I'd say WA 9 in Snohomish on the grade separated portions would be an
expressway but where it's single carriageway and has intersections?
Not an expressway.  Major arterial but not quite a super-two.

I've also noticed this for parts of WA 26 and WA 17 in eastern Washington. Has anyone noticed this in other states or is this just something weird that Washington is doing?

Super 2 expressways are a thing though most places (like, say, Kansas)
commit to it completely if they're going to put in a super 2 and not
halfass it by only doing small parts of it.  The whole point of a
super 2 is that it's half the cost of a freeway.
