Areas don't have a direction :).

To show that a way travels over a particular paved section of road, the geometry should be adequate. On the other hand, to show that these paved areas, plus these sidewalks, plus these center-islands, plus these ways, etc., make up "Dale Mabry Highway", sounds like a job for a relation. > Apologies if this has been discussed before - if it has, please point > me to the relevant discussion page :) > It has been discussed ad-nauseum in some form or another as long as I've been reading this mailing list.
