MARSHALLTOWN, Iowa – Aug. 26, 2025 – The westbound I-80 entrance ramp at the U.S. 63 interchange (exit 191) will be closing on Tuesday, Sept. 2, through October for reconstruction work.
When the interchange is closed, you will be detoured around the work zone and travel on I-80 and Poweshiek County Road V-18.
Changes could made to detour routes during the construction season. Please visit 511ia.org for current detour route information before traveling through this construction zone and pay attention to detour signing and messages boards while driving.
The Iowa DOT reminds motorists to drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
