When Route 57 (Tatsuno, Minamiaso-mura) cannot pass by large-scale slope collapse caused by Kumamoto earthquake, it becomes, and, in prefectural Northern Hokkaido outer rim of a volcanic crater Otsu line (popular name milk road) and prefectural road Akamizu, Kikuchi line, it is in main detour to the Aso area.
Because sharp curve includes consecutive sections, and this detour is located again in place of high altitudes, we need road safety, traffic jam measures and the snow, freeze measures for the winter season with increase of traffic.
Therefore, we push forward maintenance of road lighting for the purpose of night safe security.
In early place, it turns on from the night of November 17 and starts, and all 22 road lightings to plan turn on by the end of November.
About securing of traffic such as milk roads, we will work sequentially in cooperation with country.
