Lane closures on Iowa 175 in Onawa begin on Monday, April 3 

SIOUX CITY, Iowa – March 27, 2023 – Drivers on Iowa 175 in Onawa need to be aware of a construction project that may slow down their trip. Beginning at 8 a.m. on Monday, April 3 until Oct. 1, weather permitting, traffic will be reduced to one lane in each direction as crews work to replace the Iowa 175 bridge over McCandless Cleghorn Ditch.

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.
