Central Circular Route (Shuto Expressway)

From Wikipedia, the free encyclopedia

The Central Circular Route, signed as Route C2, is one of the routes of the Shuto Expressway system serving the central part of the Greater Tokyo Area. The route is a circumferential highway running through the outer wards of Tokyo. The complete route is 48.8 km in length, and now 36.4 km length is currently running. The last 12.4 km has been constructed. The currently existing portion goes through the wards of Edogawa, Katsushika, Adachi, Kita, Itabashi, Toshima, Shinjuku, Nakano, and Shibuya. The Yamate Tunnel opened to traffic on December 22, 2007. The extension of Yamate Tunnel between Route 4 and Route 3 is expected to be completely open sometime in 2009. The last 9.4 km through Meguro and Shinagawa is still under construction; this final segment of C2 is expected to be completed sometime in fiscal year 2013. When complete, C2 will begin and end at the Bayshore Route, which will serve to close the loop.
