no, it is IMHO not similar to low water crossing, being the latter
usually short while a tidal road will be often some kilometres long,
so the danger is really not comparable.

IMHO a road which is frequently flooded has this as a characteristic
(you can also see this because they got their own name in language)
while a road where you might expect heavy snowfall in winter is not
comparable, it still is a road (the snowfall IMHO is not a
characteristic of the road, while beeing flooded every day for some
hours IMHO is).
