The Missouri Department of Transportation (MoDOT) announced it will be shutting down one lane of the southbound I-170 entrance ramp from westbound I-270. Starting Friday at 8 p.m., commuters will need to find alternate routes or allow for extra travel time until the lane reopens on Monday at 6 a.m. MoDOT advises motorists that traffic may be impacted.

The closure will allow maintenance work on a busy stretch of road known for heavy traffic, especially during peak hours. MoDOT says the work is intended to improve safety and traffic flow.

Drivers can check MoDOT’s website or mobile app for updates and detour routes. While details of the maintenance have not been released, the closure is expected to last through the weekend and be completed before Monday’s commuter traffic. Motorists are advised to plan ahead and use caution around construction crews.
