Des Moines Roads: Major Interchange Updates | Des Moines News

Roads around Des Moines are transforming fast—here’s what’s coming next: Hickman Road interchange gets a diverging diamond with partial closures starting September 2026, and full bridge work in spring 2027. The Northeast Mixmaster, nearly done after 20 years, will finish with new lanes and medians by 2027. I-35 expansion from Ankeny to Huxley wraps by winter, then immediately kicks off northward to Ames.
