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 box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete , structural steel , or a composite of steel and reinforced concrete .
By the 1960s, prestressed concrete largely superseded reinforced concrete bridges in the UK, with box girders being the dominant form. [41] In short-span bridges of around 10 to 40 metres (30 to 130 ft), prestressing is commonly employed in the form of precast pre-tensioned girders or planks. [42]

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 ...
Prestressed concrete is a major advance in concrete engineering and has effectively been used in rigid frame bridge construction. [10] This is notable because it was already challenging to place standard reinforcing in a concrete rigid frame bridge. Prestressing the rebars is more difficult but was proven to still be feasible.
