Drivers who use Russell Road in far northwest Lake County lost access to the Lewis Avenue intersection on Monday, July 13, when the Lake County Division of Transportation closed it to all traffic for 90 days. Crews are building the second single-lane roundabout in the Russell Road Corridor Improvement Project.

The 90-day construction window puts the expected reopening around mid-October. LCDOT announced the closure on June 29.

The project, contracted in September 2025, is replacing two traditional intersections with roundabouts along the Russell Road corridor. The first roundabout, at Russell Road and Kenosha Road (47th Avenue), began under its own 90-day closure on April 13. That phase also includes resurfacing Russell Road and adding bike-friendly shoulders between Kenosha Road and Lewis Avenue (39th Avenue).

Chuck Gleason, the project manager for the corridor work, can be reached at 847-377-7447. Paul Guardi, the resident engineer, is available at the field office: 224-656-5919.

St. Mary's Road closing July 28

Closer to Lake Forest, LCDOT will close St. Mary's Road to through traffic between Illinois 137 and Illinois 176 for one day on Tuesday, July 28, beginning at 8:30 a.m., weather permitting. The road is scheduled to reopen by late afternoon the same day, according to LCDOT's July 16 announcement. The closure is for culvert repair.

New left-turn signals on Arlington Heights Road

LCDOT has also activated new flashing yellow arrow traffic signals at intersections along Arlington Heights Road between Lake Cook Road and Illinois 83. The signals allow left-turning drivers to proceed after yielding to oncoming traffic, replacing the older yield-on-green indication. LCDOT says the flashing yellow arrow format is easier for drivers to understand than the traditional setup.

The agency previously installed flashing yellow arrows along the Butterfield Road corridor from Illinois 137 to Allanson Road and said it would monitor performance before expanding elsewhere. The Arlington Heights Road activation marks that expansion.

Adopt A Highway open year-round

Lake County's Adopt A Highway Program now accepts volunteer sign-ups at any time of year, ending a previous enrollment-window requirement. Community groups, businesses, schools, and scout troops can register at lakecountyil.gov/4922.

LCDOT manages more than 300 miles of arterial highways and 59 miles of bike facilities across Lake County. Residents can report road concerns through the agency's online form at lakecountyil.gov.
