Yes. Because for the majority of that length that isn't between US 20 and
County Road 40 is, for all practical purposes, the same generic two lane,
shoulderless ribbon of pavement that pretty much any two lane Texas FM or
RM road, or pretty much any other similar road in the American west.
Primary is more than ample for such a road.

Or, map it cleanly to limited access expressways and super2s. I really
think people are trying to overthink this a bit; being a little less
subjective isn't necessarily a bad thing.
