Yokohama Northwest Route

The, signed as Route K7, is one of the tolled routes of the Shuto Expressway system serving the Greater Tokyo Area and is one of seven of the routes in the system serving Kanagawa Prefecture. The route is a 8.2sp=usNaNsp=us long expressway running west from the northern terminus of the Daikoku Route at a junction with the Yokohane Route in Tsurumi-ku, Yokohama, to the Daisan Keihin Road in Tsuzuki-ku, Yokohama in Kanagawa Prefecture. Alongside the Daikoku Route, it connects northern Yokohama to the region-spanning Bayshore Route.

Route description

The Yokohama North Route begins at Namamugi Junction with the Yokohane and Daikoku routes in Tsurumi Ward near the mouth of the Tsurumi River. From there it travels west through Tsurumi where it enters a tunnel that carries the majority of the length of the expressway. At the eastern entrance to the tunnel the expressway has a partial interchange with National Route 1. The tunnel, named the Yokohama-kita Tunnel, is a 5.9sp=usNaNsp=us long, twin-bore tunnel that travels at a maximum of 40m (130feet) below the surface.[1] At the western entrance to the tunnel there is another interchange, this one is with Kanagawa Prefecture Route 13. This is also the point where the ramps to and from the Daisan Keihin Road begin and end. The expressway terminates at that highway, but also has access to the local streets in the Tsuzuki Ward where it ends.[2]

The speed limit along the entire length of the Yokohama North Route is set at 60 km/h.[3]
