ABSTRACT:
A method of constructing the approach and main spans of a cable stayed segmental bridge as the main span is constructed as a smooth continuation of the approach spans without the need for special equipment or different box girder deck sections. The approach spans are constructed each in succession from opposite sides of the main span after which the main span continues from opposite sides toward a midpoint, while the cable stays are installed. For a two-wide box girder bridge, delta frames interconnect side-by-side box girders at the anchor locations of the cable stays for thereby transferring the static and dynamic loads of the main span toward the center plane of support of the cable stays.
