The Tokyo C1 city motorway ( Japanese 首都 高速 都 心 環状 線 , shuto kōsoku toshinkanjō-sen , "inner city ring line of the capital motorway [en]", English Shuto Expressway Inner Circular Route ) is a 15 km long motorway section of the Tokyo city motorway in the center the Japanese capital Tokyo . It runs as a closed ring through the districts of Chūō , Minato and Chiyoda , connected on the outside with lines 1 to 6 of the Tokyo city highway are the most important routes to the outer districts and to the national highways and inside the Yaesu line (Y) and the older one , Tokyo private highway . On street signs, the name of the motorway is abbreviated in Latin-Arabic with C1 (C for circular ) and in Japanese with 環 ("Ring") or 都 環 ("Hauptstadtring") and is sometimes marked with a circular arrow indicating the direction of travel.
In 1962 the first 4.5 km long section between the Kyōbashi and Shibaura junctions was opened to traffic. This was also the first stretch of the city motorway, which had been founded as a public company ( kōdan ) in 1959. Until the opening of the Summer Olympics in 1964 , most of the route sections were gradually opened; only the southwestern, almost four kilometer long section between Kasumigaseki and Shiba-Kōen was not navigable until July 1967.
To the west, where the ring runs close to the inner moat of today's Imperial Palace , it runs through the 1900-meter-long Chiyoda Tunnel under the Supreme Court and the National Theater. There are smaller tunnels in several places, in the northeast the motorway ring is an elevated road over the Nihombashigawa and thus also over the Nihombashi , a traditional symbol of Tokyo. This is where the transcontinental AH1 begins on the inner city ring and leaves it in the west via the Shibuya line (3) .
In the Kitanomaru Park in Chiyoda in 2005 over 120,000 vehicles used the motorway every day, in Hatchōbori in Chūō the figure was around 93,000.
