Nighttime road closures on I-80 at the I-35/I-80/I-235 east systems interchange in Polk County begin on Thursday night, Nov. 30

Des Moines, Iowa – Nov. 21, 2023 – If you drive near the Interstate 35/80/235 east systems interchange you need to be aware of an upcoming construction project that may slow down your trip.

Nighttime construction work to place bridge beams for the new bridge at the I-35/I-80/I-235 east systems interchange will require closing westbound I-80, the ramp from westbound I-80 to westbound I-235, and the loop from eastbound I-235 to westbound I-80 on Thursday, Nov. 30 from 11 p.m. to 5 a.m., weather permitting, according to the Iowa Department of Transportation’s Grimes Construction office. 

While work is taking place you will follow a marked detour route that will take you north to the Corporate Woods interchange and then back south to continue on westbound I-80 or westbound I-235 (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.
