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 ...

The technique was further developed using epoxy on the joints along with pre-cast concrete segmental box-girder technology, which was applied in 1962 on the Choisy-le-Roi Bridge extending over the Seine River in Paris, France [2] In 1955 he began working for Campenon Bernard in Paris, France, where he worked with large pre-stressed concrete ...
Once several bridge piers are complete, support brackets are attached to adjacent piers and the main parallel girders of the MSS are lifted in place to support the scaffold and concrete forms. Jacks are used to raise the girders and forms and the concrete is poured for the segment (or span) after rebar is placed. After the concrete has cured ...

Multispan Plate girder bridge: deck type on concrete piers. Multispan plate-girder bridges may be an economical way to span gaps longer than can be spanned by a single girder. Spacing of piers between the abutments is dependent on the capacity of the selected plate girders. Separate plate girder bridges span between each pair of abutments in ...
