Dive road
A diving road ( French chaussée submersible ) is a road that can only be used temporarily (at low tide) for vehicles. There are diving routes ( Mézilles ) that cross small rivers and passages that are only accessible on foot over streams and to islands ( Grand Bé , Tatihou , Île Tristan ). The road type replaces a bridge or a dam predominantly in Western Europe.
