A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are ...
A similar bridge on this river was fabricated ashore and pushed across its pylons. Single box girder bridge , flyover above eastern approach of the San Francisco–Oakland Bay Bridge. A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box.
A concrete curved-chord through girder bridge, sometimes known as a camelback bridge, [2] [i] is a type of concrete bridge most common in the U.S. state of Michigan and the Canadian province of Ontario.

[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 ...
In some cases, the plate girders may be formed in a Z-shape rather than I-shape. The first tubular wrought iron plate girder bridge was built in 1846-47 by James Millholland for the Baltimore and Ohio Railroad. [2] Plate girder bridges are suitable for short to medium spans and may support railroads, highways, or other traffic. Plate girders ...
Concrete is the most popular structural material for bridges, and prestressed concrete is frequently adopted. [ 36 ] [ 37 ] When investigated in the 1940s for use on heavy-duty bridges, the advantages of this type of bridge over more traditional designs was that it is quicker to install, more economical and longer-lasting with the bridge being ...
