Madison County, Illinois – Lane closures begin tonight on I-270 in Madison County, reducing traffic to one lane each direction.
According to the Illinois Department of Transportation, closures start at 9 p.m. Friday, Feb. 20, affecting both eastbound and westbound I-270 between Illinois Route 3 and Riverview Drive in Missouri.
IDOT said the restrictions are required for roadway repairs. One lane will remain open in each direction throughout the work zone.
All lanes are expected to reopen by 5 a.m. Monday, Feb. 23, according to the department.
The affected stretch of I-270 connects Illinois drivers to key Missouri routes near the Mississippi River crossing and the St. Louis metro area. The overnight and weekend lane reductions could slow traffic, particularly for commuters and students traveling across state lines.
Motorists are advised to allow extra time, reduce speeds in the work zone, and watch for posted signage.
IDOT has not announced additional closures beyond Monday morning but encourages drivers to monitor official updates.
