The Bayshore Route of Shuto Expressway (首都高速道路湾岸線, Shuto Kōsokudōro Wangan-sen or simply Wangan-sen for short) is a stretch of toll highway in Greater Tokyo, 70 km, that runs from Yokohama city, Kanazawa ward, to Ichikawa city of Chiba Prefecture. It is an important route that runs between artificial islands of Tokyo Bay by way of bridges and sub-sea tunnels, bypassing Tokyo entirely.
