SIOUX CITY, Iowa – Nov. 1, 2023 – If you travel on U.S. 30 west of Glidden you need to be aware of a construction project that may slow down your trip.

Beginning at 7 a.m. on Monday, Nov. 6, the Iowa Department of Transportation will close U.S. 30 west of Glidden in Carroll County for culvert replacement. 

U.S. 30 traffic will be detoured on Carroll County roads N-38, E-26, and N-41. The detour is expected to be in place until Nov. 12, weather permitting.

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.
