March 8, 2023 — For immediate release

St. Louis —Drivers who regularly use Dunn Road should be aware of an upcoming closure near Lynn Haven Lane. The Missouri Department of Transportation (MoDOT) will close both eastbound and westbound Dunn Road in that area in both directions for four weeks, beginning 7 a.m., Monday, March 27. The closures will allow crews to reconfigure Dunn Road to run continuously from Hanley Avenue to McDonnell Boulevard, creating the final connection from Dunn Road to Southbound Lindbergh Boulevard.

"These upgrades will allow those who wish to travel Dunn Road west to drive all of the way to McDonnell Boulevard, without needing to access Taylor Avenue," said Eric Kopinski, I-270 North Project Director.

During the closures, those traveling east on Dunn Road will need to travel Lynn Haven Lane to Imperial Drive, and then south to Dunn Road, where they can continue on Taylor Avenue or connect to either northbound or southbound Lindbergh Boulevard. Those wanting to travel west on Dunn Road, will need to travel Lynn Haven Lane to Imperial Drive, and then south to Dunn Road. Access to Village Square will be available via Lynn Haven Lane.

The closures and construction work are part of the $278 million I-270 North Project infrastructure upgrades.
