Could you show me an example of a US road atlas that explicitly<br>
demarcates expressways? I have legitimately tried to find one but have<br>
not been able to. Most US maps I've seen show freeways & toll roads<br>
explicitly, but not expressways. Some maps might use a different<br>
casing style to denote a divided highway, but the underlying color of<br>
the line still represents the importance of the road. Which is the<br>
point I'm trying to get at, that a highway being divided or not is<br>
orthogonal to its importance.<br>

<br>
This is incorrect. 'Tag:highway=primary' gives "A highway linking<br>
large towns". 'Tag:highway=trunk' gives "Important roads that are not<br>
motorways", and explicitly lists in the US tagging application that "a<br>
major intercity highway" is a correct use of the trunk tag in the US.<br>
'Highway:international_<wbr>equivalence' as well as 'Key:highway' give the<br>
same set of definitions. Where are you seeing that primary is "the<br>
most important non-motorway route between two cities"?<br>
