GRIMES, Iowa – October 8, 2025 – If you drive on Towner Drive west of Iowa 141, you need to be aware of a permanent closure that may affect your travel plans, according to the Iowa Department of Transportation’s Grimes Construction office.
As part of our changes to the Iowa 141 corridor to improve safety, crews will be terminating the Towner Drive access on the west side of Iowa 141. The closure will go into effect on Monday, October 13th. The contractor is also working to remove several median crossovers and regrade ditches in the area.

When Towner Drive is closed, you will need to use NW 121st Street to get access to Iowa 141.
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.
