Ayase River Mito Bridge

Ayase River Mito Bridge crosses Ayase River and is located in Katsushika ward, Tokyo. It is a post-tensioned T-girder bridge using corrugated steel web. Corrugated steel web replaces concrete web of conventional post-tensioned concrete T-girders, and reduces self-weight of the girders. It contributes to reduction of depth-span ratio and reduction of the number of girders necessary in the design.
P.S. Mitsubishi carried through various technical studies regarding design, production and erection, and realized the world first post-tensioned T-girder bridge using corrugated steel web.
