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.
In the deck-type bridge, a wood, steel or reinforced concrete bridge deck is supported on top of two or more plate girders, and may act compositely with them. In the case of railroad bridges, the railroad ties themselves may form the bridge deck, or the deck may support ballast on which the track is laid.

A concrete deck may be an integral part of the bridge structure (T-beam or double tee structure) or it may be supported with I-beams or steel girders. When a bridge deck is installed in a through truss, it is sometimes called a floor system. [1] A suspended bridge deck will

Thousands of orthotropic deck bridges are in existence throughout the world. Despite the savings and advantages (up to 25% of total bridge mass can be saved by reducing deck weight, as the weight reductions extend to cables, towers, piers, anchorages, and so forth), the US has only about 60 such bridge decks in use as of late 2005.
The Hart Bridge spanning the St. Johns River in Jacksonville, Florida, is a continuous, cantilevered truss bridge which combines a suspended road deck on the 332-metre (1,088 ft) main span and through truss decks on the adjacent approach spans
The box girder, which functions as the deck of the bridge and carries the live load, comprises end diaphragm (1,000 millimetres (39 in) thick), which has inspection windows. [ 9 ] The design of the girder accounts for loading conditions of full span train load, half span train load, one third span train load and so forth with due accounting of ...
