Hi Andy
Seems a good idea. I would suggest a new tag, such as bridge_ref. 
I have come across cases of canal bridge numbers using the ref tag, which causes navigation instructions to be
continue onto A41
continue onto 107
continue onto A41

that one was near Tarporley.

Most canal bridge numbers are in the name tag, but I am not sure that is right either.

If we do not have something more specific, I'm happy to draft
something for discussion.
