Where there is a physical barrier, splitting a road in two, tag as two separate ways, with a oneway tag. Where a physical barrier splits a road in two, this is a dual carriageway, regardless of how many lanes each carriageway has. It doesn't matter if a dual carriageway has at-grade junctions (i.e. just gaps in the barrier or side-turnings), or motorway-style slip-roads and bridges - they are still both dual carriageways and must be tagged with two ways. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
