[Talk-us] Fwd: Trunk versus motorway

I always tag based on the actual access control. At the end of a clear
freeway, continue the motorway tagging to the first intersection or
driveway, or if the road becomes single-carriageway and isn't a super-2 (a
controlled-access freeway in which only one carriageway is constructed with
accommodation for the second later). There is no "except for the

If a road like that has enough intersections spaced throughout its length,
it should be tagged as trunk, perhaps with expressway=yes. Though with just
two or three intersections nearby in the middle of a freeway (for example
the handful of remaining intersections in the mostly-freeway section of US
29 in Maryland), I'd tag it as trunk only between the intersections and
make the rest motorway.

The Tisdale Parkway should absolutely be tagged as motorway starting from
the Gilcrease intersection southward. Gilcrease should be motorway as well
from where it becomes dual-carriageway. The remaining sections of each of
these roads should be tagged as trunk.
