The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
A continuous truss bridge is a truss bridge that extends without hinges or joints across three or more supports. A continuous truss bridge may use less material than a series of simple trusses because a continuous truss distributes live loads across all the spans; in a series of simple trusses, each truss must be capable of supporting the ...
The bridge was initially over 270 metres (890 ft) long, although numerous shortenings over the years and river bank replenishments mean the bridge now totals only 204.7 metres (672 ft) long. It is the oldest surviving truss bridge in the world, consisting of strutted and triangulated trusses of moderate span, supported on piled trestles; as ...
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.
The bridge, which opened on 29 April 2009, is the world's longest through arch bridge. [2] The continuous steel truss arch bridge with tie girders has a height of 142 m (466 ft) from middle supports to arch top, main span of 552 m (1,811 ft) and a total length of 1,741 m (5,712 ft). It carries six lanes of traffic with a pedestrian walkway on ...
This is a list of the world's longest bridges that are more than 3 kilometers (1.9 mi) in length sorted by their full length above land and water. The main span is the longest span without any ground support.
The oldest surviving truss bridge in the world is the Kapellbrücke in Switzerland, first built in the 1300s. Modern-style timber truss bridges were pioneered in Switzerland in the mid-1700s. [9] Germany has 70 surviving historic wooden covered bridges. [10]
The Ikitsuki Bridge is a continuous truss bridge that connects Ikitsuki to Hirado Island. Completed in 1991, it has a main span of 400 meters (1,300 feet). [ 1 ] It is the longest continuous truss bridge in the world .
