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 may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
The Cooper River is a mainly tidal river in the U.S. state of South Carolina. The cities of Mt. Pleasant, Charleston, North Charleston, Goose Creek, Moncks Corner, and Hanahan are located along the river. Short and wide, the river is joined first by the blackwater East Branch and then farther downstream at the tidal Wando River. Almost immediately thereafter, the Cooper River widens into its estuary and unites with the Ashley River to form the Charleston Harbor.
Interstate 526 (I-526) is a 19.56-mile (31.48 km) auxiliary route of I-26, providing a partial beltway around Charleston, South Carolina, in the United States. The route serves several purposes, firstly, as a bypass for through traffic on U.S. Route 17 (US 17) to avoid downtown Charleston, and, secondly, for traffic on I-26 bound for the coastal towns located north and south of Charleston. The route is not yet complete, as the western terminus it is planned for the route to be extended an additional 10 miles (16 km). After the eastern terminus, the roadway continues as a short business route, known as Interstate 526 Business.
The North Charleston Coliseum is a multi-purpose arena in North Charleston, South Carolina. It is part of the North Charleston Convention Center Complex, which also includes a performing arts center and convention center. It is owned by the City of North Charleston and managed by ASM Global. The coliseum opened in 1993, with the performing arts center and convention center opened in 1999.

The Arthur Ravenel Jr. Bridge is a cable-stayed bridge over the Cooper River in South Carolina, US, connecting downtown Charleston to Mount Pleasant. The bridge has a main span of 1,546 feet (471 m), the third longest among cable-stayed bridges in the Western Hemisphere. It was built using the design–build method and was designed by Parsons Brinckerhoff.
The Fred Schwengel Memorial Bridge is a 4-lane steel girder bridge that carries Interstate 80 across the Mississippi River between LeClaire, Iowa and Rapids City, Illinois. The bridge is named for Fred Schwengel, a former U.S. Representative from Davenport, Iowa and one of the driving forces behind the Interstate Highway Act. The structure was designed by the Iowa State Highway Commission, and was built by the Industrial Construction Company of Minneapolis (contractor), Gould Construction Company of Davenport, and Roy Ryan & Sons of Evanston, Indiana who was responsible for the substructure. The bridge opened on October 27, 1966, and is maintained by the Illinois Department of Transportation. It underwent a major rehabilitation project in 1996.
The John P. Grace Memorial Bridge, or the Cooper River Bridge as it was familiarly known, was a cantilever bridge that crossed the Cooper River in Charleston, South Carolina. It opened on August 8, 1929, and was built by the Cooper River Bridge Company. Shortridge Hardesty of Waddell & Hardesty, a New York City-based engineering firm, designed the bridge.
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
The Don N. Holt Bridge is a parallel chord, three-span continuous, modified Warren-type truss bridge that carries Interstate 526 (I-526) over the Cooper River between Charleston and North Charleston.

The John F. Limehouse Memorial Bridge, located about 15 miles (24 km) west of downtown Charleston, South Carolina, was completed in 2003. It replaced an obsolete low-level swing bridge over the Stono River. The current bridge, which crosses a channel between Johns Island and St. Andrews Parish, an area generally called West Ashley, was completed under a partnership between the South Carolina Department of Transportation (SCDOT) and the United States Coast Guard.
The Ben Sawyer Bridge is a swing bridge that connects the town of Mount Pleasant with Sullivan's Island in South Carolina. The bridge swings on its central axis to open for boat traffic which is too tall to clear the bridge, and has an operator's house in the center of the swing span from which a tender can operate the bridge. The bridge was originally constructed in 1945, but the steel superstructure for the approach spans and swing span was replaced in 2010, albeit retaining the same general appearance.
In the U.S. state of South Carolina, U.S. Route 17 (US 17) is a 221.454-mile (356.396 km) north–south U.S. Highway located near the Atlantic Ocean. The highway enters the state from Georgia at the Savannah River and serves Hardeeville, Charleston, Georgetown, and Myrtle Beach, before entering North Carolina near Calabash.
The Yadkin River Bridges are bridges crossing the Yadkin River between Rowan and Davidson Counties near Spencer, North Carolina in the United States. The northbound span of the Yadkin River Veterans Memorial Bridge, the first of two carrying Interstate 85 / U.S. Highway 52, opened May 5, 2012, and on August 2, 2012, southbound traffic moved to that span as well. A southbound span of the same bridge was completed in October 2012 and opened to traffic in March 2013. Each span carries four lanes of traffic.
The Tappan Zee Bridge, officially named the Governor Mario M. Cuomo Bridge, is a twin cable-stayed bridge spanning the Hudson River between Tarrytown and Nyack in the U.S. state of New York.

The new bridge's north span carries the northbound and westbound automobile traffic of the New York State Thruway, Interstate 87 (I-87) and I-287; it also carries a shared use path for bicycles and pedestrians. The south span carries southbound and eastbound automobile traffic.
