There's a lot of one-lane-each-way primaries in the US. And thanks to some continent-wide data torquing by NE2, a lot of one-lane-each-way trunks. The former's a fact of life, America has a lot of extremely rural primaries running through badlands, mountain peaks or otherwise just don't require extra capacity despite connecting cities. The latter probably needs to be solved with a ban. _______________________________________________ Routing mailing list [email protected] http://lists.openstreetmap.org/listinfo/routing
