FYI, I found, using taginfo, 5382 of bridge_ref but only 1612 of bridge:ref Even Though Wiki prefers the latter… bridge=*#The_building_number **I took on the western end of the Llangollen Canal as a bit of a challenge but did look at quite a few other UK canals for guidance on mapping. **I have now done Changeset: 53247341 to that area. **Please do let me know if you have any further comments on my work - as we can’t all be right all the time!
