Coalbrookdale-Ironbridge, England
Completed in 1779
This bridge is recognized as the first iron bridge in the world. This rural region of England was an important industrial area thanks to coal deposits near the surface. In 1776 the nearest bridge that enabled people and goods to pass over the River Severn was two miles away at Buildwas. There was a ferry crossing, but the trip was difficult and dangerous especially in winter. In 1776, an Act to build a bridge to remedy this situation received Royal Assent.
The bridge was cast in the local foundries and built across the River Severn by a man named Abraham Darby III. Abraham Darby was the first, in 1709, to master the science of smelting iron with coke, rather than costly charcoal. He leased an old furnace in Coalbrookdale to do so. The son of a Quaker farmer, Darby was the first to use the cheaper iron, rather than brass, to cast strong thin pots for the poor. Under his son and grandson, the Coalbrookdale works flourished. It was in November 1777 that Abraham Darby III began erecting the 378 tons of cast iron to build the bridge which spans the 30 m/100 ft of the Shropshire gorge. Designed by Thomas Farnolls Pritchard, the bridge itself was completed in 1779 with the fitting of the balustrade and the road surface along with the obligatory toll house.
The town of Ironbridge began to grow around the Bridge immediately after it opened to traffic. After it survived the great floods of 1795, cast iron was used widely in construction of bridges, buildings and aqueducts. Standing today, the Iron Bridge is an outstanding international monument to both the civil engineering profession and the industrial revolution.

In a special summer UrbanPlan Scholars program, four teams presented their proposals for a six-acre parcel next to UH West Oahu. They had to address zoning requirements, affordable housing/workforce housing, rail/transit issues, agriculture, and energy.
UrbanPlan is a global competition run by the international Urban Land Institute. Hawaii schools have taken top honors in the global competition two years in a row, including Iolani School last month, and Iolani and Kalani two years ago.
Teams were made up of local high school students from Iolani, Kalani, LeJardin, MidPac, Punahou, and St. Andrews.
They conducted outreach to stakeholders and residents in West Oahu and found affordable housing to be the number one community need.
Ideas ranged from rooftop greenhouses and beekeeping to fully solar-powered facilities to integrating UHWO student and campus life.
Judges included Bob Harrison (FHB), Duff Janus (ASB), Brennon Morioka (UH), Mike Gabbard (Senate), Jim Houchens (Mitre), and Alana Kobayashi.
Bernice Glenn Bowers helped them plan for future high-tech industry in the area, doubled the size of the cash prize to $1,500.

Sydney, New South Wales, Australia
Completed 1932
The design of the Sydney Harbour Bridge closely resembles the Hell Gate Bridge over the East River in New York City, conceived in 1916 by noted engineer Gustav Lindenthal and his chief assistant, O.H. Ammann.
The Sydney Harbour Bridge, with a span of 1,650 feet, is not only the longest single-arch bridge ever built outside of the United States; its 160-foot width - enough to carry eight lanes of automobile traffic, two sets of train tracks, a bicycle path, and a pedestrian walkway - also qualifies it as the widest long-span bridge anywhere in the world. Seated at the mouth of one of the world's most beautiful harbors, the bridge is a massive engineering achievement and a dramatic statement of Australia's standing among the leading nations of the 20th century.
The bridge and its approach spans, totaling 2 3/4 miles in length, required 52,000 tons of steel and more than 6,000,000 rivets to construct, in a job that lasted nine years. A pair of 285-foot granite-faced pylons at each end of the main span help anchor the bridge and add to its aesthetic appeal. Guided tours from a visitor's center and museum housed in one of the bridge's pylons allow intrepid climbers to cross the very top of the bridge's twin arches.

Pelham Ridge Elementary School was designed by Goodwyn Mills Cawood. Pelham Ridge Elementary is the first new construction school designed for the newly-formed Pelham City School Board. The new elementary school is a two-story brick and stone building with wood elements, which reflects the desired character and materiality of the existing schools in the district. Pelham Ridge incorporates a variety of learning environments in addition to the typical classroom. These supplemental learning spaces include two “break-out” learning spaces, a flexible classroom, and two courtyards. Two of the classroom wings adjacent to the courtyards are designed to function as storm shelters and meet the Alabama Building Commission’s state standard for storm shelters, ICC 500.

Goes from Gebel el Qatani and ends at Qasr El - Sagha, Eygpt
Built sometime between 26th and 22nd Centuries B.C.
The Lake Moeris Quarry Road, in the Faiyum District of Eygpt, is the oldest road in the world of which a considerable part of its original pavement is still preserved. This road was used to help transport the heavy blocks of basalt from the quarry 43 miles southwest of Cairo to the royal sarcophagi and pavements for the mortuary temples at Giza just outside Cairo. The road covered the 7.5 miles from the quarry to Lake Moeris which, at that time, was 66 ft above sea level. When the Nile flooded and its waters reached a gap in the hills separating the Lake from the Nile, the Egyptians were able to float the blocks down to Cairo.
The road averaged a width of six and a half feet and was created with slabs of sandstone and limestone. The builders even included some logs of petrified wood. Since the pavement stones bore no deep grooves or other marks, geologists have speculated that logs were laid over the stones as a sled was drawn toward the lake. The stones prevented the sled from sinking into the desert sand.

Salt Lake City, Utah
Completed 1867
Just 20 years after settling the uninhabited Salt Lake valley, Brigham Young and his Mormon followers completed one of the nation's most impressive public structures. The 9,000-seat Mormon Tabernacle boasts a clear span roof measuring 150 feet by 250 feet, its timber trusses joined with wooden pegs and lashed with green rawhide, which shrank and tightened as it dried.
The building has remained structurally sound for more than 125 years and has seen few changes to its original design. It receives up to 3 million visitors a year and is home to the world famous Mormon Tabernacle Choir.
Facts
- Prominent railroad bridge engineer Henry Grow designed the roof using a system of lattice arches in place of internal supports.
- Stone and lumber were available in the surrounding mountains, but metal building components could not be shipped from the east until the transcontinental railroad reached Salt Lake City in 1869, two years after completion.
- The Mormon Tabernacle was the first building in the U.S. to be designated as a National Historic Civil Engineering Landmark by the ASCE.
