The flyover ramp from northbound I-35/80 to IA 141 in Urbandale should be open by the end of this month, KCCI reported recently. (Like too many TV stations nowadays, unfortunately, I am unable to embed the video.) Lanes will be added to 141 too, but no intersections will be closed between I-35/80 and IA 44.
The interchange area is known as the Rider Corner but has been subjected to a rebranding effort whose main achievement appears to be no one remembers how to spell “Rider”. The plans were finalized in October 2016.
The project overall includes a half-exit to Meredith Drive (northbound off, southbound on). The 100th Street exit opened in October 2018. That will result in 3½ interchanges between Douglas Avenue and Merle Hay Road when the late-1950s construction had only one (IA 141).
