The stubs at the eastern end of the Dunn Memorial Bridge give a good cross section of girder bridge construction A rolled steel girder is a girder that has been fabricated by rolling a blank cylinder of steel through a series of dies to create the desired shape.
Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders are usually prefabricated and the length limit is frequently set by the mode of transportation used to move the girder from the bridge shop to the bridge site.

A view of the bridge from a commercial jet. In 1970, it won an award of merit for a long-span bridge from the American Institute of Steel Construction. [15] The five-lane bridge featured the longest continuous box girder in the world [12] until it was surpassed by the Shibanpo Yangtze River Bridge in Chongqing, China, in 2008. [16]

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 old Britannia Bridge with train track inside the box-girder tunnel Section of the original tubular Britannia Bridge The patent curved and tapered box girder jib of a Fairbairn steam crane. A box girder or tubular girder (or box beam) is a girder that forms an enclosed tube with multiple walls, as opposed to an Ɪ-or H-beam.

Royal Engineers construct a Bailey bridge in Italy, September 1943. Wood planks are being laid over the stringers to construct the roadbed. The success of the Bailey bridge was due to the simplicity of the fabrication and assembly of its modular components, combined with the ability to erect and deploy sections with a minimum of assistance from heavy equipment.
