Map users expect to see expressways shown differently.
Could you show me an example of a US road atlas that explicitly demarcates expressways? I have legitimately tried to find one but have not been able to. Most US maps I've seen show freeways & toll roads explicitly, but not expressways. Some maps might use a different casing style to denote a divided highway, but the underlying color of the line still represents the importance of the road. Which is the point I'm trying to get at, that a highway being divided or not is orthogonal to its importance. > It's less work on so many levels also.

The wiki definition for primary is already "the > most important non-motorway route between two cities" (essentially, and > ignoring the variation in use between rural and urban areas) This is incorrect. 'Tag:highway=primary' gives "A highway linking large towns". 'Tag:highway=trunk' gives "Important roads that are not motorways", and explicitly lists in the US tagging application that "a major intercity highway" is a correct use of the trunk tag in the US. 'Highway:international_equivalence' as well as 'Key:highway' give the same set of definitions. Where are you seeing that primary is "the most important non-motorway route between two cities"? _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
