Iroquois County, IL – Drivers traveling through Iroquois County should plan for overnight delays beginning Tuesday night as crews close a section of Interstate 57 near the Illinois 54 interchange for bridge construction work.
According to the Illinois Department of Transportation (IDOT), I-57 will be fully closed at the Illinois 54 interchange from 6 p.m. to 6 a.m. for three consecutive nights, starting Tuesday, December 16, weather permitting. The overnight closures are necessary so crews can safely demolish portions of the Illinois 54 bridge deck that crosses over the interstate.
During the closures, traffic on I-57 will be detoured using the Illinois 54 exit ramps. Illinois 54 itself will remain open, but only one lane in each direction will be available as flaggers manage traffic through the work zone.
IDOT officials warn motorists to expect delays, especially during evening and early morning hours, and urge drivers to consider alternate routes when possible. Reduced speeds and changing traffic patterns are expected throughout the construction period.
The work is part of a $5 million infrastructure project aimed at replacing the Illinois 54 bridge deck. The full project is expected to continue into late 2026, though the overnight closures announced this week are limited to the current demolition phase.
Drivers are reminded to slow down, obey posted signage, and remain alert for construction workers and equipment in the area.
