Japan has over 270 km of road tunnels and constructs about 30 km each year on the normal highway system and the national expressway system. Traditional construction methods are being used in the Tsuruga and Yanagese road tunnels in the central area of the country. The rail tunnels in the same region include the 22 km-long Dai-shimizu tunnel which will run from Tokyo through the Tanigawa mountains. The author describes the design and construction methods used on the various tunnelling projects. /TRRL/
