Last week was very eventful for the Iowa highway system. In addition to US 20 opening to four lanes, the long-desired, super controversial interchange along the Marshalltown diagonal opened.
That’s a reference to an exit that incorporates US 65, IA 117, IA 330, and County Road F17 into a single place (and means that, even before I got to Correctionville, my re-clinching of the state highway system would have to wait). The interchange, positioned between the former 65/117 and F17 intersections, required eminent domain on the Cleverley farm and that process received extensive news coverage. The DOT selected the interchange after considering a “J-turn” intersection.
