WEST DES MOINES, Iowa – March 30, 2026 – If you travel on eastbound Interstate 80 between Grand Prairie Parkway (Exit 118) and the I-80/I-35/I-235 Southwest Mixmaster need to be aware of upcoming nighttime road closures that may slow down your trip according to the Iowa Department of Transportation’s Creston construction office.

Crews will close eastbound I-80 nightly on the following nights from 8:30 p.m. until 5 a.m., weather permitting, so crews can install new hot-mix asphalt paving.

  • Monday, April 6 to Friday, April 10 from Jordan Creek Parkway (Exit 121) to the I-80/I-35/I-235 Southwest Mixmaster. When the roadway is closed, you will follow a marked detour route using Jordan Creek Parkway (Exit 121), University Avenue, and I-80/I-35 (Exit 124).
