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.

The Hart Bridge is a continuous, cantilevered truss bridge with an unusual design that includes a suspended road deck on the 332-metre (1,088 ft) main span and a through truss deck on the adjacent approach spans. Some notable continuous truss bridges, with main span lengths.
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).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.
The Patroon Island Bridge is a multi-span deck truss bridge that spans the Hudson River in Albany and Rensselaer in the state of New York. A major crossing, it carries Interstate 90 in the east–west direction between Albany and Rensselaer Counties. It has been in service since 1968, with structural repairs made in 1992, and a comprehensive ...
The Southern Pacific Railroad bridge in Tempe, Arizona is a 393 meter (1,291 foot) long truss bridge built in 1912. [22] [23] The structure is composed of nine Pratt truss spans of varying lengths. The bridge is still in use today.
The 1962 built, World's Longest, Single Span, Wooden Covered Bridge at Bridgeport State Park, California, uses a Burr-Arch in combination with the Howe-Truss to achieve this over 210' span. The only maintenance a Howe truss requires is adjustment of the nuts on the vertical posts to equalize strain. [ 1 ]
Like for multi-span continuous beam bridges the tying chord continually spans over all piers. The arches feet coincide (fuse) at the bridge piers. A good visual indication are shared supports at the piers. Dynamic loads are distributed between spans. This type may be combined with the shouldered tied-arch design discussed above.
