If that were the case, then we'd have lots of partially controlled access routes (i.e. no driveways, but at-grade intersections) to change to "primary." IMHO, routes with partial control of access should be classified as "trunk" and any highway with fully controlled access (all cross roads are grade separated) should be classified as "motorway," including those routes that are not quite to interstate standards.

I *strongly* dispute Paul's assertion that a highway that has fully controlled access but is single carriageway should be "trunk" instead of "motorway." Access control, not number of lanes, should be the primary guidance behind a motorway or trunk classification. _______________________________________________ Talk-us mailing list [email protected] https://lists.openstreetmap.org/listinfo/talk-us
