| has gloss | eng: A girder bridge, in general, is a bridge built of girders placed on bridge abutments and foundation piers. In turn, a bridge deck is built on top of the girders in order to carry traffic. There are several different subtypes of girder bridges: * A rolled steel girder bridge is made of I beams that are rolled into that shape at a steel mill. These are useful for spans between 10 meters and 29.5 meters (33 feet to 100 feet). Rolled steel girders are practically available with a web height of up to one meter (3 feet). * A plate girder bridge is made out of (mostly) flat steel sections that are later welded or otherwise fabricated into an I beam shape. Plate girders can have a greater height than rolled steel girders. Plate girder spans can be used for spans between 10 meters and more than 100 meters (33 feet to more than 330 feet). |
