Traffic pattern changes on U.S. 18 and Iowa 51 in Postville begin on Monday, April 1

NEW HAMPTON, Iowa – March 19, 2024 – If you drive on U.S. 18 and Iowa 51 in Postville you need to be aware of an upcoming asphalt paving and resurfacing project that may impact your trip.

Beginning on Monday, April 1, until mid-November, weather permitting, crews will need to shift traffic in a head-to-head traffic pattern on one side of the road in some sections of the work zone.

Flaggers will assist you through the work area when paving and related work is underway.

Part of this project includes updating sidewalks to be compliant with the Americans with Disabilities Act. To get this work done, we’ll need to close some of the side roads in the area from time to time.

Help keep everyone on the road safer. 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, you should stay alert, allow ample space between vehicles, and wear seat belts.
