A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements, typically straight, may be stressed from tension, compression, or sometimes both in response to dynamic loads. There are several types of truss bridges, including some with simple designs that were among the first bridges designed in the 19th and early 20th centuries. A truss bridge is economical to construct primarily because it uses materials efficiently.
The Jamestown Bridge was a cantilever truss bridge that connected Conanicut Island to mainland North Kingstown, Rhode Island, spanning the West passage of Narragansett Bay. The bridge first opened to traffic in 1940, replacing ferry service as the primary connection for the town of Jamestown, situated on Conanicut Island. It was constructed for just over $3 million 1940 USD, which was paid for by tolls until June 28, 1969. With a total length of 6,892 feet, the Jamestown Bridge was the third longest in Rhode Island at the time of its destruction, ranking behind its replacement, the adjacent 7,350-foot Jamestown Verrazzano Bridge, and the 11,248-foot Claiborne Pell Newport Bridge connecting Conanicut Island to Aquidneck Island and Newport. The Jamestown Bridge was closed to vehicular traffic on October 8, 1992, and its main span was destroyed through a controlled demolition on April 18, 2006.
The Fort Madison Toll Bridge is a tolled, double-decked swinging truss bridge over the Mississippi River that connects Fort Madison, Iowa, and unincorporated Niota, Illinois. A double-track railway occupies the lower deck of the bridge, while two lanes of road traffic are carried on the upper deck. The bridge is about 1 mile (1.6 km) long with a swing span of 525 feet (160 m), and was the longest and largest double-deck swing-span bridge in the world when constructed in 1927. It replaced an inadequate combination roadway/single-track bridge completed in 1887. The main river crossing consists of four 270-foot (82 m) Baltimore through truss spans and a swing span made of two equal arms, 266 feet (81 m) long. In 1999, it was listed in the National Register of Historic Places under the title, Fort Madison Bridge, ID number 99001035. It was also documented as survey number IA-62 by the Historic American Engineering Record, archived at the Library of Congress. Construction and photographic details were recorded at the time in Scientific American magazine.
The Coraopolis Bridge[1] is a girder bridge over the back channel of the Ohio River connecting Grand Avenue on Neville Island to Ferree Street in Coraopolis, Pennsylvania. It opened in 1995 to replace a structure of historic significance. The original Pratt/Bowstring/Pennsylvania[2] through truss spans, designed by Theodore Cooper, were formerly the (third) Sixth Street Bridge, spanning the Allegheny River, in downtown Pittsburgh, and were built in 1892 by the Union Bridge Company. They were floated downstream by the Foundation Company in 1927 rather than being demolished when the bridge was removed to enable construction of the present (fourth) Three Sisters (Pittsburgh) Sixth Street Self-anchored suspension bridge. However, by the late 1980s, the old bridge could no longer support traffic volumes and was replaced by a newer structure.
The Uhlerstown–Frenchtown Bridge is a free bridge over the Delaware River, owned and operated by the Delaware River Joint Toll Bridge Commission. The bridge connects New Jersey Route 12 in Frenchtown of Hunterdon County, New Jersey with Pennsylvania Route 32 in Uhlerstown of Bucks County, Pennsylvania.

The South Omaha Veterans Memorial Bridge was a continuous warren through truss bridge over the Missouri River connecting Omaha, Nebraska with Council Bluffs, Iowa via U.S. Highway 275.
The Miami Bridge, also known as the McDaniel Memorial Bridge, is a new concrete girder bridge that was built to replace a cantilever through truss bridge over the Missouri River at Miami, Missouri between Saline County, Missouri and Carroll County, Missouri. The Miami Bridge carries Route 41. The Miami Bridge was built in 1939, and its deck was replaced in 1983 as part of a rehabilitation project. The old bridge's main cantilever span was 474.7 feet, while the two anchor spans were each 415 feet in length, resulting in a total cantilever truss length of 1304.7 feet. There were 11 approach spans, including four Warren deck truss spans, three on the northern approach and one on the southern approach. All remaining approach spans were steel stringer (multi-beam/girder) spans. Total bridge length including approach spans is 2,071.9 feet. The bridge's deck width is 23.0 feet and it has vertical clearance of 16.5 feet.
B & O Railroad Viaduct is a historic structure in Bellaire, Ohio, listed in the National Register of Historic Places on June 22, 1976.
The 1950 Tacoma Narrows Bridge is a suspension bridge in the U.S. state of Washington that carries the westbound lanes of Washington State Route 16 across the Tacoma Narrows strait, between the city of Tacoma and the Kitsap Peninsula. Opened on October 14, 1950, it was built in the same location as the original Tacoma Narrows Bridge, which collapsed due to a windstorm on November 7, 1940. It is the older of the twin bridges that make up the Tacoma Narrows Bridge crossing of the Tacoma Narrows, and carried both directions of traffic across the strait until 2007. At the time of its construction, the bridge was, like its predecessor, the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and George Washington Bridge; it is now the 46th-longest suspension bridge in the world.
The Kettle Falls Bridges is the collective name for a pair of steel cantilever bridges carrying State Route 20/U.S. Route 395 and the Kettle Falls International Railway across the Columbia River at Kettle Falls, Washington. The south bridge carries motor vehicle traffic while the similar northern span is used for rail.
The Jackson Branch Bridge No. 15, also known as the Tecumseh Railroad Bridge due to its close proximity to the city of Tecumseh, is a historic railway deck truss bridge that spans the River Raisin in rural Raisin Charter Township in Lenawee County, Michigan.

The bridge is also noted for its decorative finials on top of the towers. With its eastern end located on Route 2 in West Virginia, between Follansbee and Wellsburg, it was also a popular route for foot traffic from Follansbee and Wellsburg to Mingo Junction in Ohio. Streetcar service was provided on the West Virginia side to the steps leading to the footpath along the bridge.
