From the MoDot website: "expressway - a multi-lane, typically four or more, highway with limited controlled access; access points may consist of intersections or interchanges"

The term expressway in Missouri parlance is exactly what both Chestnut and Kansas are. Missouri expressways. Full access control is called a freeway. John Q. was instrumental in directing I-44 to the north side instead of through town, where Chestnut is now, in the 1950s. Good or bad it was debated then. And freeways through the hearts of cities decimate neighborhoods, usually poor and lacking political power.

I got banned for reacting with an angry face. That's it.
