The Illinois Department of Transportation announced a complete weekend closure of northbound/eastbound lanes of Interstate 55/70 between Illinois 159 and I-270, beginning at 6 p.m. Friday, Aug. 6, weather permitting.
This northbound/eastbound section will be completely closed to traffic for the weekend. It will be reopened to traffic at 6 am, Monday, August 9. The stretch runs from near Maryville to Troy.
The detour route for this closure is as follows:
From I-55/70 northbound/eastbound to I-255 northbound to I-270 eastbound to I-55 northbound or I-70 eastbound.
The southbound/westbound direction of I-55/70 will remain open.
This stage of work is necessary to build a new asphalt surface and is expected to be completed by Aug. 9. It’s part of a larger project that will include many additional lane closures. The times and locations of future closures will be announced as the project continues. The entire project is expected to be completed by November.
Drivers may experience delays when traveling on alternate routes in this area during the closure. Drivers are urged to reduce speed, be alert for changing conditions, obey all construction signage, and refrain from using mobile devices while approaching and traveling through the closure area.
