The Illinois State Police have stepped up patrols and traffic enforcement along Interstate 57 near Mount Vernon, in Jefferson County in southern Illinois, in a work-zone safety push aimed at two major construction zones on one of the state's busiest north-south freight and travel corridors.

The increased enforcement began earlier this month, ahead of the busy holiday travel season. In the first week of November alone, troopers issued more than 650 citations and warnings, completed more than 80 commercial vehicle safety inspections and placed 17 commercial vehicles out of service for safety violations, the State Police said.

Three State Police units working together

Illinois State Police Director Brendan Kelly said the initiative brings together several divisions, including Troop 10 Patrol, the Commercial Vehicle Enforcement Bureau and the Special Operations Group. “To help ensure those traveling through the construction zones and those working in it are safe, ISP is increasing collaboration among numerous ISP work units,” Kelly said.

Troopers are focusing on the behaviours the agency identifies as the leading causes of crashes in construction zones: speeding, distracted driving, following too closely and failing to move over for stopped vehicles. A second Illinois outlet, Decatur Radio, reported the same first-week figures — more than 650 citations and warnings, over 80 motor carrier safety inspections and 17 commercial vehicles placed out of service — as the agency ramps up patrols for the holiday season.

Why this stretch of I-57 worries police

State Police reported that 50 percent of the crashes the agency handled in Jefferson County last year occurred inside a work zone. Interstate 57 runs the length of Illinois, from Chicago to the state's southern tip, and the Mount Vernon stretch carries heavy truck traffic between the Midwest and the South — which is why commercial vehicle inspectors are a central part of the operation, and why 17 trucks and other commercial vehicles were ordered off the road in a single week.

The Illinois Department of Transportation (IDOT) is working alongside the enforcement push to keep traffic moving. IDOT has maintained two lanes of traffic in each direction during peak daytime hours, scheduled some of the more disruptive construction activities during off-peak hours, reduced speed limits through the zones and installed additional lane markings.

Illinois Transportation Secretary Gia Biagi emphasised the workers behind the barricades. “In any work zone, the people working behind the cones and barricades want to get home safely to their families and loved ones,” Biagi said.

The fines drivers and truckers are facing

Authorities are reminding motorists that speeding in an Illinois construction zone carries significant penalties. A first offence carries a minimum fine of $250. A second offence brings a $750 fine and a 90-day driver's licence suspension. If a work-zone speeding violation injures another person, the driver's licence is suspended for a mandatory period ranging from six months to two years.

Illinois' Move Over Law also applies in full: drivers must slow down and move over when approaching qualifying stopped vehicles displaying emergency lights. A first violation carries a fine ranging from $250 to $10,000, and if the violation injures another person, the driver's licence will be revoked.

What happens next

Construction on the two Interstate 57 projects near Mount Vernon is expected to continue until June 2027 and October 2027, respectively, so the narrowed lanes are a long-term feature of this corridor, not a short disruption. The State Police say the increased enforcement will continue as holiday travel builds, and they are urging drivers to allow additional travel time, obey posted work-zone speed limits, keep a safe following distance and put distractions away.
