Not all Interstates *ought* to be tagged as motorways. A case in point is Interstate 93 in Franconia Notch, New Hampshire, which *ought* to be a trunk (it's a two-lane road with a centre guard rail that was added long after the initial construction.) Many motorways are not Interstates. The local law where I live doesn't special-case Interstates, but rather uses phrasing like 'multi-lane grade-separated controlled-access highways'. But that said, if a piece of legislation says, 'Interstate', then it means specifically 'Interstate', whether motorway or not, and not other motorways. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
