I'm fine with that if we can be consistent. But that means http://g.co/maps/4j2uh is tagged as lanes=0, lanes:turning:left=2, lanes:turning:right=2. It might be safer to to use lanes:through=X if you only want to include through lanes. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
