SINKING A TUNNEL IN TOKYO BAY

The Tama River and Kawasaki Fairway Tunnel project is part of the Tokyo Bay Ring Highway system of roads, bridges, viaducts and tunnels that will link Tokyo and Yokohama, and will inlcude 160m (100 miles) of 10 to 14 lane roadway, including two traverseways across Tokyo Bay. Submerged tunnels were chosen for the project. The Tama River Tunnel, which will be the first, will use 12 concrete boxes (elements) and be 5085 ft long. The next tunnel will have 9 elements and be 3900 ft long. Each will have separate sections for 3 driving lanes in each direction plus passageways on either side for maintenance, emergency access, and for conveying gas and electrical service. These small side channels will be used as ballast tanks when the elements are placed. The elements are rigid reinforced concrete structures designed to be 100% watertight. The design and construction of the elements are described. Details of their placement are also given. The tunnels are expected to be in service in early 1995.
