21518	Paint expressway=yes (similar to motorroad=yes)	adamfranco	team	"The [https://wiki.openstreetmap.org/wiki/Key:motorroad motorroad] concept doesn't map cleanly to the legal situation in the US, so mappers in the US have been standardizing on the [https://wiki.openstreetmap.org/wiki/Key:expressway expressway] key to designate high-throughput roads that do not meet the motorway criteria. Conceptually, motorroad is about access control first and foremost and the roads it applies to often have enhanced physical infrastructure. In contrast, the expressway=yes concept starts with the physical properties (multiple lanes, grade separation, higher speed designs) and these roads often (but not always for their full length) have some level of access restrictions which may or may not be equivalent to those for motorroads. The roads in question are often very similar, but the two tags approach a related concept from opposite reasoning.

Using the same or similar painting style would be useful for those mapping in the US to more easily distinguish between trunk/primary/secondary/¿tertiary? roads that are tagged as expressways and those segments that aren't tagged with expressway=yes. These concepts may be considered close enough to use the same rendering in JOSM. In fact, [https://github.com/openmaptiles/openmaptiles/issues/1148 issue #1148] in the OpenMapTiles project intends to surface them both as equivalents for renderer styles using OpenMapTiles.
