Bridge structure

A bridge supports any desired loading capacity to cross rivers, ravines, highways, wetlands, and other areas where traffic or pedestrians conveniently access the opposite side. The structure is assembled in a number of ways at the bridge site, using smaller equipment and less time than is normally required. The prefabricated and trial fitted elements can be assembled at ground level and the structure can be launched on rollers across the area that is to be crossed, or can be assembled sequentially from one or both sides. The structure includes two or more box girders supporting the bridge deck which is integrated into the structure. The upper portion of the girders form the side barriers of the bridge and the deck with integrated cross members is fastened to the lower portion of the girders, both of which are sized to accommodate the load bearing capacity of the traffic using the structure.
