Project Status Update, 03/12/2026:

Please check the Iowa DOT links ABOVE for the latest information from the DOT. This is a DOT-led project, and this City webpage may not have their latest information. The Iowa DOT will post detours and message boards for all closures.

• 3/12/26 from the Iowa DOT: Our construction crew needs to reconfigure the northbound I-35/eastbound I-80 lanes of traffic by shifting the travel lanes to the east. Work will be taking place in the middle of the interstate this year; the work includes reconstructing the pavement and replacing the existing bridge in the center of U.S. 6/Hickman Road. The following closures are planned to implement the new traffic shift:
  • Northbound I-35/Eastbound I-80 will be closed to traffic March 16 - 20 from 10 p.m. – 4 a.m. Backup dates if weather is an issue will be the following week, March 22 - 27.
  • The ramps at University Avenue and U.S. 6/Hickman Road will also be opened to traffic once the shift has been made.

Upcoming overnight closures – Please see links ABOVE for the latest information.  When I-80/I-35 is closed, you will typically follow a marked detour route that uses I-235, 100th Street, NW Urbandale Drive, and I-80/I-35.

Trail closures in the Clive Greenbelt began last fall.  Detours are posted for bicyclists and pedestrians.
