The Hida tunnel is opened on July 5, 2008.The Hida tunnel is as a part of Tokai Hokuriku Expressway. The tunnel is used by the selective exhaustion system. A selective exhaustion system can choose the position of the optimal concentrated exhaust port in the tunnel of facing traffic according to traffic ratio. A selective exhaustion system is effective especially in the route with big deviation in traffic ratio. The Hida tunnel exceeds over 10km, has ventilation stations at both portals, and uses side duct or lower section as exhaustion duct. In many cases, there is no secondary lining of the side duct in the Hida tunnel. Then, we measured the wall friction loss of the side duct.
