Tokyo Bay (Rainbow) Bridge Project
Location: Tokyo, Japan
Client: Chodai Corporation Ltd.
A 798 m long, 29 m wide, double-deck suspension bridge designed for highway and new transit system.
The Tokyo Bay Bridge is a suspension bridge crossing northern Tokyo Bay between the Shibaura Wharf and the Odaiba waterfront development in Minato, Tokyo, Japan. Completed in 1993, the bridge spans 570 meters and carries three transportation lines on two decks. The roofs of the anchorages (foundations fixing the suspension bridge main cables) have a curved surface that aligns smoothly with the catenary line of the main cables, giving the bridge a graceful profile. The bearing layer of the bridge foundations consists of soft rock known as mudstone. Very few suspension bridges worldwide have their foundations on mudstone. Additionally, the bridge features one of the world’s largest pneumatic caisson foundations.
