Sugitani River Bridge (Westbound) is a 6-span corrugated steel web PC box girder bridge on New Meishin Expressway. It was constructed by balanced cantilever method. One of newly applied construction technologies is to make steel flanges continuous by connecting each member by splice plates. Precast panels are placed on the bottom steel flanges, which eliminated bottom slab formworks for cantilever construction.
The combination of continuous steel flanges and new travelers makes it possible to streamline works on cantilevers and greatly reduces construction period as well as improves durability.
