Overnight closures on Interstate 80 in Des Moines are continuing, disrupting both westbound and eastbound traffic as grading and concrete work proceeds on the highway. The closures are significant for residents who rely on I‑80 for daily commutes, deliveries and regional travel.

Westbound I‑80 between the Southwest Mixmaster and Grand Prairie Parkway is shut down each night beginning at 8:30 p.m. and remains closed until 5 a.m. The nightly closure will repeat through Friday, Nov. 13. Drivers traveling west are directed to use University Avenue and Grand Prairie Parkway as a detour; the detour route is highlighted in green on the map provided by KCCI.

Eastbound I‑80 is also affected. The lane between the East Mixmaster and Exit 141 is closed overnight. It will reopen at 5 a.m. on Monday, but the closure will continue each night until Thursday. The same detour options—University Avenue and Grand Prairie Parkway—are recommended for eastbound travelers.

The repeated overnight shutdowns mean that motorists should anticipate longer travel times during the evening and early‑morning hours. Residents are encouraged to plan alternate routes, allow extra time for trips that cross the affected sections, and stay alert for posted signage indicating the detour pathways.

Local officials have not indicated any change to the schedule, and the construction work is expected to proceed as planned. The grading and concrete work is part of a broader effort to improve the highway’s surface and structural integrity, which will ultimately benefit Des Moines drivers once completed.

What’s next: The westbound closure is set to end on Friday, Nov. 13, while the eastbound shutdown will cease after Thursday. Motorists should monitor local traffic reports for any updates and continue to use the recommended detour routes until the work is finished.
