So, the thing is, I think most mappers are quite used to there being a level between motorway and trunk for all the weird expressway (and superstroad) type things like this, given that highway=trunk historically has meant expressway=yes in the US.  I also think the sample size of who was consulted was likely too small if this is a situation that keeps happening.

I detected hostility because Elliott came into the thread hot and immediately flashes a badge at someone who's been working on OSM just as long and far more prolifically.

I have actually been up and down OKC Boulevard a few times; I do see the whole length as a single classification because it's pretty obvious that's what the intent was.  If it wasn't OKC's intent, they shouldn't have signed off on that; they had the option of just having the freeway removed instead of converted to an expressway.

I did read the proposed classification above. I can't honestly see another classification that fits, given all but the middle couple blocks with the hotel and on-street parking are the only part that isn't full blown expressway.  I am open to other suggestions, though not ones that involve classifying it as a motorway in any part.  Expressways can and do regularly have grade separated intersections, too, and calling the western few blocks a motorway for it seems like troll tagging now that there's apparently an effort to obfuscate weird expressways from the map.
