Joshinetsu Expressway This is the repair work for the "Akari-san" tunnel between Usui Karuizawa IC and Saku IC (Out-bound line).

Since the lower part of the tunnel is damaged and the pavement surface is being damaged, full-scale repair work will be carried out before the traffic is affected.

By reinforcing the lower part of the tunnel body, the structure of the tunnel is strengthened, and damage to the paved road surface is repaired to improve safety.

We ask for your understanding and cooperation so that our customers can use the Expressway safely.
