We're not supposed to map for the renderer nor the router.

Sounds like you're the official spokesperson for OSM, are you? The convention you're referring to simply states "(physically) Divided highways should be drawn as separate ways." It doesn't say anything about legally divided highways, that is left out. Currently mappers treat legally divided highways in different ways. I'm definitely not the only one to map them as two ways. Also, no one has offered any other solution to the routing issue. The divider tag has been proposed, but I think it has been demonstrated not to work, as routing decision are made on the node and not on the line. /Markus _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
