Des Moines, Iowa – Nov. 29, 2023 – The Iowa Department of Transportation reports if you drive near the Interstate 35/80/235 east systems interchange, you need to be aware of upcoming construction work 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 the following areas overnight on Tuesday, Dec. 5 and again on Wednesday, Dec. 6. The closures are expected to begin at 10 p.m. and run through 5 a.m. the next morning.

• All lanes of westbound I-80
• The ramp from westbound I-80 to westbound I-235
• The loop from eastbound I-235 to westbound I-80

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 cautiously, 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.
