Iowa 333 near Hamburg to close on Monday, April 1

COUNCIL BLUFFS, Iowa – March 15, 2024 – If you drive on Iowa 333 near Hamburg you need to be aware of an upcoming road closure that could impact your trip.

Beginning on Monday, April 1, weather permitting, crews will close the roadway from the BNSF Railroad to 0.6 miles east of Interstate 29 so grading and paving work can be done, according to the Council Bluffs construction office. This work will aid in flood protection and raise the grade of Iowa 333 as pavement is replaced. While Iowa 333 is closed you will follow a marked detour route using I-29, Iowa 2, U.S. 275, and Iowa 333.

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.
