A girder bridge is a bridge that uses girders as the means of supporting its deck. [1] The two most common types of modern steel girder bridges are plate and box. [citation needed] The term "girder" is often used interchangeably with "beam" in reference to bridge design.
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.

The Martel bridge was adopted by the British Army in 1925 as the Large Box Girder Bridge. [2] A scaled down version of this design, the Small Box Girder Bridge, was also formally adopted by the Army in 1932. This latter design was copied by many countries, including Germany, who called their version the Kastenträger-Gerät (K-Gerät for short ...
Such modern bridges include girder, plate girder, and box girder bridges, all types of beam bridges. Types of construction could include having many beams side by side with a deck across the top of them, to a main beam either side supporting a deck between them. The main beams could be I-beams, trusses, or box girders.
A tubular bridge is a bridge built as a rigid box girder section within which the traffic is carried. [1] Famous examples include the original Britannia Bridge over the Menai Strait, the Conwy railway bridge over the River Conwy, designed and tested by William Fairbairn and built by Robert Stephenson between 1846 and 1850, and the original Victoria Bridge in Montreal.
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. [1] [2]: 85 [3] The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons ...
A Vierendeel bridge is a bridge employing a Vierendeel truss, named after Arthur Vierendeel, a Belgian engineer who proposed this new bridge girder-type without diagonals in 1896. [ 1 ] Such trusses are made up of rectangular rather than triangular frames, as are common in bridges using pin–joints .
