The right lane of northbound Interstate 55 just south of Arsenal Road was closed Wednesday to perform emergency pavement repairs.
The repair is anticipated to be completed and the lane reopened by 5 a.m. Thursday, the Illinois Department of Transportation said in a news release.
"Long travel delays can be expected on northbound I-55 between Route 113 and Arsenal Road," the release said. "As an alternate route, traffic on northbound I-55 can exit to northbound Route 47 in Dwight to reconnect with I-55 via eastbound Interstate 80."
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.
