The Whipple Bowstring Truss Bridge was built from a design patented in 1841 by Squire Whipple. Whipple was the first person to understand the stresses in truss members and he developed the first theoretical formula to calculate stresses in the articulated truss. His bowstring truss was the first to use cast iron for compression and wrought iron for tension membranes.
The structure originally crossed the Cayadutta Creek in Johnstown, New York. It is one of five truss bridges built by Whipple in eastern New York and it is possibly the oldest. The City of Johnstown donated the bridge to Whipple's alma mater, Union College, in 1979.
Though the design and details of the bridge were patented, Whipple never was able to collect royalties. The State of New York adopted "Whipple's Patent Iron Arch Truss Bridge" as the standard for its canals but evaded royalty payments by declaring that the erection of the bridges was for the public good.

Folsom, California
Completed 1895
"The State [of California] agreed to construct the dam using convict labor for which consideration the State received a grant of land for the construction of a prison and water power rights from the impounded water. The work progressed slowly during the dry season by disinterested convict labor using hand tools since the use of machinery was forbidden."
- Historic Landmark Nomination Form, 1974
In 1895, Folsom Powerhouse transmitted 11,000 volts of electricity over a 22-mile stretch to power the streetcars of the Sacramento Electric Gas and Railway Company. Folsom also provided the long-distance, high voltage, three-phase transmission service for municipal and industrial power needs.
The success of this early system proved that low-cost hydroelectric energy could be provided to distant population centers. It served as an early prototype for modern hydraulic power generation and transmission facilities.
Although the lower powerhouse was taken off-line in 1920, the main powerhouse continued in operation until 1952. At that time, the dam was removed to make way for the new Folsom Dam. The original powerhouse is now part of the California State Park System.
Facts
- Water was supplied from a canal leading from a masonry dam, 650-feet long and 87-feet high, on the American River.
The dam contained 78,500 cubic yards of granite block masonry, united by mortar made from 20,000 barrels of cement.
- At the powerhouse, water passed through four 1,100 horsepower turbines.
- The turbines were connected to four 759-kilowatt generators, reported to be the largest in the world at that time.
- Spent water was discharged into a tailrace for return to the American River. A tailrace is the outflow duct or channel from a water wheel or water turbine.
- A small powerhouse was constructed on the tailrace channel to generate an additional 750 kilowatts. Its 26-strand rope drive transmitted energy from the turbine to the generator, which was located on higher ground.

The City of Hoover has seen enormous growth in its sports programs over the past 10 years and needed a new complex that would fulfill their existing needs, allow for growth and give the City the ability to create new revenue streams and take advantage of sports tourism by hosting large tournament events. Hoover had not built any new athletic facilities in 15 years. At the same time the City’s sports participation had increased by multiples of 200% - 500% depending on the sport. The growth was caused by increases in both youth and adult sports leagues, as well as the relatively recent popularity of additional sports.
The multi-purpose Finley Center, which connects to the existing Hoover Met baseball stadium with a covered walkway, is able to accommodate a full-size football or soccer field, nine regulation-size basketball courts, 12 regulation-size volleyball courts or six indoor tennis courts. It can also seat 2,400 for banquets and 5,000 for events with general seating, such as a graduation ceremony or concert. Additional features of the indoor facility include a recreational walking track suspended 14 feet in the air, an athletic training and rehab center, and a food court.
The Finley Center sits on a 120 acre site that GMC master planned and includes fields for soccer, lacrosse, football, baseball and softball, tennis courts, a play ground walking track and splash pad.
Goodwyn, Mills and Cawood (GMC) provided master planning, architecture, interior design, civil engineering, construction materials testing, and environmental engineering services for this project.

I went for a visit to Derby for their comedy festival and to spend the weekend with Gemma.
Saturday morning we went to Belper to the river gardens and the horseshoe weir, which is an incredible piece of civil engineering!
The gardens are lovely and tranquil. It was a great little alternative to our usual trip to Dovedale - which we called off because the weather wasn't great.
Had a lovely morning though!

The Salginatobel Bridge looks as if it belongs in its magnificent setting. It is not an intrusion, but it is an elegant, serviceable, important structure
- James E. Sawyer, PE, ASCE President The Salginatobel Bridge, 1991
The Salginatobel Bridge, spanning the Salgina Valley ravine, is the earliest surviving three-hinged, hollow box arch bridge designed by Robert Maillart.
Maillart's 1901 invention of the concrete hollow box design became a major bridge building concept. In this design, the concrete arch ring and the concrete deck are joined by longitudinal concrete sidewalls, giving the structure the cross-section of a hollow box. The bridge includes reinforcement in both the spandrel (pillar) walls and the arch to control cracking. The rocky walls of the ravine provide the arch support, obviating the need for stone abutments.
Maillart's design ran contrary to the prevailing view that bridges should be massive. He believed massive structures would more easily crack and shrink from temperature fluctuations. He also believed in using the best materials, but using them sparingly. This bridge underscores his view, providing the lowest cost of 19 designs submitted for the bridge's original design competition.

Detroit, Michigan, United States to Windsor, Ontario, Canada
Constructed 1928-1930
[It is] almost incredible that we will be able to pass from the one great country to the other in the short space of three minutes.
- Frank Murphy Mayor of Detroit, 1930
The Detroit-Windsor Tunnel is a 5,160-foot structure that carries traffic under the Detroit River between Detroit, Michigan and Ontario, Canada. Privately financed, built, and owned, it was completed in 26 months, 10 months ahead of schedule.
The project's engineer, the firm of Parsons, Klapp, Brinckerhoff and Douglass, used three tunneling methods to construct the structure: cut and cover for the land sections; compressed air shield for the channel approaches and trench; and immersed tube for the river sections. This combination of techniques permitted a shallow tunnel profile which, together with a spiral approach ramp, allowed the connection to Detroit's street system to be located just two blocks from the river.
Ventilation towers rise about 100 feet at each end of the tunnel, on 50-by-90-foot sites. Each tower holds six fresh air fans and six exhaust fans, capable of cycling in a complete change of air every 90 seconds.
Facts
- Prefabrication of the nine tube comprising the 32-foot diameter main channel section involved 65 miles of arc welding !V the first major use of arc welding in tunneling history.
- The immersed sections involved sinking nine steel tubes, 35-feet in diameter, into a trench dug across the river bottom.
- The project pioneered the construction of screeded bed foundation (a technique to ensure proper leveling of poured concrete) for the immersed tube sections.
- The maximum depth of the tunnel is 75 feet below the Detroit River.
- Two million granite blocks were used to pave the original roadway through the tunnel. These were removed when the roadway was paved with asphalt in 1977.

Engineered by Crouch & Hogg and built by Sir William Arrol & Co. in 1938.
Crouch & Hogg were formed by William Crouch & Charles Pullar Hogg in Glasgow in 1876. Amongst other projects, they were structural engineers of the
Glasgow Empire Exhibition Tower.
Sir William Arrol & Co. were founded in Glasgow in 1873 and were responsible for building some of the most famous bridges in the UK, most notably the Forth Bridge and Tower Bridge in London. The company was acquired by Clarke Chapman in 1969.
Camptonville, California
Invented 1878
Water wheels have been used to power mills and pumps for centuries. However, the traditional water wheel was inefficient: water hitting a bucket would splash back against the next bucket, slowing the wheel. This is especially true when water is delivered to the buckets under very high pressure.
Millwright Lester A. Pelton worked in the Mother Lode region during California's gold-mining era, where innovative miners had learned to concentrate a stream of water under very high head, through a nozzle and against banks of dirt and gravel in a process called hydraulic mining. Pelton experimented with high-head nozzles and water wheels, tinkering with at least 40 different configurations until he developed a split bucket water wheel.
Pelton's impulse water wheel was a key to tapping the vast waterpower of the mountainous American West. The Pelton wheel is still used throughout the world for generating power where sources of high-head water are available.
Facts
- The amount of power that a water wheel can generate from a stream of water is dependent on several variables, including: 1) the efficiency of the water wheel; 2) the volume of the stream of water; and 3) the pressure, or head, under which the water is delivered to the wheel. Thus, a high-head, low-volume hydropower facility can theoretically generate as much power as a low-head, high-volume facility.
- By splitting the stream of water from the nozzle into two parts, he was able to eliminate inefficiencies caused by water splashing back against other buckets. He also learned that by changing the angle of the water's impact against the buckets, he could control the speed and power of the water wheel.
- Within 15 years of its first serious demonstration at the Idaho-Maryland gold fields in 1880, 850 companies were using the Pelton wheel and many more were vying for orders.
- At the North Star Mine powerhouse in Grass Valley, California, an 18= foot Pelton Wheel, weighing 10,000 pounds, ran for 30 years pumping 1,000 gallons of water every minute from the mine.
- The wheels are typically used where water is under high heads, generally 1000 feet or more. They develop efficiencies up to 90 percent while utilizing small volumes of water compared to that which are used in turbines. Although there are some Pelton wheels operating under heads of even more than 2,000 feet, there are also many operating at heads of only several hundred feet.
- Pelton's hydraulic prime mover, known as a Pelton turbine, is still being manufactured at a scale and in sizes far beyond the original machines.
