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 maintained live camera to confirm road-surface condition, and to strengthen collection function of road information. Picture of live camera releases in HP of Ministry of Land, Infrastructure, Transport and Tourism Kyushu district maintenance station Kumamoto river national highway office and Kumamoto from the midday of December 12.
At the same time, we maintained milepost every 100m to grasp correct positional information, and to promote quick correspondence in the case of notification of accident car and disabled vehicle generating.
About securing of traffic such as milk roads, we will work sequentially in cooperation with country.
