PROJECT COMPLETION

WINTER 2026 UPDATE

Work will continue in January 2026 and in the coming months on items that can be completed in winter conditions. When the weather improves in Spring 2026, the final concrete work will be completed in the center medians and the final layers of asphalt will be paved. Traffic will remain in the current Stage 4 configuration with vehicles using the outer two lanes. Please refer to the map below. 

PROJECT BACKGROUND

The Lake County Division of Transportation (LCDOT) is reconstructing Arlington Heights Road, from IL 83 to Lake Cook Road for 1.5 miles in the villages of Buffalo Grove, Long Grove and unincorporated Lake County.
​
The project will replace pavement that was originally built in 1980 and has now reached the end of its useful life. The reconstruction will consist of removing the existing concrete, installing a new aggregate base and replacing the roadway pavement with brand new asphalt. The purpose of the project is to not only address the roadway condition but to also improve safety and provide a more accessible roadway for pedestrians, motorists and all other users in the community.
