CRESTON, Iowa – June 30, 2021 – An interchange project 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, according to the Iowa Department of Transportation’s Creston construction office.

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.
