Usage Statistics Approximately 6 Months After Launch

To further develop the Tama region, the Tokyo Metropolitan Government is promoting the development of regional arterial roads that, together with the backbone arterial roads, form the road network and contribute to ensuring smooth regional traffic flow and improving disaster resilience and safety.
On Metropolitan Road No. 250 (Akiruno-Hamura Line),a section of approximately 1.2 kilometers—stretching from Major Regional Road No. 7 (Suginami-Akiruno Line, near the Akigawa Farmers’ Center) to General Metropolitan Road No. 165 (Ina-Fussa Line, at the Hiyosawa Bridge intersection)—was provisionally opened on October 29, Reiwa 7.
