Sakura-Kobashi Bridge is an 87.8 m long pedestrian bridge which crosses Asashio Canal, a historic waterfront in Tokyo, and its construction was completed in October 1, 2017.


It is one of the planned bridges to increase accessibility to the Tsukishima, Kachidoki and Harumi Districts, to ease congestion on the pavements along Harumi Street, and to provide a disaster evacuation route. A comprehensive design approach was adopted for the bridge, involving not only the bridge itself but also the spaces at the bridge ends and connected streets to ensure accessibility to neighbouring areas as well as canal-side spaces, creating an attractive waterfront.


Taking the advice of the reviewing committee and the requests of local residents, the planning of the ward office and design team prioritized the privacy of nearby residents, improved attractiveness of the adjacent housing areas and an universal design throughout in addition to increased accessibility.


In regard to the bridge proper, it was necessary to satisfy various constraints. For example, the positions of the piers must provide for the navigation width of Asashio Canal, sustainable height clearance for the safe passage of boats using the canal and housing of 12 pipelines for power cables. Another constraint was the limited space for the construction work. Various designs were considered to achieve a silhouette of the appearance of gently floating thin girders in view of the design requirement of enhancing the waterfront attractiveness.


The prize awarding ceremony took place publicly on January 15, 2020 at the lecture hall of the JSCE in Tokyo..
