For St. Louis commuters, the upcoming week is shaping up to be a confluence of lane closures and detours. The Missouri Department of Transportation (MoDOT) has announced a series of work zones that will impact travel on several major roadways, with closures starting today and running through Wednesday. Among the most impactful, eastbound Reavis Barracks is facing a lane closure around the I-55 interchange beginning at 7 a.m. on Monday, with the restriction expected to last two weeks.

According to MoDOT's advisory, the lane closure under I-55 is for drainage updates that will continue uninterrupted, unless weather conditions dictate otherwise. While all interstate ramps will still be accessible, MoDOT warns that backups are likely, particularly when heading towards Union Road. With one southbound lane of I-55 also closed from I-44 to north of Bates and multiple other ongoing closures across the city, travelers can anticipate a testing period on St. Louis roadways.

Updates on real-time roadway weather conditions can be accessed at MoDOT's traveler map, while traffic updates are available through the Gateway Guide. Commuters are advised to check these resources before heading out. Crews will be actively working on several other significant routes, including lane narrowings on I-270, closures on Route 67, and full ramp closures in multiple areas across the city and county, all with varying schedules.

For a full picture of daily closures and work schedules, MoDOT advises drivers to stay informed via their website. They urge public cooperation and patience as crews work diligently to complete the projects as swiftly and safely as possible. Commuters are encouraged to plan for extra travel time or seek alternative routes where feasible to minimize frustration during these construction efforts.
