I meant: "No, the fact that it is sometimes closed by the tide should 
not be tagged separately from the type of road, because I am not talking 
about something that is 'basically a normal road just with an extra 
property'; I am talking about something that is not a normal road."

I see - I had this in mind:

http://wiki.openstreetmap.org/wiki/Proposed_features/Tidalflat_path

which refers to a certain type of path we have in Germany in the North 
Sea, where you basically walk on the (more or less) dry seabed.

Somewhat; I mis-interpreted your "closed" as if there was a gate or door 
somehow, when you probably just meant closed by being flooded.

In a way, the Lindisfarne Causeway looks like a normal road with just a 
few extra signs. OTOH the paths mentioned in the tidalflat_path proposal 
probably don't have that many signs...
