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.

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.
The Anderson Bridge is a three-span steel deck truss bridge using the Wichert truss design developed and patented by Edward Martin Wichert (1883–1955). [11] This design behaves like a continuous truss in that the live load of vehicles is distributed across all three spans. Therefore less material is required than a simple truss where each ...
The various parts of a truss bridge. A deck is the surface of a bridge. A structural element of its superstructure, it may be constructed of concrete, steel, open grating, or wood. Sometimes the deck is covered by a railroad bed and track, asphalt concrete, or other form of pavement for ease of vehicle crossing.

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.
