List of longest continuous truss bridge spans

 

List of longest continuous truss bridge spans

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 ways. First by the length of main span (the longest length of unsupported roadway) and second by the total length of continuous truss spans.

This list includes bridges that act primarily as a continuous truss. These bridges may appear to be—or may incorporate elements of—a different design. For example, the list includes the Francis Scott Key Bridge which incorporates an arch shape into the design, but is continuous across multiple spans. The Key Bridge acts first as a continuous truss bridge and secondarily as an arch bridge. This list does not include cantilever bridges.

Only bridges that are currently in use are included in the rankings. Bridges currently being planned, designed, or constructed and bridges that have been demolished are noted separately.

List ranked by length of main span

The length of main span is the most common method of comparing the size of bridges. The length of the main span will often correlate with the depth of the truss (height the truss from bottom to top) and the engineering complexity involved in designing and constructing the bridge.

For bridges that have the same span length, the older bridge is listed first.

List ranked by total length

It is also possible to rank continuous truss bridges by the sum of the continuous spans.

Note that if the bridge has an expansion joint (a discontinuity), the sections of the bridge would be considered separate (by the definition of a continuous bridge) for the purposes of this ranking. The Yoshima Bridge is an example of this. It consists of two continuous-truss sections that together have five total spans. The first section (or unit) is 2-span continuous, 125 m + 137 m; the second section is a 3-span unit, 165 m + 245 m + 165 m.[1]
