Who is the lead agency of this project?
The Cook County Department of Transportation and Highways is the lead on this project and is working in partnership with Lake County and the villages of Buffalo Grove and Wheeling.
Who is funding this project?
The Cook County Department of Transportation and Highways secured $22 million in federal grants through IDOT and $6 million in funding by partnering with the villages of Buffalo Grove and Wheeling and Lake County to improve Lake Cook Road. This project is a key example of how Connecting Cook County, the County’s long-range transportation plan, is working to help accelerate economic growth and foster thriving communities by alleviating roadway congestion, improving pedestrian access/safety, and capitalizing on the taxpayers’ investment by levying Cook County’s funds with federal, local municipality, and private business funding in the area.
Where is this project located?
The proposed improvements will begin at Raupp Road and extend 1.5 miles east to Hastings Lane. In its current state, Lake Cook Road decreases from 6-lanes to 4-lanes at Hastings Lane, causing congestion issues for residents and commuters. This project will widen the 1.5-mile stretch, adding an additional lane in each direction and dedicated turn lanes at each intersection to improve traffic flow and decrease congestion.
Why is this construction project happening?
Currently, this segment of Lake Cook Road presents several challenges for safety and mobility. There are safety concerns along Lake Cook Road and intersections for motorists, pedestrians and bicyclists, because of a lack of bicycling and pedestrian facilities and ADA compliant crosswalks. There are also concerns about growing traffic congestion due to heavy commuter traffic along Lake Cook Road and arterial roads. Major intersections including Buffalo Grove Road and IL 83/McHenry Road need added capacity and designated turn lanes to accommodate growing traffic volume. Commuter congestion during the afternoon rush hour becomes exacerbated due to the existing lane reduction on Lake Cook Road from a 6-lane roadway down to a 4-lane roadway east of Lexington Drive. Because of these concerning issues, Cook County’s 2019-2024 Proposed Transportation Improvement Program identifies Lake Cook Road as a critical expansion project. When completed, the Lake Cook Road Reconstruction Project will alleviate these issues.
Is this project a part of the other roadway projects in the area?
No, this project is different than the Lake County’s Weiland Road Improvement Road project which includes improvements from Woodstone Drive to Deerfield Parkway and from Deerfield Parkway to Aptakisic Road.

When will construction start?
Construction on this project is expected to begin the week of February 3, 2020.
How long will construction take to be completed?
The project will take place in multiple stages and is expected to be completed by 2022. Pre-Construction Stage 1 began in 2019 which included relocation of utility services and award of the construction contract.
Construction Stage 2 will be completed in 2020–this includes the reconstruction of portions of Lake Cook Road, Buffalo Grove Road, IL-83/McHenry Road, and Weiland Road. This also includes construction of a Weiland Road extension to Buffalo Grove Road, and the addition of a noise abatement wall.
Construction Stage 3 will be completed in 2021–this includes the reconstruction of the remaining sections of Lake Cook Road, Buffalo Grove Road, IL-83/McHenry Road, and Weiland Road. This also includes the addition of a noise abatement wall, permanent traffic signals and installation of street lighting.
By 2022, Construction Stage 4 will include the beautification of the project area, updated landscaping along Lake Cook Road, and project completion.
