The Illinois Tollway announced on March 30 that lane reductions and traffic shifts will begin next week at the Arlington Heights Road and Barrington Road interchanges on the Jane Addams Memorial Tollway (I-90). The changes are part of ongoing toll plaza canopy removal and improvements, with work expected to continue into 2027.
These upgrades are intended to improve traffic flow and operations at the interchanges. Electronic message signs and construction signage will be installed in advance to alert drivers about upcoming closures. Up-to-date information will be posted in the Daily Construction Alert section of the Tollway website. All scheduled work is weather dependent.
According to the Illinois Tollway, extended lane reductions and traffic shifts will last through the end of this year at Arlington Heights Road Interchange, while similar measures at Barrington Road Interchange are set to continue into 2027. Work includes removing toll plaza canopies, barrier walls, installing new monotube structures, ramp pavement improvements, shoulder repairs, electrical updates, lighting enhancements, and new signage. On Friday, March 27, eastbound I-90 ramps to Arlington Heights Road will be reduced to a single lane for toll plaza work; westbound I-90 ramps to Barrington Road face similar restrictions starting Sunday, March 29. Weekend detours for equipment installation are also planned later this year.
Closures and detours are being coordinated with multiple agencies including the Illinois Department of Transportation as well as local municipalities such as Cook County; Village of Arlington Heights; Elk Grove Village; Village of Hoffman Estates; Village of Barrington; plus local fire and police departments.
The project is part of Move Illinois: The Illinois Tollway Driving the Future—a $15 billion capital program spanning sixteen years—and Bridging the Future—a seven-year $2 billion plan approved by directors in December 2024. These programs aim to modernize infrastructure across Northern Illinois’s toll system without using state or federal funds for maintenance or operations.
Construction zone speed limits remain enforced around-the-clock in all affected areas. Drivers are reminded that state law requires slowing down or changing lanes when passing vehicles with flashing hazard lights under the “Move Over Law.” Penalties include fines up to $25,000 or jail time for violations involving roadway workers.
