A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
John Augustus Roebling was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark.
The John A. Roebling Suspension Bridge is a suspension bridge that spans the Ohio River between Cincinnati, Ohio, and Covington, Kentucky. When opened on December 1, 1866, it was the longest suspension bridge in the world at 1,057 feet (322 m) main span, which was later overtaken by John A. Roebling's most famous design of the 1883 Brooklyn Bridge at 1,595.5 feet (486.3 m). Pedestrians use the bridge to get between the hotels, bars, restaurants, and parking lots in Northern Kentucky. The bar and restaurant district at the foot of the bridge on the Kentucky side is known as Roebling Point.
High Bridge is an unincorporated community and census-designated place in Jessamine County, Kentucky, United States. As of the 2010 census it had a population of 242. It lies along the lower reaches of the Kentucky River across from the confluence of the Dix River with the Kentucky. The community is part of the Lexington–Fayette Metropolitan Statistical Area.
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
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 Ross Island Bridge is a cantilever truss bridge that spans the Willamette River in Portland, Oregon. It carries U.S. Route 26 across the river between southwest and southeast Portland. The bridge opened in 1926 and was designed by Gustav Lindenthal and honors Oregon pioneer Sherry Ross. It is named for its proximity to Ross Island. Although it looks like a deck arch bridge, it is a cantilever deck truss bridge, a rare type in Oregon.
The Niagara Cantilever Bridge or Michigan Central Railway Cantilever Bridge was a cantilever bridge across the Niagara Gorge. An international railway-only bridge between Canada and the United States, it connected Niagara Falls, New York, and Niagara Falls, Ontario, located just south of the Whirlpool Bridge, and opened to traffic in 1883, it was replaced by the Michigan Central Railway Steel Arch Bridge in 1925.
The Niagara Falls Suspension Bridge stood from 1855 to 1897 across the Niagara River and was the world's first working railway suspension bridge. It spanned 825 feet (251 m) and stood 2.5 miles (4.0 km) downstream of Niagara Falls, where it connected Niagara Falls, Ontario to Niagara Falls, New York. Trains used the upper of its two decks, while pedestrians and carriages used the lower. The bridge was the idea of Canadian politicians, and it was built by an American company and a Canadian company. It was most commonly called the Suspension Bridge, although other names included Niagara Railway Suspension Bridge, Niagara Suspension Bridge, and its official American name of the International Suspension Bridge.
Gustav Lindenthal was a civil engineer who designed the Queensboro and Hell Gate bridges in New York City, among other bridges. Lindenthal's work was greatly affected by his pursuit for perfection and his love of art. Having received little formal education and no degree in civil engineering, Lindenthal based his work on his prior experience and techniques used by other engineers of the time.
The Huey P. Long Bridge, located in Jefferson Parish, Louisiana, is a cantilevered steel through-truss bridge that carries a two-track railroad line over the Mississippi River at mile 106.1, with three lanes of US 90 on each side of the central tracks. It is several kilometers upriver from the city of New Orleans. The East Bank entrance is at Elmwood, Louisiana, and the West Bank at Bridge City.
The Roberto Clemente Bridge, also known as the Sixth Street Bridge, spans the Allegheny River in downtown Pittsburgh, Pennsylvania, United States.
The Purple People Bridge is a pedestrian-only bridge that stretches 2,670 feet over the Ohio River, connecting Newport, Kentucky to downtown Cincinnati, Ohio.
The Frisco Bridge, previously known as the Memphis Bridge, is a cantilevered through truss bridge carrying a rail line across the Mississippi River between West Memphis, Arkansas, and Memphis, Tennessee.
The Quincy Rail Bridge is a truss bridge that carries a rail line across the Mississippi River between West Quincy, Missouri, and Quincy, Illinois, USA. It was originally constructed in 1868 for the Chicago, Burlington and Quincy Railroad, a predecessor of BNSF Railway.
The Milton–Madison Bridge is a continuous truss bridge that connects Milton, Kentucky and Madison, Indiana. It carries approximately 10,000 cars a day. The old structure was replaced with a completely new continuous truss which was constructed on temporary piers adjacent to the operational span between 2011 and 2012 and slid into place after demolition of the old span using a construction method called "truss sliding." The new crossing opened to vehicle traffic in April 2014, and a pedestrian sidewalk opened that October.
Young's High Bridge is a former railroad bridge near Tyrone, Kentucky, USA, that spans the Kentucky River between Anderson County, Kentucky and Woodford County, Kentucky for the Louisville Southern Railroad. The cantilever bridge, named in honor of William Bennett Henderson Young, was constructed in 1889, and the first train crossed over on August 24, 1889. The bridge is 1,659 feet in length, is 283 feet above the river, and includes a 551 foot long cantilever span.
The Quechee Gorge Bridge is a historic bridge, carrying U.S. Route 4 (US 4) across Quechee Gorge, near the Quechee village of Hartford, Vermont. Built in 1911, it is Vermont's oldest surviving steel arch bridge. It was listed on the National Register of Historic Places in 1990.
The Fink truss is a commonly used truss in residential homes and bridge architecture. It originated as a bridge truss although its current use in bridges is rare.
