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.

See http://www.openstreetmap.org/browse/relation/446579 as an example. I don't know if this a good idea or not, nor if the number is what you have in mind.

I have looked on Wiki, and can't find anything, and my local bridges are either not tagged; or tagged (for example) ref = B4124: http://www.openstreetmap.org/browse/way/103233329 which does not identify that number as being a NetworkRail reference (if indeed it is, being on a road overbridge maintained by the local authority). If we do not have something more specific, I'm happy to draft something for discussion. -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
