Nevermind. Yes you can. If the center of the 3 lane road is to the left of the center of the 2 lane road, then the lane was added on the left. If the center of the 3 lane road is to the right of the center of the 2 lane road, then the lane was added on the right. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
