O’FALLON, IL – Drivers across the Metro East are facing significant delays today after a serious crash shut down lanes on Interstate 64 eastbound near the US-50 interchange in O’Fallon. Traffic is currently moving through the crash site, but only slowly, with backups expected to continue through the morning commute.
According to the Illinois State Police, troopers are on scene at milepost 14 handling what they described as a “serious crash” affecting eastbound travel. Officials did not immediately release details on injuries or the number of vehicles involved, but emphasized that the crash is causing major slowdowns for anyone traveling toward Nashville, Mt. Vernon, or southern Illinois.
State police said traffic is “getting by slowly,” and the agency is urging drivers to SLOW DOWN and MOVE OVER when approaching the crash area. Troopers are currently managing lane closures and working to clear the roadway.
The slowdown is impacting drivers throughout O’Fallon, Shiloh, Fairview Heights, and other parts of St. Clair County, with congestion extending several miles west of the US-50 exit. Commuters heading from the St. Louis metro toward eastern Illinois should expect extended travel times and consider alternate routes, including using IL-161 or US-50 to bypass the area.
No estimated time for full lane reopening has been provided. State police are expected to release additional information as the investigation continues and crews remove debris from the roadway.
Drivers in the Metro East are encouraged to monitor traffic apps and allow extra time throughout the morning.
