This is similar to a low water crossing:

I don't think we use any special highway=* tags for those, or for other 
roads that may be dangerous at times (e.g. heavy snow, military proving 
grounds). If someone ignores signs and physical conditions, it's not our 
fault, and we shouldn't tag incorrectly to get routing software to 
ignore these roads.
