Where a wall has been built so it spans a stream (say with a lintel above the waterline), should that be marked? So far I've put:

  • a. layer=1,

But I don't know if that's unnecessary and I should just

  • b. do nothing, just leave them crossing,

or tag it specifically

  • c. layer=1, bridge=yes

The bridge documentation doesn't make it clear if it would be appropriate to combine it with a wall. Thanks

If two objects are crossing at different levels you should always make that clear using the layer tag (not level which is used for floor levels in buildings). The layer of the wall needs to be higher than the layer of the stream.

Also make sure the lines are not connected, i.e. there is no common node.

For such small object like a wall or fence I would not bother with tagging a bridge or a culvert (tunnel).

Thanks. You're totally right, I meant layer and fortunately that's what I've used so far. I'll edit my question.
