MoDOT I-270 Project announces two Dunn Road closures September 19 and September 21

Drivers who regularly use Dunn Road along I-270 should be aware that the Missouri Department of Transportation (MoDOT) will close the eastbound lane of Dunn Road from Hanley Road to Coldwater Creek at 5 a.m. September 19. This closure will be for 60 days. It will allow crews to begin replacing current highway entrance and exit ramps with new ones that will improve safety and reliability throughout the corridor.

MoDOT also will close eastbound Dunn Road between Washington Street/Elizabeth Avenue and New Halls Ferry Road beginning at 5 a.m. Wednesday, September 21. The closure will allow crews to continue converting Dunn Road to two-lane westbound only traffic. During the closure, one lane of westbound traffic will still be available to travelers.

Drivers should consider using alternate routes for both closures.

The closures are part of the ongoing infrastructure improvements being made on the $278 million I-270 North Project.
