Structural Concrete Issue 02/15

Cover_suco_15-02.jpgCover Story: The New Tomei Expressway is located on the south-eastern coast of Honshu, Japan’s main island, and runs parallel to the existing Tomei Expressway. The new expressway alleviates traffic congestion on the old Tomei Expressway and improves accessibility of Japan’s three major cities. The here depicted Uchimaki Viaduct is one of 31 bridges using DYWIDAG systems in the New Tomei Expressway. (© DSI, see page A5)
