Work to be done until the road closure due to rain is lifted

The road closure will be lifted once safety has been confirmed.
The rainfall so far has loosened the ground, increasing the risk of landslides. Therefore, after the rain has settled for a certain period of time, we will carry out inspections and work (restoration and cleaning), and once safety has been confirmed, the road closure will be lifted. We ask for your understanding and cooperation.
