Traffic shift on U.S. 218 and Iowa 57 in Black Hawk County scheduled to begin on Monday, Sept. 18

NEW HAMPTON, Iowa – Sept. 11, 2023 – Continuing work on U.S. 218 and Iowa 57 in Black Hawk County will impact the lanes you use beginning Monday, Sept. 18, weather permitting. On that day you’ll be shifted to the outside two lanes of the road. All current closures and detours will remain as we continue to work on this portion of the highway.

A mobile message sign will be in place to alert you about the upcoming traffic switch. The work on this phase of the project is expected to be completed by mid-November.

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.
