On the 28th, Gunma Prefecture presented a policy at the prefectural assembly that the most likely route for the Ota-Kiryu Line Bypass, which connects Ota and Kiryu, is to build a tunnel in a straight line through the Hachioji Hills.
The bypass is planned to connect the Ota-Go-Do Smart Interchange on the Kita-Kanto Expressway with the Matsubara Bridge area on National Route 122 in Kiryu, and is expected to improve access between the two cities once completed.
The prefecture compared the route over the hills with the tunnel plan, and determined that the tunnel route, which is more expensive, is more cost-effective because it reduces travel time.
It is aiming to complete the plan by fiscal 2029."
