Sarutagawa and Tomoegawa Bridge

Sarutagawa and Tomoegawa Truss Bridge was constructed through integrated PC method and are part of Shintoumei elevated highway. In terms of integrated truss bridge design, not only it has the largest span in the world, it also is the first of its kind to implement rigid frame design. Since the bridge structure is unusual, prior to the commencement of the construction, substantial amount of analyses and test were conducted in order to ensure an appropriate level of structure safety. By leveraging on accumulated past experience, we managed to simplify the construction of the main structure and improve upon the whole construction process for both inbound and outbound lane.
