of the United States from 1785 until 1790. The modern city was formed by the 1898 consolidation of its five boroughs: Manhattan, Brooklyn, Queens, The Bronx, and Staten Island, and has been the largest U.S. city ever since.

 

Anchored by Wall Street in the Financial District of Lower Manhattan, New York City has been called both the world's premier financial and fintech center and the most economically powerful city in the world. As of 2022, the New York metropolitan area is the largest metropolitan economy in the world with a gross metropolitan product of over US$2.16 trillion. If the New York metropolitan area were its own country, it would have the tenth-largest economy in the world. The city is home to the world's two largest stock exchanges by market capitalization of their listed companies: the New York Stock Exchange and Nasdaq. New York City is an established safe haven for global investors. As of 2023, New York City is the most expensive city in the world for expatriates to live. New York City is home to the highest number of billionaires, individuals of ultra-high net worth (greater than US$30 million), and millionaires of any city in the world

 

The written history of New York City began with the first European explorer, the Italian Giovanni da Verrazzano in 1524. European settlement began with the Dutch in 1608 and New Amsterdam was founded in 1624.

 

The "Sons of Liberty" campaigned against British authority in New York City, and the Stamp Act Congress of representatives from throughout the Thirteen Colonies met in the city in 1765 to organize resistance to Crown policies. The city's strategic location and status as a major seaport made it the prime target for British seizure in 1776. General George Washington lost a series of battles from which he narrowly escaped (with the notable exception of the Battle of Harlem Heights, his first victory of the war), and the British Army occupied New York and made it their base on the continent until late 1783, attracting Loyalist refugees.

 

The city served as the national capital under the Articles of Confederation from 1785 to 1789, and briefly served as the new nation's capital in 1789–90 under the United States Constitution. Under the new government, the city hosted the inauguration of George Washington as the first President of the United States, the drafting of the United States Bill of Rights, and the first Supreme Court of the United States. The opening of the Erie Canal gave excellent steamboat connections with upstate New York and the Great Lakes, along with coastal traffic to lower New England, making the city the preeminent port on the Atlantic Ocean. The arrival of rail connections to the north and west in the 1840s and 1850s strengthened its central role.

 

Beginning in the mid-19th century, waves of new immigrants arrived from Europe dramatically changing the composition of the city and serving as workers in the expanding industries. Modern New York traces its development to the consolidation of the five boroughs in 1898 and an economic and building boom following the Great Depression and World War II. Throughout its history, New York has served as a main port of entry for many immigrants, and its cultural and economic influence has made it one of the most important urban areas in the United States and the world. The economy in the 1700s was based on farming, local production, fur trading, and Atlantic jobs like shipbuilding. In the 1700s, New York was sometimes referred to as a breadbasket colony, because one of its major crops was wheat. New York colony also exported other goods included iron ore as a raw material and as manufactured goods such as tools, plows, nails and kitchen items such as kettles, pans and pots.

 

The area that eventually encompassed modern day New York was inhabited by the Lenape people. These groups of culturally and linguistically related Native Americans traditionally spoke an Algonquian language now referred to as Unami. Early European settlers called bands of Lenape by the Unami place name for where they lived, such as "Raritan" in Staten Island and New Jersey, "Canarsee" in Brooklyn, and "Hackensack" in New Jersey across the Hudson River from Lower Manhattan. Some modern place names such as Raritan Bay and Canarsie are derived from Lenape names. Eastern Long Island neighbors were culturally and linguistically more closely related to the Mohegan-Pequot peoples of New England who spoke the Mohegan-Montauk-Narragansett language.

 

These peoples made use of the abundant waterways in the New York region for fishing, hunting trips, trade, and occasionally war. Many paths created by the indigenous peoples are now main thoroughfares, such as Broadway in Manhattan, the Bronx, and Westchester. The Lenape developed sophisticated techniques of hunting and managing their resources. By the time of the arrival of Europeans, they were cultivating fields of vegetation through the slash and burn technique, which extended the productive life of planted fields. They also harvested vast quantities of fish and shellfish from the bay. Historians estimate that at the time of European settlement, approximately 5,000 Lenape lived in 80 settlements around the region.

 

The first European visitor to the area was Giovanni da Verrazzano, an Italian in command of the French ship La Dauphine in 1524. It is believed he sailed into Upper New York Bay, where he encountered native Lenape, returned through the Narrows, where he anchored the night of April 17, and left to continue his voyage. He named the area New Angoulême (La Nouvelle-Angoulême) in honor of Francis I, King of France of the royal house of Valois-Angoulême and who had been Count of Angoulême from 1496 until his coronation in 1515. The name refers to the town of Angoulême, in the Charente département of France. For the next century, the area was occasionally visited by fur traders or explorers, such as by Esteban Gomez in 1525.

 

European exploration continued on September 2, 1609, when the Englishman Henry Hudson, in the employ of the Dutch East India Company, sailed the Half Moon through the Narrows into Upper New York Bay. Like Christopher Columbus, Hudson was looking for a westerly passage to Asia. He never found one, but he did take note of the abundant beaver population. Beaver pelts were in fashion in Europe, fueling a lucrative business. Hudson's report on the regional beaver population served as the impetus for the founding of Dutch trading colonies in the New World. The beaver's importance in New York's history is reflected by its use on the city's official seal.

 

The first Dutch fur trading posts and settlements were in 1614 near present-day Albany, New York, the same year that New Netherland first appeared on maps. Only in May 1624 did the Dutch West India Company land a number of families at Noten Eylant (today's Governors Island) off the southern tip of Manhattan at the mouth of the North River (today's Hudson River). Soon thereafter, most likely in 1626, construction of Fort Amsterdam began. Later, the Dutch West Indies Company imported African slaves to serve as laborers; they were forced to build the wall that defended the town against English and Indian attacks. Early directors included Willem Verhulst and Peter Minuit. Willem Kieft became director in 1638 but five years later was embroiled in Kieft's War against the Native Americans. The Pavonia Massacre, across the Hudson River in present-day Jersey City, resulted in the death of 80 natives in February 1643. Following the massacre, Algonquian tribes joined forces and nearly defeated the Dutch. Holland sent additional forces to the aid of Kieft, leading to the overwhelming defeat of the Native Americans and a peace treaty on August 29, 1645.

 

On May 27, 1647, Peter Stuyvesant was inaugurated as director general upon his arrival and ruled as a member of the Dutch Reformed Church. The colony was granted self-government in 1652, and New Amsterdam was incorporated as a city on February 2, 1653. The first mayors (burgemeesters) of New Amsterdam, Arent van Hattem and Martin Cregier, were appointed in that year. By the early 1660s, the population consisted of approximately 1500 Europeans, only about half of whom were Dutch, and 375 Africans, 300 of whom were slaves.

 

A few of the original Dutch place names have been retained, most notably Flushing (after the Dutch town of Vlissingen), Harlem (after Haarlem), and Brooklyn (after Breukelen). Few buildings, however, remain from the 17th century. The oldest recorded house still in existence in New York, the Pieter Claesen Wyckoff House in Brooklyn, dates from 1652.

 

On August 27, 1664, four English frigates under the command of Col. Richard Nicolls sailed into New Amsterdam's harbor and demanded New Netherland's surrender, as part of an effort by King Charles II's brother James, Duke of York, the Lord High Admiral to provoke the Second Anglo-Dutch War. Two weeks later, Stuyvesant officially capitulated by signing Articles of Surrender and in June 1665, the town was reincorporated under English law and renamed "New York" after the Duke, and Fort Orange was renamed "Fort Albany". The war ended in a Dutch victory in 1667, but the colony remained under English rule as stipulated in the Treaty of Breda. During the Third Anglo-Dutch War, the Dutch briefly recaptured the city in 1673, renaming the city "New Orange", before permanently ceding the colony of New Netherland to England for what is now Suriname in November 1674 at the Treaty of Westminster.

 

The colony benefited from increased immigration from Europe and its population grew faster. The Bolting Act of 1678, whereby no mill outside the city was permitted to grind wheat or corn, boosted growth until its repeal in 1694, increasing the number of houses over the period from 384 to 983.

 

In the context of the Glorious Revolution in England, Jacob Leisler led Leisler's Rebellion and effectively controlled the city and surrounding areas from 1689 to 1691, before being arrested and executed.

 

Lawyers

In New York at first, legal practitioners were full-time businessmen and merchants, with no legal training, who had watched a few court proceedings, and mostly used their own common sense together with snippets they had picked up about English law. Court proceedings were quite informal, for the judges had no more training than the attorneys.

 

By the 1760s, the situation had dramatically changed. Lawyers were essential to the rapidly growing international trade, dealing with questions of partnerships, contracts, and insurance. The sums of money involved were large, and hiring an incompetent lawyer was a very expensive proposition. Lawyers were now professionally trained, and conversant in an extremely complex language that combined highly specific legal terms and motions with a dose of Latin. Court proceedings became a baffling mystery to the ordinary layman. Lawyers became more specialized and built their reputation, and their fee schedule, on the basis of their reputation for success. But as their status, wealth and power rose, animosity grew even faster. By the 1750s and 1760s, there was a widespread attack ridiculing and demeaning the lawyers as pettifoggers (lawyers lacking sound legal skills). Their image and influence declined. The lawyers organized a bar association, but it fell apart in 1768 during the bitter political dispute between the factions based in the Delancey and Livingston families. A large fraction of the prominent lawyers were Loyalists; their clientele was often to royal authority or British merchants and financiers. They were not allowed to practice law unless they took a loyalty oath to the new United States of America. Many went to Britain or Canada (primarily to New Brunswick and Nova Scotia) after losing the war.

 

For the next century, various attempts were made, and failed, to build an effective organization of lawyers. Finally a Bar Association emerged in 1869 that proved successful and continues to operate.

 

By 1700, the Lenape population of New York had diminished to 200. The Dutch West Indies Company transported African slaves to the post as trading laborers used to build the fort and stockade, and some gained freedom under the Dutch. After the seizure of the colony in 1664, the slave trade continued to be legal. In 1703, 42% of the New York households had slaves; they served as domestic servants and laborers but also became involved in skilled trades, shipping and other fields. Yet following reform in ethics according to American Enlightenment thought, by the 1770s slaves made up less than 25% of the population.

 

By the 1740s, 20% of the residents of New York were slaves, totaling about 2,500 people.

 

After a series of fires in 1741, the city panicked over rumors of its black population conspiring with some poor whites to burn the city. Historians believe their alarm was mostly fabrication and fear, but officials rounded up 31 black and 4 white people, who over a period of months were convicted of arson. Of these, the city executed 13 black people by burning them alive and hanged the remainder of those incriminated.

 

The Stamp Act and other British measures fomented dissent, particularly among Sons of Liberty who maintained a long-running skirmish with locally stationed British troops over Liberty Poles from 1766 to 1776. The Stamp Act Congress met in New York City in 1765 in the first organized resistance to British authority across the colonies. After the major defeat of the Continental Army in the Battle of Long Island in late 1776, General George Washington withdrew to Manhattan Island, but with the subsequent defeat at the Battle of Fort Washington the island was effectively left to the British. The city became a haven for loyalist refugees, becoming a British stronghold for the entire war. Consequently, the area also became the focal point for Washington's espionage and intelligence-gathering throughout the war.

 

New York was greatly damaged twice by fires of suspicious origin, with the Loyalists and Patriots accusing each other of starting the conflagration. The city became the political and military center of operations for the British in North America for the remainder of the war. Continental Army officer Nathan Hale was hanged in Manhattan for espionage. In addition, the British began to hold the majority of captured American prisoners of war aboard prison ships in Wallabout Bay, across the East River in Brooklyn. More Americans lost their lives aboard these ships than died in all the battles of the war. The British occupation lasted until November 25, 1783. George Washington triumphantly returned to the city that day, as the last British forces left the city.

 

Starting in 1785 the Congress met in the city of New York under the Articles of Confederation. In 1789, New York became the first national capital under the new Constitution. The Constitution also created the current Congress of the United States, and its first sitting was at Federal Hall on Wall Street. The first Supreme Court sat there. The United States Bill of Rights was drafted and ratified there. George Washington was inaugurated at Federal Hall. New York remained the national capital until 1790, when the role was transferred to Philadelphia.

 

During the 19th century, the city was transformed by immigration, a visionary development proposal called the Commissioners' Plan of 1811 which expanded the city street grid to encompass all of Manhattan, and the opening of the Erie Canal in 1825, which connected the Atlantic port to the vast agricultural markets of the Midwestern United States and Canada. By 1835, New York had surpassed Philadelphia as the largest city in the United States. New York grew as an economic center, first as a result of Alexander Hamilton's policies and practices as the first Secretary of the Treasury.

 

In 1842, water was piped from a reservoir to supply the city for the first time.

 

The Great Irish Famine (1845–1850) brought a large influx of Irish immigrants, and by 1850 the Irish comprised one quarter of the city's population. Government institutions, including the New York City Police Department and the public schools, were established in the 1840s and 1850s to respond to growing demands of residents. In 1831, New York University was founded by U.S. Secretary of the Treasury Albert Gallatin as a non-denominal institution surrounding Washington Square Park.

 

This period started with the 1855 inauguration of Fernando Wood as the first mayor from Tammany Hall. It was the political machine based among Irish Americans that controlled the local Democratic Party. It usually dominated local politics throughout this period and into the 1930s. Public-minded members of the merchant community pressed for a Central Park, which was opened to a design competition in 1857; it became the first landscape park in an American city.

 

During the American Civil War (1861–1865), the city was affected by its history of strong commercial ties to the South; before the war, half of its exports were related to cotton, including textiles from upstate mills. Together with its growing immigrant population, which was angry about conscription, sympathies among residents were divided for both the Union and Confederacy at the outbreak of war. Tensions related to the war culminated in the Draft Riots of 1863 led by Irish Catholics, who attacked black neighborhood and abolitionist homes. Many blacks left the city and moved to Brooklyn. After the Civil War, the rate of immigration from Europe grew steeply, and New York became the first stop for millions seeking a new and better life in the United States, a role acknowledged by the dedication of the Statue of Liberty in 1886.

 

From 1890 to 1930, the largest cities, led by New York, were the focus of international attention. The skyscrapers and tourist attractions were widely publicized. Suburbs were emerging as bedroom communities for commuters to the central city. San Francisco dominated the West, Atlanta dominated the South, Boston dominated New England; Chicago dominated the Midwest United States. New York City dominated the entire nation in terms of communications, trade, finance, popular culture, and high culture. More than a fourth of the 300 largest corporations in 1920 were headquartered here.

 

In 1898, the modern City of New York was formed with the consolidation of Brooklyn (until then an independent city), Manhattan, and outlying areas. Manhattan and the Bronx were established as two separate boroughs and joined with three other boroughs created from parts of adjacent counties to form the new municipal government originally called "Greater New York". The Borough of Brooklyn incorporated the independent City of Brooklyn, recently joined to Manhattan by the Brooklyn Bridge; the Borough of Queens was created from western Queens County (with the remnant established as Nassau County in 1899); and the Borough of Richmond contained all of Richmond County. Municipal governments contained within the boroughs were abolished, and the county governmental functions were absorbed by the city or each borough. In 1914, the New York State Legislature created Bronx County, making five counties coterminous with the five boroughs.

 

The Bronx had a steady boom period during 1898–1929, with a population growth by a factor of six from 200,000 in 1900 to 1.3 million in 1930. The Great Depression created a surge of unemployment, especially among the working class, and a slow-down of growth.

 

On June 15, 1904, over 1,000 people, mostly German immigrant women and children, were killed when the excursion steamship General Slocum caught fire and sank. It is the city's worst maritime disaster. On March 25, 1911, the Triangle Shirtwaist Factory fire in Greenwich Village took the lives of 146 garment workers. In response, the city made great advancements in the fire department, building codes, and workplace regulations.

 

Throughout the first half of the 20th century, the city became a world center for industry, commerce, and communication, marking its rising influence with such events as the Hudson-Fulton Celebration of 1909. Interborough Rapid Transit (the first New York City Subway company) began operating in 1904, and the railroads operating out of Grand Central Terminal and Pennsylvania Station thrived.

 

From 1918 to 1920, New York City was affected by the largest rent strike wave in its history. Somewhere between several 10,000's and 100,000's of tenants struck across the city. A WW1 housing and coal shortage sparked the strikes. It became marked both by occasional violent scuffles and the Red Scare.  It would lead to the passage of the first rent laws in the nations history.

 

The city was a destination for internal migrants as well as immigrants. Through 1940, New York was a major destination for African Americans during the Great Migration from the rural American South. The Harlem Renaissance flourished during the 1920s and the era of Prohibition. New York's ever accelerating changes and rising crime and poverty rates were reduced after World War I disrupted trade routes, the Immigration Restriction Acts limited additional immigration after the war, and the Great Depression reduced the need for new labor. The combination ended the rule of the Gilded Age barons. As the city's demographics temporarily stabilized, labor unionization helped the working class gain new protections and middle-class affluence, the city's government and infrastructure underwent a dramatic overhaul under Fiorello La Guardia, and his controversial parks commissioner, Robert Moses, ended the blight of many tenement areas, expanded new parks, remade streets, and restricted and reorganized zoning controls.

 

For a while, New York ranked as the most populous city in the world, overtaking London in 1925, which had reigned for a century.[58] During the difficult years of the Great Depression, the reformer Fiorello La Guardia was elected as mayor, and Tammany Hall fell after eighty years of political dominance.

 

Despite the effects of the Great Depression, some of the world's tallest skyscrapers were built during the 1930s. Art Deco architecture—such as the iconic Chrysler Building, Empire State Building, and 30 Rockefeller Plaza— came to define the city's skyline. The construction of the Rockefeller Center occurred in the 1930s and was the largest-ever private development project at the time. Both before and especially after World War II, vast areas of the city were also reshaped by the construction of bridges, parks and parkways coordinated by Robert Moses, the greatest proponent of automobile-centered modernist urbanism in America.

 

Returning World War II veterans and immigrants from Europe created a postwar economic boom. Demands for new housing were aided by the G.I. Bill for veterans, stimulating the development of huge suburban tracts in eastern Queens and Nassau County. The city was extensively photographed during the post–war years by photographer Todd Webb.

 

New York emerged from the war as the leading city of the world, with Wall Street leading the United States ascendancy. In 1951, the United Nations relocated from its first headquarters in Flushing Meadows Park, Queens, to the East Side of Manhattan. During the late 1960s, the views of real estate developer and city leader Robert Moses began to fall out of favor as the anti-urban renewal views of Jane Jacobs gained popularity. Citizen rebellion stopped a plan to construct an expressway through Lower Manhattan.

 

After a short war boom, the Bronx declined from 1950 to 1985, going from predominantly moderate-income to mostly lower-income, with high rates of violent crime and poverty. The Bronx has experienced an economic and developmental resurgence starting in the late 1980s that continues into today.

 

The transition away from the industrial base toward a service economy picked up speed, while the jobs in the large shipbuilding and garment industries declined sharply. The ports converted to container ships, costing many traditional jobs among longshoremen. Many large corporations moved their headquarters to the suburbs or to distant cities. At the same time, there was enormous growth in services, especially finance, education, medicine, tourism, communications and law. New York remained the largest city and largest metropolitan area in the United States, and continued as its largest financial, commercial, information, and cultural center.

 

Like many major U.S. cities, New York suffered race riots, gang wars and some population decline in the late 1960s. Street activists and minority groups such as the Black Panthers and Young Lords organized rent strikes and garbage offensives, demanding improved city services for poor areas. They also set up free health clinics and other programs, as a guide for organizing and gaining "Power to the People." By the 1970s the city had gained a reputation as a crime-ridden relic of history. In 1975, the city government avoided bankruptcy only through a federal loan and debt restructuring by the Municipal Assistance Corporation, headed by Felix Rohatyn. The city was also forced to accept increased financial scrutiny by an agency of New York State. In 1977, the city was struck by the New York City blackout of 1977 and serial slayings by the Son of Sam.

 

The 1980s began a rebirth of Wall Street, and the city reclaimed its role at the center of the worldwide financial industry. Unemployment and crime remained high, the latter reaching peak levels in some categories around the close of the decade and the beginning of the 1990s. Neighborhood restoration projects funded by the city and state had very good effects for New York, especially Bedford-Stuyvesant, Harlem, and The Bronx. The city later resumed its social and economic recovery, bolstered by the influx of Asians, Latin Americans, and U.S. citizens, and by new crime-fighting techniques on the part of the New York Police Department. In 1989, New York City elected its first African American Mayor, David Dinkins. He came out of the Harlem Clubhouse.

 

In the late 1990s, the city benefited from the nationwide fall of violent crime rates, the resurgence of the finance industry, and the growth of the "Silicon Alley", during the dot com boom, one of the factors in a decade of booming real estate values. New York was also able to attract more business and convert abandoned industrialized neighborhoods into arts or attractive residential neighborhoods; examples include the Meatpacking District and Chelsea (in Manhattan) and Williamsburg (in Brooklyn).

 

New York's population reached an all-time high in the 2000 census; according to census estimates since 2000, the city has continued to grow, including rapid growth in the most urbanized borough, Manhattan. During this period, New York City was a site of the September 11 attacks of 2001; 2,606 people who were in the towers and in the surrounding area were killed by a terrorist attack on the World Trade Center, an event considered highly traumatic for the city but which did not stop the city's rapid regrowth. On November 3, 2014, One World Trade Center opened on the site of the attack. Hurricane Sandy brought a destructive storm surge to New York in the evening of October 29, 2012, flooding numerous streets, tunnels, and subway lines in Lower Manhattan. It flooded low-lying areas of Brooklyn, Queens, and Staten Island. Electrical power was lost in many parts of the city and its suburbs.

The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the longest suspension bridge in the world at the time of its opening, with a main span of 1,595.5 feet (486.3 m) and a deck 127 ft (38.7 m) above mean high water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915.

 

Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century, which eventually led to the construction of the current span, designed by John A. Roebling. The project's chief engineer, his son Washington Roebling, contributed further design work, assisted by the latter's wife, Emily Warren Roebling. Construction started in 1870, with the Tammany Hall-controlled New York Bridge Company overseeing construction, although numerous controversies and the novelty of the design prolonged the project over thirteen years. Since opening, the Brooklyn Bridge has undergone several reconfigurations, having carried horse-drawn vehicles and elevated railway lines until 1950. To alleviate increasing traffic flows, additional bridges and tunnels were built across the East River. Following gradual deterioration, the Brooklyn Bridge has been renovated several times, including in the 1950s, 1980s, and 2010s.

 

The Brooklyn Bridge is the southernmost of the four toll-free vehicular bridges connecting Manhattan Island and Long Island, with the Manhattan Bridge, the Williamsburg Bridge, and the Queensboro Bridge to the north. Only passenger vehicles and pedestrian and bicycle traffic are permitted. A major tourist attraction since its opening, the Brooklyn Bridge has become an icon of New York City. Over the years, the bridge has been used as the location of various stunts and performances, as well as several crimes and attacks. The Brooklyn Bridge has been designated a National Historic Landmark, a New York City landmark, and a National Historic Civil Engineering Landmark.

 

The Brooklyn Bridge, an early example of a steel-wire suspension bridge, uses a hybrid cable-stayed/suspension bridge design, with both vertical and diagonal suspender cables. Its stone towers are neo-Gothic, with characteristic pointed arches. The New York City Department of Transportation (NYCDOT), which maintains the bridge, says that its original paint scheme was "Brooklyn Bridge Tan" and "Silver", although a writer for The New York Post states that it was originally entirely "Rawlins Red".

 

To provide sufficient clearance for shipping in the East River, the Brooklyn Bridge incorporates long approach viaducts on either end to raise it from low ground on both shores. Including approaches, the Brooklyn Bridge is a total of 6,016 feet (1,834 m) long when measured between the curbs at Park Row in Manhattan and Sands Street in Brooklyn. A separate measurement of 5,989 feet (1,825 m) is sometimes given; this is the distance from the curb at Centre Street in Manhattan.

 

The main span between the two suspension towers is 1,595.5 feet (486.3 m) long and 85 feet (26 m) wide. The bridge "elongates and contracts between the extremes of temperature from 14 to 16 inches". Navigational clearance is 127 ft (38.7 m) above mean high water (MHW). A 1909 Engineering Magazine article said that, at the center of the span, the height above MHW could fluctuate by more than 9 feet (2.7 m) due to temperature and traffic loads, while more rigid spans had a lower maximum deflection.

 

The side spans, between each suspension tower and each side's suspension anchorages, are 930 feet (280 m) long. At the time of construction, engineers had not yet discovered the aerodynamics of bridge construction, and bridge designs were not tested in wind tunnels. It was coincidental that the open truss structure supporting the deck is, by its nature, subject to fewer aerodynamic problems. This is because John Roebling designed the Brooklyn Bridge's truss system to be six to eight times as strong as he thought it needed to be. However, due to a supplier's fraudulent substitution of inferior-quality cable in the initial construction, the bridge was reappraised at the time as being only four times as strong as necessary.

 

The main span and side spans are supported by a structure containing six trusses running parallel to the roadway, each of which is 33 feet (10 m) deep. The trusses allow the Brooklyn Bridge to hold a total load of 18,700 short tons (16,700 long tons), a design consideration from when it originally carried heavier elevated trains. These trusses are held up by suspender ropes, which hang downward from each of the four main cables. Crossbeams run between the trusses at the top, and diagonal and vertical stiffening beams run on the outside and inside of each roadway.

 

An elevated pedestrian-only promenade runs in between the two roadways and 18 feet (5.5 m) above them. It typically runs 4 feet (1.2 m) below the level of the crossbeams, except at the areas surrounding each tower. Here, the promenade rises to just above the level of the crossbeams, connecting to a balcony that slightly overhangs the two roadways. The path is generally 10 to 17 feet (3.0 to 5.2 m) wide. The iron railings were produced by Janes & Kirtland, a Bronx iron foundry that also made the United States Capitol dome and the Bow Bridge in Central Park.

 

Each of the side spans is reached by an approach ramp. The 971-foot (296 m) approach ramp from the Brooklyn side is shorter than the 1,567-foot (478 m) approach ramp from the Manhattan side. The approaches are supported by Renaissance-style arches made of masonry; the arch openings themselves were filled with brick walls, with small windows within. The approach ramp contains nine arch or iron-girder bridges across side streets in Manhattan and Brooklyn.

 

Underneath the Manhattan approach, a series of brick slopes or "banks" was developed into a skate park, the Brooklyn Banks, in the late 1980s. The park uses the approach's support pillars as obstacles. In the mid-2010s, the Brooklyn Banks were closed to the public because the area was being used as a storage site during the bridge's renovation. The skateboarding community has attempted to save the banks on multiple occasions; after the city destroyed the smaller banks in the 2000s, the city government agreed to keep the larger banks for skateboarding. When the NYCDOT removed the bricks from the banks in 2020, skateboarders started an online petition.

 

The Brooklyn Bridge contains four main cables, which descend from the tops of the suspension towers and help support the deck. Two are located to the outside of the bridge's roadways, while two are in the median of the roadways. Each main cable measures 15.75 inches (40.0 cm) in diameter and contains 5,282 parallel, galvanized steel wires wrapped closely together in a cylindrical shape. These wires are bundled in 19 individual strands, with 278 wires to a strand. This was the first use of bundling in a suspension bridge and took several months for workers to tie together. Since the 2000s, the main cables have also supported a series of 24-watt LED lighting fixtures, referred to as "necklace lights" due to their shape.

 

In addition, 1,520 galvanized steel wire suspender cables hang downward from the main cables, and another 400 cable stays extend diagonally from the towers. These wires hold up the truss structure around the bridge deck.

 

Each side of the bridge contains an anchorage for the main cables. The anchorages are trapezoidal limestone structures located slightly inland of the shore, measuring 129 by 119 feet (39 by 36 m) at the base and 117 by 104 feet (36 by 32 m) at the top. Each anchorage weighs 60,000 short tons (54,000 long tons; 54,000 t). The Manhattan anchorage rests on a foundation of bedrock while the Brooklyn anchorage rests on clay.

 

The anchorages both have four anchor plates, one for each of the main cables, which are located near ground level and parallel to the ground. The anchor plates measure 16 by 17.5 feet (4.9 by 5.3 m), with a thickness of 2.5 feet (0.76 m) and weigh 46,000 pounds (21,000 kg) each. Each anchor plate is connected to the respective main cable by two sets of nine eyebars, each of which is about 12.5 feet (3.8 m) long and up to 9 by 3 inches (229 by 76 mm) thick. The chains of eyebars curve downward from the cables toward the anchor plates, and the eyebars vary in size depending on their position.

 

The anchorages also contain numerous passageways and compartments. Starting in 1876, in order to fund the bridge's maintenance, the New York City government made the large vaults under the bridge's Manhattan anchorage available for rent, and they were in constant use during the early 20th century. The vaults were used to store wine, as they were kept at a consistent 60 °F (16 °C) temperature due to a lack of air circulation. The Manhattan vault was called the "Blue Grotto" because of a shrine to the Virgin Mary next to an opening at the entrance. The vaults were closed for public use in the late 1910s and 1920s during World War I and Prohibition but were reopened thereafter. When New York magazine visited one of the cellars in 1978, it discovered a "fading inscription" on a wall reading: "Who loveth not wine, women and song, he remaineth a fool his whole life long." Leaks found within the vault's spaces necessitated repairs during the late 1980s and early 1990s. By the late 1990s, the chambers were being used to store maintenance equipment.

 

The towers rest on underwater caissons made of southern yellow pine. Both caissons contain interior spaces that were used by construction workers. The Manhattan side's caisson is slightly larger, measuring 172 by 102 feet (52 by 31 m) and located 78.5 feet (23.9 m) below high water, while the Brooklyn side's caisson measures 168 by 102 feet (51 by 31 m) and is located 44.5 feet (13.6 m) below high water. The caissons were designed to hold at least the weight of the towers which would exert a pressure of 5 short tons per square foot (49 t/m2) when fully built, but the caissons were over-engineered for safety. During an accident on the Brooklyn side, when air pressure was lost and the partially-built towers dropped full-force down, the caisson sustained an estimated pressure of 23 short tons per square foot (220 t/m2) with only minor damage. Most of the timber used in the bridge's construction, including in the caissons, came from mills at Gascoigne Bluff on St. Simons Island, Georgia.

 

The Brooklyn side's caisson, which was built first, originally had a height of 9.5 feet (2.9 m) and a ceiling composed of five layers of timber, each layer 1 foot (0.30 m) tall. Ten more layers of timber were later added atop the ceiling, and the entire caisson was wrapped in tin and wood for further protection against flooding. The thickness of the caisson's sides was 8 feet (2.4 m) at both the bottom and the top. The caisson had six chambers: two each for dredging, supply shafts, and airlocks.

 

The caisson on the Manhattan side was slightly different because it had to be installed at a greater depth. To protect against the increased air pressure at that depth, the Manhattan caisson had 22 layers of timber on its roof, seven more than its Brooklyn counterpart had. The Manhattan caisson also had fifty 4-inch (10 cm)-diameter pipes for sand removal, a fireproof iron-boilerplate interior, and different airlocks and communication systems.

 

New York, often called New York City or simply NYC, is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each of which is coextensive with a respective county. It is a global city and a cultural, financial, high-tech, entertainment, and media center with a significant influence on commerce, health care, scientific output, life sciences, research, technology, education, politics, tourism, dining, art, fashion, and sports. Home to the headquarters of the United Nations, New York is an important center for international diplomacy, and is sometimes described as the world's most important city and the capital of the world.

 

With an estimated population in 2022 of 8,335,897 distributed over 300.46 square miles (778.2 km2), the city is the most densely populated major city in the United States. New York has more than double the population of Los Angeles, the nation's second-most populous city. New York is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the U.S. by both population and urban area. With more than 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York City is one of the world's most populous megacities. The city and its metropolitan area are the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. In 2021, the city was home to nearly 3.1 million residents born outside the U.S., the largest foreign-born population of any city in the world.

 

New York City traces its origins to Fort Amsterdam and a trading post founded on the southern tip of Manhattan Island by Dutch colonists in approximately 1624. The settlement was named New Amsterdam (Dutch: Nieuw Amsterdam) in 1626 and was chartered as a city in 1653. The city came under English control in 1664 and was renamed New York after King Charles II granted the lands to his brother, the Duke of York. The city was temporarily regained by the Dutch in July 1673 and was renamed New Orange; however, the city has been named New York since November 1674. New York City was the capital of the United States from 1785 until 1790. The modern city was formed by the 1898 consolidation of its five boroughs: Manhattan, Brooklyn, Queens, The Bronx, and Staten Island, and has been the largest U.S. city ever since.

 

Anchored by Wall Street in the Financial District of Lower Manhattan, New York City has been called both the world's premier financial and fintech center and the most economically powerful city in the world. As of 2022, the New York metropolitan area is the largest metropolitan economy in the world with a gross metropolitan product of over US$2.16 trillion. If the New York metropolitan area were its own country, it would have the tenth-largest economy in the world. The city is home to the world's two largest stock exchanges by market capitalization of their listed companies: the New York Stock Exchange and Nasdaq. New York City is an established safe haven for global investors. As of 2023, New York City is the most expensive city in the world for expatriates to live. New York City is home to the highest number of billionaires, individuals of ultra-high net worth (greater than US$30 million), and millionaires of any city in the world

 

The written history of New York City began with the first European explorer, the Italian Giovanni da Verrazzano in 1524. European settlement began with the Dutch in 1608 and New Amsterdam was founded in 1624.

 

The "Sons of Liberty" campaigned against British authority in New York City, and the Stamp Act Congress of representatives from throughout the Thirteen Colonies met in the city in 1765 to organize resistance to Crown policies. The city's strategic location and status as a major seaport made it the prime target for British seizure in 1776. General George Washington lost a series of battles from which he narrowly escaped (with the notable exception of the Battle of Harlem Heights, his first victory of the war), and the British Army occupied New York and made it their base on the continent until late 1783, attracting Loyalist refugees.

 

The city served as the national capital under the Articles of Confederation from 1785 to 1789, and briefly served as the new nation's capital in 1789–90 under the United States Constitution. Under the new government, the city hosted the inauguration of George Washington as the first President of the United States, the drafting of the United States Bill of Rights, and the first Supreme Court of the United States. The opening of the Erie Canal gave excellent steamboat connections with upstate New York and the Great Lakes, along with coastal traffic to lower New England, making the city the preeminent port on the Atlantic Ocean. The arrival of rail connections to the north and west in the 1840s and 1850s strengthened its central role.

 

Beginning in the mid-19th century, waves of new immigrants arrived from Europe dramatically changing the composition of the city and serving as workers in the expanding industries. Modern New York traces its development to the consolidation of the five boroughs in 1898 and an economic and building boom following the Great Depression and World War II. Throughout its history, New York has served as a main port of entry for many immigrants, and its cultural and economic influence has made it one of the most important urban areas in the United States and the world. The economy in the 1700s was based on farming, local production, fur trading, and Atlantic jobs like shipbuilding. In the 1700s, New York was sometimes referred to as a breadbasket colony, because one of its major crops was wheat. New York colony also exported other goods included iron ore as a raw material and as manufactured goods such as tools, plows, nails and kitchen items such as kettles, pans and pots.

 

The area that eventually encompassed modern day New York was inhabited by the Lenape people. These groups of culturally and linguistically related Native Americans traditionally spoke an Algonquian language now referred to as Unami. Early European settlers called bands of Lenape by the Unami place name for where they lived, such as "Raritan" in Staten Island and New Jersey, "Canarsee" in Brooklyn, and "Hackensack" in New Jersey across the Hudson River from Lower Manhattan. Some modern place names such as Raritan Bay and Canarsie are derived from Lenape names. Eastern Long Island neighbors were culturally and linguistically more closely related to the Mohegan-Pequot peoples of New England who spoke the Mohegan-Montauk-Narragansett language.

 

These peoples made use of the abundant waterways in the New York region for fishing, hunting trips, trade, and occasionally war. Many paths created by the indigenous peoples are now main thoroughfares, such as Broadway in Manhattan, the Bronx, and Westchester. The Lenape developed sophisticated techniques of hunting and managing their resources. By the time of the arrival of Europeans, they were cultivating fields of vegetation through the slash and burn technique, which extended the productive life of planted fields. They also harvested vast quantities of fish and shellfish from the bay. Historians estimate that at the time of European settlement, approximately 5,000 Lenape lived in 80 settlements around the region.

 

The first European visitor to the area was Giovanni da Verrazzano, an Italian in command of the French ship La Dauphine in 1524. It is believed he sailed into Upper New York Bay, where he encountered native Lenape, returned through the Narrows, where he anchored the night of April 17, and left to continue his voyage. He named the area New Angoulême (La Nouvelle-Angoulême) in honor of Francis I, King of France of the royal house of Valois-Angoulême and who had been Count of Angoulême from 1496 until his coronation in 1515. The name refers to the town of Angoulême, in the Charente département of France. For the next century, the area was occasionally visited by fur traders or explorers, such as by Esteban Gomez in 1525.

 

European exploration continued on September 2, 1609, when the Englishman Henry Hudson, in the employ of the Dutch East India Company, sailed the Half Moon through the Narrows into Upper New York Bay. Like Christopher Columbus, Hudson was looking for a westerly passage to Asia. He never found one, but he did take note of the abundant beaver population. Beaver pelts were in fashion in Europe, fueling a lucrative business. Hudson's report on the regional beaver population served as the impetus for the founding of Dutch trading colonies in the New World. The beaver's importance in New York's history is reflected by its use on the city's official seal.

 

The first Dutch fur trading posts and settlements were in 1614 near present-day Albany, New York, the same year that New Netherland first appeared on maps. Only in May 1624 did the Dutch West India Company land a number of families at Noten Eylant (today's Governors Island) off the southern tip of Manhattan at the mouth of the North River (today's Hudson River). Soon thereafter, most likely in 1626, construction of Fort Amsterdam began. Later, the Dutch West Indies Company imported African slaves to serve as laborers; they were forced to build the wall that defended the town against English and Indian attacks. Early directors included Willem Verhulst and Peter Minuit. Willem Kieft became director in 1638 but five years later was embroiled in Kieft's War against the Native Americans. The Pavonia Massacre, across the Hudson River in present-day Jersey City, resulted in the death of 80 natives in February 1643. Following the massacre, Algonquian tribes joined forces and nearly defeated the Dutch. Holland sent additional forces to the aid of Kieft, leading to the overwhelming defeat of the Native Americans and a peace treaty on August 29, 1645.

 

On May 27, 1647, Peter Stuyvesant was inaugurated as director general upon his arrival and ruled as a member of the Dutch Reformed Church. The colony was granted self-government in 1652, and New Amsterdam was incorporated as a city on February 2, 1653. The first mayors (burgemeesters) of New Amsterdam, Arent van Hattem and Martin Cregier, were appointed in that year. By the early 1660s, the population consisted of approximately 1500 Europeans, only about half of whom were Dutch, and 375 Africans, 300 of whom were slaves.

 

A few of the original Dutch place names have been retained, most notably Flushing (after the Dutch town of Vlissingen), Harlem (after Haarlem), and Brooklyn (after Breukelen). Few buildings, however, remain from the 17th century. The oldest recorded house still in existence in New York, the Pieter Claesen Wyckoff House in Brooklyn, dates from 1652.

 

On August 27, 1664, four English frigates under the command of Col. Richard Nicolls sailed into New Amsterdam's harbor and demanded New Netherland's surrender, as part of an effort by King Charles II's brother James, Duke of York, the Lord High Admiral to provoke the Second Anglo-Dutch War. Two weeks later, Stuyvesant officially capitulated by signing Articles of Surrender and in June 1665, the town was reincorporated under English law and renamed "New York" after the Duke, and Fort Orange was renamed "Fort Albany". The war ended in a Dutch victory in 1667, but the colony remained under English rule as stipulated in the Treaty of Breda. During the Third Anglo-Dutch War, the Dutch briefly recaptured the city in 1673, renaming the city "New Orange", before permanently ceding the colony of New Netherland to England for what is now Suriname in November 1674 at the Treaty of Westminster.

 

The colony benefited from increased immigration from Europe and its population grew faster. The Bolting Act of 1678, whereby no mill outside the city was permitted to grind wheat or corn, boosted growth until its repeal in 1694, increasing the number of houses over the period from 384 to 983.

 

In the context of the Glorious Revolution in England, Jacob Leisler led Leisler's Rebellion and effectively controlled the city and surrounding areas from 1689 to 1691, before being arrested and executed.

 

Lawyers

In New York at first, legal practitioners were full-time businessmen and merchants, with no legal training, who had watched a few court proceedings, and mostly used their own common sense together with snippets they had picked up about English law. Court proceedings were quite informal, for the judges had no more training than the attorneys.

 

By the 1760s, the situation had dramatically changed. Lawyers were essential to the rapidly growing international trade, dealing with questions of partnerships, contracts, and insurance. The sums of money involved were large, and hiring an incompetent lawyer was a very expensive proposition. Lawyers were now professionally trained, and conversant in an extremely complex language that combined highly specific legal terms and motions with a dose of Latin. Court proceedings became a baffling mystery to the ordinary layman. Lawyers became more specialized and built their reputation, and their fee schedule, on the basis of their reputation for success. But as their status, wealth and power rose, animosity grew even faster. By the 1750s and 1760s, there was a widespread attack ridiculing and demeaning the lawyers as pettifoggers (lawyers lacking sound legal skills). Their image and influence declined. The lawyers organized a bar association, but it fell apart in 1768 during the bitter political dispute between the factions based in the Delancey and Livingston families. A large fraction of the prominent lawyers were Loyalists; their clientele was often to royal authority or British merchants and financiers. They were not allowed to practice law unless they took a loyalty oath to the new United States of America. Many went to Britain or Canada (primarily to New Brunswick and Nova Scotia) after losing the war.

 

For the next century, various attempts were made, and failed, to build an effective organization of lawyers. Finally a Bar Association emerged in 1869 that proved successful and continues to operate.

 

By 1700, the Lenape population of New York had diminished to 200. The Dutch West Indies Company transported African slaves to the post as trading laborers used to build the fort and stockade, and some gained freedom under the Dutch. After the seizure of the colony in 1664, the slave trade continued to be legal. In 1703, 42% of the New York households had slaves; they served as domestic servants and laborers but also became involved in skilled trades, shipping and other fields. Yet following reform in ethics according to American Enlightenment thought, by the 1770s slaves made up less than 25% of the population.

 

By the 1740s, 20% of the residents of New York were slaves, totaling about 2,500 people.

 

After a series of fires in 1741, the city panicked over rumors of its black population conspiring with some poor whites to burn the city. Historians believe their alarm was mostly fabrication and fear, but officials rounded up 31 black and 4 white people, who over a period of months were convicted of arson. Of these, the city executed 13 black people by burning them alive and hanged the remainder of those incriminated.

 

The Stamp Act and other British measures fomented dissent, particularly among Sons of Liberty who maintained a long-running skirmish with locally stationed British troops over Liberty Poles from 1766 to 1776. The Stamp Act Congress met in New York City in 1765 in the first organized resistance to British authority across the colonies. After the major defeat of the Continental Army in the Battle of Long Island in late 1776, General George Washington withdrew to Manhattan Island, but with the subsequent defeat at the Battle of Fort Washington the island was effectively left to the British. The city became a haven for loyalist refugees, becoming a British stronghold for the entire war. Consequently, the area also became the focal point for Washington's espionage and intelligence-gathering throughout the war.

 

New York was greatly damaged twice by fires of suspicious origin, with the Loyalists and Patriots accusing each other of starting the conflagration. The city became the political and military center of operations for the British in North America for the remainder of the war. Continental Army officer Nathan Hale was hanged in Manhattan for espionage. In addition, the British began to hold the majority of captured American prisoners of war aboard prison ships in Wallabout Bay, across the East River in Brooklyn. More Americans lost their lives aboard these ships than died in all the battles of the war. The British occupation lasted until November 25, 1783. George Washington triumphantly returned to the city that day, as the last British forces left the city.

 

Starting in 1785 the Congress met in the city of New York under the Articles of Confederation. In 1789, New York became the first national capital under the new Constitution. The Constitution also created the current Congress of the United States, and its first sitting was at Federal Hall on Wall Street. The first Supreme Court sat there. The United States Bill of Rights was drafted and ratified there. George Washington was inaugurated at Federal Hall. New York remained the national capital until 1790, when the role was transferred to Philadelphia.

 

During the 19th century, the city was transformed by immigration, a visionary development proposal called the Commissioners' Plan of 1811 which expanded the city street grid to encompass all of Manhattan, and the opening of the Erie Canal in 1825, which connected the Atlantic port to the vast agricultural markets of the Midwestern United States and Canada. By 1835, New York had surpassed Philadelphia as the largest city in the United States. New York grew as an economic center, first as a result of Alexander Hamilton's policies and practices as the first Secretary of the Treasury.

 

In 1842, water was piped from a reservoir to supply the city for the first time.

 

The Great Irish Famine (1845–1850) brought a large influx of Irish immigrants, and by 1850 the Irish comprised one quarter of the city's population. Government institutions, including the New York City Police Department and the public schools, were established in the 1840s and 1850s to respond to growing demands of residents. In 1831, New York University was founded by U.S. Secretary of the Treasury Albert Gallatin as a non-denominal institution surrounding Washington Square Park.

 

This period started with the 1855 inauguration of Fernando Wood as the first mayor from Tammany Hall. It was the political machine based among Irish Americans that controlled the local Democratic Party. It usually dominated local politics throughout this period and into the 1930s. Public-minded members of the merchant community pressed for a Central Park, which was opened to a design competition in 1857; it became the first landscape park in an American city.

 

During the American Civil War (1861–1865), the city was affected by its history of strong commercial ties to the South; before the war, half of its exports were related to cotton, including textiles from upstate mills. Together with its growing immigrant population, which was angry about conscription, sympathies among residents were divided for both the Union and Confederacy at the outbreak of war. Tensions related to the war culminated in the Draft Riots of 1863 led by Irish Catholics, who attacked black neighborhood and abolitionist homes. Many blacks left the city and moved to Brooklyn. After the Civil War, the rate of immigration from Europe grew steeply, and New York became the first stop for millions seeking a new and better life in the United States, a role acknowledged by the dedication of the Statue of Liberty in 1886.

 

From 1890 to 1930, the largest cities, led by New York, were the focus of international attention. The skyscrapers and tourist attractions were widely publicized. Suburbs were emerging as bedroom communities for commuters to the central city. San Francisco dominated the West, Atlanta dominated the South, Boston dominated New England; Chicago dominated the Midwest United States. New York City dominated the entire nation in terms of communications, trade, finance, popular culture, and high culture. More than a fourth of the 300 largest corporations in 1920 were headquartered here.

 

In 1898, the modern City of New York was formed with the consolidation of Brooklyn (until then an independent city), Manhattan, and outlying areas. Manhattan and the Bronx were established as two separate boroughs and joined with three other boroughs created from parts of adjacent counties to form the new municipal government originally called "Greater New York". The Borough of Brooklyn incorporated the independent City of Brooklyn, recently joined to Manhattan by the Brooklyn Bridge; the Borough of Queens was created from western Queens County (with the remnant established as Nassau County in 1899); and the Borough of Richmond contained all of Richmond County. Municipal governments contained within the boroughs were abolished, and the county governmental functions were absorbed by the city or each borough. In 1914, the New York State Legislature created Bronx County, making five counties coterminous with the five boroughs.

 

The Bronx had a steady boom period during 1898–1929, with a population growth by a factor of six from 200,000 in 1900 to 1.3 million in 1930. The Great Depression created a surge of unemployment, especially among the working class, and a slow-down of growth.

 

On June 15, 1904, over 1,000 people, mostly German immigrant women and children, were killed when the excursion steamship General Slocum caught fire and sank. It is the city's worst maritime disaster. On March 25, 1911, the Triangle Shirtwaist Factory fire in Greenwich Village took the lives of 146 garment workers. In response, the city made great advancements in the fire department, building codes, and workplace regulations.

 

Throughout the first half of the 20th century, the city became a world center for industry, commerce, and communication, marking its rising influence with such events as the Hudson-Fulton Celebration of 1909. Interborough Rapid Transit (the first New York City Subway company) began operating in 1904, and the railroads operating out of Grand Central Terminal and Pennsylvania Station thrived.

 

From 1918 to 1920, New York City was affected by the largest rent strike wave in its history. Somewhere between several 10,000's and 100,000's of tenants struck across the city. A WW1 housing and coal shortage sparked the strikes. It became marked both by occasional violent scuffles and the Red Scare.  It would lead to the passage of the first rent laws in the nations history.

 

The city was a destination for internal migrants as well as immigrants. Through 1940, New York was a major destination for African Americans during the Great Migration from the rural American South. The Harlem Renaissance flourished during the 1920s and the era of Prohibition. New York's ever accelerating changes and rising crime and poverty rates were reduced after World War I disrupted trade routes, the Immigration Restriction Acts limited additional immigration after the war, and the Great Depression reduced the need for new labor. The combination ended the rule of the Gilded Age barons. As the city's demographics temporarily stabilized, labor unionization helped the working class gain new protections and middle-class affluence, the city's government and infrastructure underwent a dramatic overhaul under Fiorello La Guardia, and his controversial parks commissioner, Robert Moses, ended the blight of many tenement areas, expanded new parks, remade streets, and restricted and reorganized zoning controls.

 

For a while, New York ranked as the most populous city in the world, overtaking London in 1925, which had reigned for a century.[58] During the difficult years of the Great Depression, the reformer Fiorello La Guardia was elected as mayor, and Tammany Hall fell after eighty years of political dominance.

 

Despite the effects of the Great Depression, some of the world's tallest skyscrapers were built during the 1930s. Art Deco architecture—such as the iconic Chrysler Building, Empire State Building, and 30 Rockefeller Plaza— came to define the city's skyline. The construction of the Rockefeller Center occurred in the 1930s and was the largest-ever private development project at the time. Both before and especially after World War II, vast areas of the city were also reshaped by the construction of bridges, parks and parkways coordinated by Robert Moses, the greatest proponent of automobile-centered modernist urbanism in America.

 

Returning World War II veterans and immigrants from Europe created a postwar economic boom. Demands for new housing were aided by the G.I. Bill for veterans, stimulating the development of huge suburban tracts in eastern Queens and Nassau County. The city was extensively photographed during the post–war years by photographer Todd Webb.

 

New York emerged from the war as the leading city of the world, with Wall Street leading the United States ascendancy. In 1951, the United Nations relocated from its first headquarters in Flushing Meadows Park, Queens, to the East Side of Manhattan. During the late 1960s, the views of real estate developer and city leader Robert Moses began to fall out of favor as the anti-urban renewal views of Jane Jacobs gained popularity. Citizen rebellion stopped a plan to construct an expressway through Lower Manhattan.

 

After a short war boom, the Bronx declined from 1950 to 1985, going from predominantly moderate-income to mostly lower-income, with high rates of violent crime and poverty. The Bronx has experienced an economic and developmental resurgence starting in the late 1980s that continues into today.

 

The transition away from the industrial base toward a service economy picked up speed, while the jobs in the large shipbuilding and garment industries declined sharply. The ports converted to container ships, costing many traditional jobs among longshoremen. Many large corporations moved their headquarters to the suburbs or to distant cities. At the same time, there was enormous growth in services, especially finance, education, medicine, tourism, communications and law. New York remained the largest city and largest metropolitan area in the United States, and continued as its largest financial, commercial, information, and cultural center.

 

Like many major U.S. cities, New York suffered race riots, gang wars and some population decline in the late 1960s. Street activists and minority groups such as the Black Panthers and Young Lords organized rent strikes and garbage offensives, demanding improved city services for poor areas. They also set up free health clinics and other programs, as a guide for organizing and gaining "Power to the People." By the 1970s the city had gained a reputation as a crime-ridden relic of history. In 1975, the city government avoided bankruptcy only through a federal loan and debt restructuring by the Municipal Assistance Corporation, headed by Felix Rohatyn. The city was also forced to accept increased financial scrutiny by an agency of New York State. In 1977, the city was struck by the New York City blackout of 1977 and serial slayings by the Son of Sam.

 

The 1980s began a rebirth of Wall Street, and the city reclaimed its role at the center of the worldwide financial industry. Unemployment and crime remained high, the latter reaching peak levels in some categories around the close of the decade and the beginning of the 1990s. Neighborhood restoration projects funded by the city and state had very good effects for New York, especially Bedford-Stuyvesant, Harlem, and The Bronx. The city later resumed its social and economic recovery, bolstered by the influx of Asians, Latin Americans, and U.S. citizens, and by new crime-fighting techniques on the part of the New York Police Department. In 1989, New York City elected its first African American Mayor, David Dinkins. He came out of the Harlem Clubhouse.

 

In the late 1990s, the city benefited from the nationwide fall of violent crime rates, the resurgence of the finance industry, and the growth of the "Silicon Alley", during the dot com boom, one of the factors in a decade of booming real estate values. New York was also able to attract more business and convert abandoned industrialized neighborhoods into arts or attractive residential neighborhoods; examples include the Meatpacking District and Chelsea (in Manhattan) and Williamsburg (in Brooklyn).

 

New York's population reached an all-time high in the 2000 census; according to census estimates since 2000, the city has continued to grow, including rapid growth in the most urbanized borough, Manhattan. During this period, New York City was a site of the September 11 attacks of 2001; 2,606 people who were in the towers and in the surrounding area were killed by a terrorist attack on the World Trade Center, an event considered highly traumatic for the city but which did not stop the city's rapid regrowth. On November 3, 2014, One World Trade Center opened on the site of the attack. Hurricane Sandy brought a destructive storm surge to New York in the evening of October 29, 2012, flooding numerous streets, tunnels, and subway lines in Lower Manhattan. It flooded low-lying areas of Brooklyn, Queens, and Staten Island. Electrical power was lost in many parts of the city and its suburbs.

...because crosswalks don't happen by themselves. Lower East Side, Manhattan

 

[A7ii - 4203 Lr2015]

The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan at Canal Street with Downtown Brooklyn at the Flatbush Avenue Extension. The main span is 1,470 ft (448 m) long, with the suspension cables being 3,224 ft (983 m) long. The bridge's total length is 6,855 ft (2,089 m). It is one of four toll-free bridges spanning the East River; the other three are the Queensboro, Williamsburg, and Brooklyn Bridges.

 

The bridge opened to traffic on December 31, 1909. It was built by The Phoenix Bridge Company and designed by Leon Moisseiff, and is noted for its innovative design. As the first suspension bridge to employ Josef Melan's deflection theory for the stiffening of its deck, it is considered to be the forerunner of modern suspension bridges, and this design served as the model for many of the long-span suspension bridges built in the first half of the twentieth century. The Manhattan Bridge was also the first suspension bridge to utilize a Warren truss in its design.

 

History

 

The Manhattan Bridge was the last of the three suspension bridges built across the lower East River, following the Brooklyn and Williamsburg Bridges. In the earliest plans, the Manhattan Bridge was to have been called "Bridge No. 3" because it was the third bridge to be built. The Manhattan Bridge's current name was given in 1902. The name was confirmed in 1904. The New York Times criticized the name as "meaningless" and that the Manhattan Bridge's name "would have geographical and historical significance if it were known as the Wallabout Bridge". This was a reference to Wallabout Bay, located near the proposed bridge's Brooklyn side. In 1905, the Times raised another objection, stating, "All bridges across the East River are Manhattan bridges. When there was only one, it was well enough to call it the Brooklyn Bridge, or the East River Bridge".

Construction

 

Construction on the bridge's towers had commenced by at least 1901. By 1903, three workers had died while working on the Brooklyn-side tower's caisson. A $10 million grant for the bridge's construction was granted in May 1904 with the expectation that work on the span would start later that year.

 

A plan for the suspension-bridge span was announced in 1903. Elevated and trolley routes would use the Manhattan Bridge, and there would be large balconies and enormous spaces within the towers' anchorages. However, the Municipal Art Commission raised objections to one of the bridge's plans, which delayed the start of construction for the span. Another set of plans was unveiled in June 1904 by New York City Bridge Commissioner Gustav Lindenthal, but the second plan was also rejected. The dispute revolved around whether eyebars or wire cables should be used in the new bridge. The MAC voted to use wire cables in the bridge in September 1904. Because of this dispute, the plans for Manhattan Bridge are sometimes mistakenly attributed to Lindenthal. Other delays arose over the proposed placement of the bridge's termini on either side.

The Manhattan Bridge under construction in March 1909

 

The first temporary wire between the Manhattan Bridge's two towers was strung in June 1908. It was to be replaced later with permanent, thicker main cables, each 21 inches (53 cm) thick, on both sides of the bridge's deck. By this time, the construction cost had increased to $22 million. During the stringing of the anchorages, one of the cables on the Brooklyn side broke loose, injuring two people. The last of the suspender ropes supporting the main cables was strung in December of that year. The cables had been strung in four months, The construction of the bridge span required 30,000 tons of steel. Erection of the superstructure and steel fabrication were contracted to The Phoenix Bridge Company. The first girder for the new bridge was installed in February 1909. By April, the majority of the span had been fitted into place between the main cables.

 

The New York City Rapid Transit Commission recommended the construction of a subway line across the Manhattan Bridge in 1905. This line was approved in 1907. The New York City Public Service Commission requested permission to start constructing the subway tracks in March 1908. This plan was approved in May.

  

A group of 100 "leading citizens of Brooklyn" walked over the bridge on December 5, 1909, marking the unofficial completion of the bridge. The bridge was officially opened by outgoing Mayor George B. McClellan Jr. on December 31, 1909. Shortly after opening, a fire on the Brooklyn side of the Manhattan Bridge damaged the structure.

 

Later history

Floodlights and barbed-wire fences were installed at the bases of the bridge's anchorages in 1951, during the Cold War. The installations were fortified to protect against "possible sabotage attempts under wartime conditions". The anchorages themselves were sealed.

 

The subway trains crossing the Manhattan Bridge had a major impact on its condition (see § Trackage history), and the bridge started to tilt to one side based on how many trains used that side. This had supposedly been a problem since the tracks opened in 1917. In 1956, the bridge was renovated in order to rectify this tilt. However, by 1978, the Manhattan Bridge had deteriorated to such a point that the United States Congress voted to allocate money to repair the bridge, as well as several others in New York City. Minor repair work started in 1982. A discretionary grant for $50 million was allocated to these bridges' repairs in 1985. The first phase of repairs started that year. The bridge's condition was blamed on the imbalance in the number of trains crossing the bridge, as well as deferred maintenance during the New York City fiscal crisis of the 1970s.

 

In April 1986, workers temporarily closed the Manhattan-bound roadway on the upper level in order to repair the deck there. The north-side subway tracks, underneath the Manhattan-bound roadway, were also closed during this time. In December 1987, inspectors also shut one lane of the lower level due to a crack in the deck. The New York City Department of Transportation published a list of 17 structurally deficient bridges in the city. Among them was the Manhattan Bridge, which needed $166 million in repairs to fix "cable anchors and torsion of steel members as subways cross". Repairs on the northern side of the Manhattan Bridge were complete by the end of 1988, and the subway tracks on the north side were reopened. Simultaneous with the reopening of the north side, the south-side tracks were closed.[48] In 1991, trucks were banned from the lower level because they were too heavy for the decaying bridge.

 

"Major" repair work on the southern side began in 1992. The Yonkers Construction Company was awarded a $97.8 million contract for the repair project in August 1992. City Comptroller Elizabeth Holtzman originally denied the contract to the company because of concerns about corruption, but she was overridden by Mayor David Dinkins, who wanted to complete repairs quickly. At the same time, the NYCDOT increased the frequency of maintenance inspections for the bridge, after inspectors found holes in beams that had been deemed structurally sound during previous inspections. The Brooklyn-bound roadway on the upper level was closed from 1993 to 1996 so that side of the bridge could be repaired. The bridge repairs were repeatedly delayed as the renovation process uncovered more serious structural problems underlying the bridge. The original plans had been to complete the renovations by 1995 for $150 million, but by 1996, the renovation was slated to be complete in 2003 at a cost of $452 million. By 2001, it was estimated that the total cost of the renovations had reached half a billion dollars, including $260 million for the south side and another $175 million for the north side. At the time, the NYCDOT had set a January 2004 deadline for the renovation.

 

The original pedestrian walkway on the south side of the bridge was reopened after forty years in June 2001. It was shared with bicycles until late summer 2004, when a dedicated bicycle path was opened on the north side of the bridge. The northern bridge bike path is notable for poor signage that leads to cyclist and pedestrian conflicts. By the time work on the bridge was completed in 2004, the final cost of the renovation totaled $800 million.

 

To celebrate the bridge's centennial anniversary, a series of events and exhibits were organized by the New York City Bridge Centennial Commission in October 2009. These included a ceremonial parade across the Manhattan Bridge on the morning of October 4 and a fireworks display in the evening.[57] In 2009, the bridge was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.
