In Japan, the Kanmon Roadway Tunnel (関門国道トンネル, kanmon kokudō tonneru) carries National Route 2 under the Kanmon Straits.[1] At the time of its construction, it was the longest undersea road in the world.[citation needed] It opened in 1958. The overall length is 3,461 meters, and it is 58 meters below sea level at the deepest point.[citation needed] The endpoints are in Shimonoseki, Yamaguchi and Moji-ku, Kitakyūshū.[1]
Work on the Kanmon Roadway Tunnel began in 1937, but was halted in 1939 by World War II. Work resumed in 1952, and the tunnel was officially opened on March 9, 1958. The event was marked by a Japanese commemorative postage stamp. Major repairs were conducted in 2008.
Under terms of Article 46.3 of Road Act, driving by vehicles that carry dangerous goods are either prohibited or limited strictly.
