SIOUX CITY, Iowa – March 26, 2024 – If you drive on Iowa 39 from Odebolt south to Denison you need to be aware of an upcoming construction project that may impact your trip.

Beginning at 9 a.m. on Wednesday, March 27, until late April, weather permitting, the road will be closed as crews work to improve the surface of the road, according to the Iowa DOT District 3 Office. You will be directed to a marked detour route while the roadway is closed.

While the road is closed, you will still be able to get to local homes and businesses.

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.
