About road inundation assumption point
Last Updated February 1, 2024
Contents
In order to prevent accidents and secure safe road traffic during local heavy rains, so-called guerrilla downpours, etc., we have published a "Road Flood Assumption Location Map".
Please share the information on the expected flooding area and ensure safe traffic during heavy rain.
・This is a compilation of "where the roadway has an underpass structure (*) and may be flooded during guerrilla downpours".
・We assume cases such as abnormal short-term heavy rain (local heavy rain, so-called guerrilla heavy rain), and there is no problem in road traffic with normal rain.
※An underpass is a road that crosses three-dimensionally with major arterial roads and railways, and refers to places where the height of the road is suddenly reduced (drilling part) compared to the front and rear.
Road flooding area (as of August 31, 2018)

During local heavy rains that occur frequently in recent years, roads may be flooded even in places other than the expected road flooding area. During heavy rains, pay attention to weather information and be careful when driving a vehicle.
