ABSTRACT:
A cable-stayed girder bridge having a concrete deck girder which includes longitudinally extending stiffening girders having cables embedded therein and a laterally extending deck portion is constructed by sequential formation of said deck girder in successive adjacent sections. The longitudinally extending stiffening girder portions of said deck girder are first formed, support cables are embedded therein and subsequently tensioned. After hardening of the stiffening girders, the laterally extending deck portion of the duck girder is formed. A form carrier movable along the bridge during its construction extends in a cantilevered arrangement from a previously formed deck girder section to provide support for a successive deck girder section during formation thereof.
