Proposal

Canal bridges, and some other bridge types too (railway bridges, certainly) have bridge numbers for navigation or for quick unambiguous reference. Example: a local railway bridge has a sign on it saying "In case of bridge strike, call 0800 ?????? and quote bridge number N12345". Canal boaters use bridge numbers as a primary means of navigation and direction. We need a tag to encode this. Because a bridge may be given a reference by both the thing passing over and the thing passing under it, we have two tags - over_ref and under_ref.

Tagging

over_ref=ref
under_ref=ref

Both over_ref and under_ref are placed on the way which has "bridge=yes" (or whatever the correct bridge tagging is), i.e. the "over" way.

Rendering

  • I disapprove this proposal. It's complicated but still doesn't work in a all cases - e.g. what about two bridges above each other. Either a simple approach that works in 90% or a complicated that really works in all cases. -- Ulfl 01:52, 7 March 2008 (UTC) - Ulfl 11:05, 21 March 2008 (UTC)
  • Ulfl: What do you mean by "two bridges above each other"? Can you provide an example on OSM? Can you suggest a scheme which incorporates these cases? -- Gerv 08:19, 8 March 2008 (UTC)
  • Well, the ground, a bridge over the ground and a second bridge over the first one. No. No. - Ulfl 03:07, 20 March 2008 (UTC)
