TROY – The Illinois Department of Transportation (IDOT) announced a complete weekend closure of northbound/eastbound lanes of I-55/70 between IL 159 and I-270, beginning on Friday, August 6, 2021 at 6:00 pm, weather permitting. This northbound/eastbound section of roadway will be completely closed to traffic for the weekend. It will be reopened to traffic at 6:00 am, Monday, August 9. 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.
