CRESTON, Iowa – June 30, 2021 – The Iowa DOT’s Creston Construction Office reports an interchange project in Dallas County intended to improve traffic flow during peak hours at the Interstate 80/U.S. 169 interchange (exit 110) will require lane and shoulders closures and an eastbound off ramp and westbound on ramp detour beginning at 8 a.m. Tuesday, July 6, until Tuesday, November 16, weather permitting.

Work on this project includes pavement widening to add turn lanes on U.S. 169 and the on- and off ramps at the I-80/U.S. 169 interchange, pavement resurfacing, and adding traffic signals at the interchange. Ramps on the west side of the interchange may be closed for a short period of time. During these closures, marked detour routes will be in place.

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.
