Suspension Bridges A suspension bridge is a type of bridge which is built by suspending the roadway from cables attached to a master cable which runs above the length of the bridge. They are strong and lightweight
The Golden Gate Bridge was the longest suspension bridge span in the world when it was completed in 1937
The Tower Bridge was opened on June 30, 1894 by The Prince of Wales
The Brooklyn Bridge is one of the oldest suspension bridges in the United States built in 1883
Arch Bridges An arch bridge is a type of bridge that relies on a curved, semi-circular structure for its support.
The Ponte Vecchio (literally old bridge) is a Medieval bridge over the Arno River in Florence; the only Florentine bridge to survive WWII
Sydney Harbor Bridge is the worlds largest (but not the longest) steel arch bridge with the top of the bridge standing 134 meters above Sydney Harbor
NY architecture firm Fxfowle is designing what will be the largest and tallest arch bridge in the world, at one mile long and 670 feet tall with a price tag of$817 million dollars.
Cable Stayed Bridges A cable-stayed bridge has one or more towers (or pylons), from which cables support the bridge deck
The Millau Viaduct (le Viaduc de Millau, in French) spans the River Tarn valley near the medieval town of Millau in southern France
Nanpu Bridge was made to minimize the amount of land used by the bridge approach
The Alamillo Bridge provides a vital transport link across the Guadalquivir River from the Spanish city of Seville to La Cartuja Island
Truss Bridges The basic truss design consists of three basic components: the piers, the chords and the diagonal "webs" that give the truss its distinctive, triangular-webbed appearance. More elaborate truss bridges may also sport struts, sway bracing and wind bracing
The design of the Bollman Truss Bridge- patented in 1852 and one of the first to use iron exclusively in all essential structural elements-was critical in the rapid expansion of American railroads in the 19th century
The Bridge on the River Kwai is a 1957 British-American World War II film. The film is based in Japan but the bridge is actually in Thailand
Beam Bridges A beam bridge, sometimes called a girder bridge, is a rigid structure that consists of one horizontal beam supported at each end, usually by some kind of pillar or pier.
The Manchac swamp bridge in Louisiana is the 2nd longest in the United States, which carries Interstate 55 across the swamps
The Tianjin Grand bridge is one of the youngest and also the second longest of all bridges and is a sea link
Tilt Bridge A tilt bridge is a type of moveable bridge which rotates about fixed endpoints rather than lifting or bending, as with a drawbridge
The Gateshead Millennium Bridge is the world's first and currently only tilting bridge
