The Ken-O Expressway (圏央道 Ken-Ō Dō?), or Metropolitan Inter-City Expressway (首都圏中央連絡自動車道 Shuto-ken Chūō Renraku Jidōsha-dō?), is a partially-completed ticket system toll expressway in Japan, owned and operated by the Central Nippon Expressway Company and East Nippon Expressway Company. In conjunction with the Tokyo Wan Aqua-Line and the Bayshore Route of the Shuto Expressway, it will form a full outer ring road of Tokyo. It is assigned the national highway Route 468 number.
Portions of the existing Yokohama-Yokosuka Expressway, Shin-Shonan Bypass and Chiba-Togane Road and the planned Yokohama Ring Expressway will be incorporated into the road.
The section owned by the Central Nippon Expressway Company runs from the east end of the Shin-Shonan Bypass west along the bypass and north to interchange 42. The rest is owned by the East Nippon Expressway Company.
[edit] Route description
The expressway will begin at the south end of the Bayshore Route in Yokohama, where it will head west on the existing branch of the Yokohama-Yokosuka Expressway to that road's main line. At the junction with the main line, the current expressway ends; ramp stubs are present to continue the road west. It will split from the planned Yokohama Ring Expressway and continue west to the east end of the Fujisawa Bypass (part of Route 1). An upgrade of that road will take it to the existing Shin-Shonan Bypass, an expressway, which it will split from as that road turns towards the south.
The Ken-O Expressway will then head north, crossing the Tomei Expressway and Chūō Expressway. North of the latter road, the present expressway begins, heading north and northeast to the junction with the Kan-Etsu Expressway. There it will continue east across the Tohoku Expressway and Joban Expressway; a short piece from the Joban Expressway east to the next interchange has been opened. It will turn southeast, crossing the Higashi-Kanto Expressway east of Narita Airport, and then running south to the present end of the Chiba-Togane Road, a two-lane expressway. Where that road abruptly turns west, the Ken-O Expressway will continue south, looping west to and at the junction of the Tokyo Wan Aqua-Line and Tateyama Expressway.
