IDOT Announces Full Closure on I-55 at I-80 Over Two Consecutive Nights

The Illinois Department of Transportation announced today that as part of ongoing efforts to rebuild the Interstate 80 bridges over Interstate 55 in Joliet, Channahon and Shorewood, a full closure will be required in both directions at I-55 at I-80 over two consecutive nights beginning, weather permitting, Monday, July 20. The closures are necessary to safely remove steel beams on the I-80 bridge over the expressway.

Monday, July 20

• Starting at 8 p.m., northbound and southbound I-55 will be reduced to one lane between Illinois 59 and U.S. 6.
• At 11 p.m., the eastbound I-80 ramp to northbound I-55 will close.
• Between midnight and 5 a.m., northbound I-55 will be fully closed at I-80.
• During that time, a detour will direct northbound I-55 traffic to exit at eastbound I-80 to northbound Houbolt Road and reenter westbound I-80 to access northbound I-55.
• One lane on northbound and southbound I-55 will reopen by 5 a.m., with all lanes and ramps open by 6 a.m. Tuesday.

Tuesday, July 21

• Starting at 8 p.m., northbound and southbound I-55 will be reduced to one lane between Illinois 59 and U.S. 6.
• Between midnight and 5 a.m., southbound I-55 will be fully closed at I-80.
• During that time, a detour will direct southbound I-55 traffic to exit at westbound I-80 to southbound Ridge Road and reenter that eastbound I-80 to access southbound I-55.
• All lanes and ramps will reopen by 6 a.m. Wednesday.

As the I-80 reconstruction continues, the public should continue to expect lane shifts, overnight lane closures and significant delays and allow extra time for trips through this area. Drivers are urged to pay close attention to flaggers and signs in the work zones, obey the posted speed limits and be on the alert for workers and equipment.
