Road construction work on Iowa 78 between Penn Avenue and Quaker Avenue near Winfield will require closing the road to traffic beginning this Wednesday, July 18, weather permitting, according to the Iowa Department of Transportation’s Mount Pleasant construction office. The closure had to be postponed earlier due to wet conditions.

Once the project is in place, motorists will be directed around the work zone using a signed detour route.

  • Motorists traveling east on Iowa 78 will be detoured by traveling south on Oasis Avenue for 2 miles, east on Henry County Road H-28 for 2.5 miles, and then north on Henry County Road X-23 for 2 miles to reach the junction with Iowa 78

The Iowa DOT reminds motorists to 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, drivers should stay alert, allow ample space between vehicles, and wear seat belts.
