Lane changes and ramp closures along Interstate 80 on Joliet and New Lenox began on Monday as construction workers prepare for improvements to the roads.
Long-term ramp closures include the southbound Interstates 55 to eastbound I-80 ramp, which is expected to reopen in fall 2026 and the northbound I-55 to westbound I-80 ramp, which is expected to reopen this fall, according to the Illinois Department of Transportation.
Starting Tuesday, eastbound I-80 will be reduced to one lane from 8 p.m. to 5 a.m. from River Road east of I-55. Two lanes will be open to traffic by 5 a.m. Wednesday. Traffic will shift to the right and both shoulders will be closed, according to IDOT.
Westbound I-80 will be reduced to one lane from 8 p.m. to 6 a.m. from Houbolt Road to River Road, and two lanes will be reopened by 6 a.m. Friday. Traffic will shift to the right and both shoulders will be closed, according to IDOT.
The lane closures, according to the Monday news release, are to install a new traffic pattern and work zone on I-80. Drivers should expect lane shifts, overnight lane closures and significant delays.
