The relation's scope goes beyond parallel dual-carriage ways. Suppose there's a parking on top of the bridge, or any other type of building, amenity, service... You'd include it in the relation, thus indicating it's on the bridge. There's no way to do it without the realtion. > Richard Simone _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
