In that case, that bridge can have differen speed limits set directly on the way. Just define that tags on individual ways override tags set in the zone and this will solve the issue. > So while it may work for many zonal restrictions to use an area > (although even then there are still issues) you need another way as > well due to the bridge/tunnel issue, and that other mehod can only be > relations. I've seen many zones with some limitations (mostly speed limit or some parking limitations), but such zones rarely contain any bridges or tunnels. If they do, they can be either tagged individually, or we can also make new relation that will contain the zone and roads that are NOT in the zone (relation containing those few exceptions like the bridges, tunnels, etc ... so they won't need individual tagging) Martin _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
