Trans-Tokyo Bay Highway

Trans-Tokyo Bay Highway, a 15 km road link between Kawasaki City on the Tokyo side and Kisarazu on the other side of Tokyo Bay, consists of two tunnels, two manmade islands and a bridge. Bold engineering solutions have been applied on a large scale in the design and construction of the TTB Highway. The TTB Highway thus forms a gateway to the capital region, and aesthetic considerations were given careful attention in its design. This paper focuses on the design of two of the main structures of the TTB Highway, the bridge and the ventilation towers on the manmade Kawasaki Island.
