OK, I can accept it if layers are "essential" , but I have noticed that any
of the bridges over waterways I have edited seem to render OK. (But I'll
change them when I happen to come across them again.)

If layer tags are essential, wouldn't it be helpful to have the 'layer' tag
automatically included (appear) when a 'bridge' or 'tunnel' tag is selected
in the editor of choice? Just a thought.

Also, does adding a bridge section with a layer of 1 mean I should also tag
the surface road with a layer of 0 or is the default no tag (layer 0) good
enough?

Sorry to be nit-picky, but I just want to make things clearer for us
newbies.

Thanks for the comments

Robert
