Lane reductions and traffic shifts scheduled for I-90 Arlington Heights and Barrington Road interchanges

The Illinois Tollway announced on March 24 that lane reductions and traffic shifts will begin next week at the Arlington Heights Road Interchange and Barrington Road Interchange on the Jane Addams Memorial Tollway (I-90) as part of ongoing toll plaza upgrades. The work, which includes removing canopy structures and making plaza improvements, is expected to continue into 2027.

These changes are intended to improve traffic flow and operations at two key interchanges along I-90. Electronic message signs and construction signage will be used in advance to alert drivers about lane closures and changing traffic patterns. Up-to-date information will be available on the Illinois Tollway website's Daily Construction Alert.

Extended lane reductions are planned through the end of this year at the Arlington Heights Interchange on westbound I-90, while similar work at the Barrington Road Interchange on eastbound I-90 is set to last into 2027. The construction involves removal of toll plaza canopies, installation of new monotube structures, ramp pavement repairs, shoulder work, electrical updates, lighting enhancements, and improved signage.

Specific closures include a reduction to a single lane for eastbound I-90 traffic exiting onto Arlington Heights Road starting Friday, March 27. Similarly, westbound I-90 traffic exiting onto Barrington Road will be reduced to one lane beginning Sunday, March 29. Additional weekend-long detours are planned later in the year for toll equipment installation.

Coordination with local agencies—including the Illinois Department of Transportation; Cook County; municipalities such as Arlington Heights, Elk Grove Village, Hoffman Estates, Barrington; as well as local fire and police departments—is underway to manage closures safely. The improvements are part of Move Illinois: The Illinois Tollway Driving the Future—a $15 billion capital program—and Bridging the Future—a $2 billion plan approved in December 2024 by the agency’s board.

Motorists are reminded that construction zone speed limits apply at all times in these areas. The "Move Over Law" requires drivers to change lanes or slow down when passing vehicles with hazard lights activated. Penalties for violations include fines up to $25,000 or jail time if workers are struck.
