Multi Span Single Lane Steel Box Girder Bailey Bridges

Bridges constructed using this method are called Steel Box Girder Bridge. Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.

Lecture 15B.12: Introduction to Bridge - UL

9;7 Box Girder Bridges; Fabrication procedures for moderate size boxes, e;g; Siboulet Viaduct, Figure 7, are similar to those used for built_up plated girders for a composite bridge; Box girders necessitate welding of the highest quality; Long runs of automatic submerged arc welding should be used to connect webs and flanges;

Multi Span Single Lane Steel Box Girder Bailey Bridges

For steel box girders- the girders are normally fabricated off site and lifted into place by crane- with sections connected by bolting or welding. If a composite concrete bridge deck is used- it is often cast in-place using temporary falsework supported by the steel girder.Either form of bridge may also be installed using the technique of incremental launching.
