Dunn Road will see closures starting Monday for I-270 North Project

Drivers should consider using alternate routes starting next week.

ST. LOUIS — The Missouri Department of Transportation announced two road closures on Dunn Road starting Monday, Sept. 19. The closures are part of the $278 million Interstate 270 North Project, which aims to reduce traffic congestion on the interstate as well as its interchanges and outer roads.

Starting 7 a.m. Monday, the eastbound lane of Dunn Road will be closed from Hanley Road/Graham Road to Coldwater Creek. Drivers will still have access to the I-270 westbound entrance ramp.

The closure will allow crews to begin replacing the highway entrance and exit ramps. The new ramps will help improve safety and reliability.

MoDOT expects this closure to last 60 days.

At 7 a.m. Wednesday, Sept. 21, MoDOT will close eastbound Dunn Road between Washington Street/Elizabeth Avenue and New Halls Ferry Road.

This will allow crews to convert Dunn Road to multi-lane, westbound-only traffic. During the closure, one westbound lane on the road will still be open for travelers.

The department recommended that drivers should consider using alternate routes during the closures.
