St. Louis Work Zones September 15-21

ST. LOUIS – Drivers who regularly use Dunn Road along I-270 in North St. Louis County should consider using alternate routes as eastbound Dunn Road from Hanley Road to Interstate 170 will close beginning at 5 a.m. September 19. This closure will last 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.
