Northbound I-55 lane closures

CHICAGO – The Illinois Department of Transportation announced today that as part of ongoing efforts to rebuild Interstate 80 in Minooka, Joliet and New Lenox, a lane closure will be required on northbound Interstate 55 near I-80. The closure is necessary to accommodate replacement of the I-55 ramps to eastbound I-80. ​

To safely establish the work zone, starting at 8 p.m. Wednesday, Feb. 5, overnight lane closures are scheduled to take place on the northbound lanes of I-55, between U.S. 6 and I-80. At least one northbound lane will remain open and southbound I-55 will not be impacted. Additionally, starting at 1 a.m., the northbound I-55 ramp to eastbound I-80 will close. During that time, a detour will direct motorists to exit I-80 (westbound) and reenter I-55 (southbound) to eastbound I-80.

The ramp and lanes that were closed overnight will reopen by 5 a.m. Thursday, when the new traffic pattern will be in place. In the new configuration, northbound I-55 will be reduced from three to two lanes from north of U.S. 6 to I-80 (approximately one mile), the right shoulder also will be closed. ​

As the I-80 reconstruction continues, the public should continue to expect lane shifts, overnight lane closures and significant delays and to 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.
