Full closure of westbound I-80 at 1st Avenue (exit 242) in Coralville on Thursday night, June 15

DAVENPORT, Iowa – June 9, 2023 – If you drive on westbound Interstate 80 in Coralville you need to be aware of a construction project for the new I-80 and 1st Avenue interchange that may slow down your trip.

Construction crews need to fully close westbound I-80 at the 1st Avenue interchange (exit 242) from 11 p.m. Thursday, June 15 until 5 a.m. Friday, June 16, weather permitting. Drivers will be detoured off I-80 at the 1st Avenue ramp (exit 242) and follow a marked detour to the entrance ramp for westbound I-80 (see map).

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.
