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.
Friendship Hill was the home of early American politician and statesman Albert Gallatin (1761–1849). Gallatin was a U.S. Congressman, the longest-serving Secretary of the Treasury under two presidents, and ambassador to France and Great Britain. The house overlooks the Monongahela River near Point Marion, Pennsylvania, about 50 miles (80 km) south of Pittsburgh.
The Three Sisters are three similar self-anchored suspension bridges spanning the Allegheny River in downtown Pittsburgh, Pennsylvania at 6th, 7th, and 9th streets, generally running north/south. The bridges have been given formal names to honor important Pittsburgh residents:
The Smithfield Street Bridge is a lenticular truss bridge crossing the Monongahela River in Pittsburgh, Pennsylvania, USA.
The Monongahela Incline is a funicular located near the Smithfield Street Bridge in Pittsburgh, Pennsylvania. Designed and built by Prussian-born engineer John Endres in 1870, it is the oldest continuously operating funicular in the United States.
The Homestead Grays Bridge, also known as the (Homestead) High Level Bridge, was built in 1936 and spans the Monongahela River between Homestead Borough and the southernmost tip of Pittsburgh's Squirrel Hill neighborhood. It is notable as the first bridge to incorporate the Wichert Truss, which uses a quadrilateral shape over each support, into its design. This made the truss statically determinate, so that forces in the structural members could be calculated. There are very few surviving Wichert Truss bridges, including one other example in Pittsburgh, the Charles Anderson Memorial Bridge.
South Tenth Street Bridge, most often called the Tenth Street Bridge, but officially dubbed the Philip Murray Bridge, is a suspension bridge spanning the Monongahela River in Downtown Pittsburgh, Pennsylvania. It is the only cable suspension bridge in Allegheny County and its 725-foot (221 m) main span is the longest span on the Monongahela River. The bridge was renamed on Labor Day 2007 for Philip Murray, the first president of the United Steelworkers of America.
The West End Bridge is a steel tied-arch bridge over the Ohio River in Pittsburgh, Pennsylvania, approximately 1 mile (1.6 km) below the confluence of the Allegheny and Monongahela Rivers. It connects the West End to the Chateau neighborhood on the North Side of Pittsburgh.
George Westinghouse Memorial Bridge in East Pittsburgh, Pennsylvania, carries U.S. Route 30, the Lincoln Highway, over the Turtle Creek Valley near to where it joins the Monongahela River Valley east of Pittsburgh. The reinforced concrete open-spandrel deck arch bridge has a total length of 1,598 feet (487 m) comprising five spans. The longest, central span is 460 feet (140 m), with the deck height 240 feet (73 m) above the valley floor, for a time the world's longest concrete arch span structure. It cost $1.75 million. The design engineers were Vernon R. Covell and George S. Richardson, with architectural design by Stanley Roush. The pylons at the ends of the bridges feature Art Deco reliefs by Frank Vittor.
Pennsylvania Route 88 is a 68-mile-long (109 km) north–south state highway located in southwestern Pennsylvania. The southern terminus of the route is at U.S. Route 119 (US 119) in Point Marion less than 2 miles (3 km) from the Pennsylvania-West Virginia border. The northern terminus is at PA 51 in Pittsburgh. PA 88 runs parallel to the Monongahela River for almost its entire length.
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 Brownsville Bridge, also known as the Intercounty Bridge and the West Brownsville Bridge, is a truss bridge that carries vehicular traffic across the Monongahela River between Brownsville, Pennsylvania and West Brownsville, Pennsylvania. Since the opening of the Lane Bane Bridge and highway project to carry much of the intercounty through traffic away from the main streets of downtown Brownsville in the early 1960s, another commonly heard name is Old Brownsville Bridge for the four high level viaduct.
The Charleroi-Monessen Bridge, officially the John K. Tener Memorial Bridge, is a two lane structure spanning the Monongahela River. The bridge connects North Charleroi in Washington County, Pennsylvania and Monessen in Westmoreland County, Pennsylvania. The structure connects Route 88 on the west bank of the river and Route 906 on the east side. The bridge, which opened in 2013, replaced a 1906 structure. The original bridge was closed in 2009 due to structural deficiency.
The Point Bridge was a steel cantilever truss bridge that spanned the Monongahela River in Pittsburgh, Pennsylvania.
The Straight Street Bridge is a vehicular bridge over the Passaic River in Paterson, New Jersey, that is listed on the National Register of Historic Places.
The Charles Anderson Memorial Bridge is a steel deck truss bridge located in Pittsburgh, Pennsylvania, United States. The bridge carries the four-lane roadway of Boulevard of the Allies across a ravine known as Junction Hollow, connecting the neighborhoods of Central Oakland and South Oakland with Schenley Park. The bridge also spans the Junction Hollow Trail and P&W Subdivision railroad tracks which run along the bottom of the valley.
