I don't think any part of it is a motorway anymore (again, expressways have ramps, too), but I do think all but the middle 3 stroad blocks are an expressway.  It's basically Salem Parkway except unlike Salem Parkway, it never actually steps down into fitting its surroundings and integrating with its surroundings functionally any better than the freeway did.

Most of us are in agreement that this isn't a motorway.  Also don't think it really does justice or brings anything useful or informative to the table to switch the highway=* value in the middle; all they did was take a freeway, remove most of the grade separation, and expect it to work better than Northwest Expressway does at being a surface street somehow.

It's also rather difficult to classify because I think most people would clearly consider EK Gaylord a more major street in terms of importants, possibly even Walker Ave, but highway=tertiary, expressway=yes also feels weird.
