Yes, this is what I do. In fact the example which Chris picked out was done by me a few years ago when I cycled through the area. I’ve tagged quite a few bridges like this in Kent. You’ll also notice that I’ve included the operator, operator’s phone number, bridge name, etc. on the relation too when they’re included on the sign.


Railway structure numbers seem to have a letter portion, which denotes the line, and a sequential numeric portion. Occasionally there are places where an extra bridge has been added and these have a letter suffix, just like extra motorway junctions.

Some railway bridges near me have already been added to a bridge relation, not by me, that includes the reference. 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.

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