Welcome to the Project Website for Old McHenry Crossings!


Special thanks to everyone who took part in the Virtual Public Forum, which was open from September 30th to October 15th. We value and appreciate the insights, concerns, and ideas shared from all community members. At this time, the project team has collected and is summarizing the inputs received. A summary will be posted back to the project website. Click here to view the closed virtual public forum. In the meantime, community feedback is still welcome and encouraged. Please direct input to the interactive map and comment form.

-Thanks again from LCDOT and the Project Team.

The Lake County Division of Transportation (LCDOT) is studying potential improvements to the areas surrounding the Old McHenry Road and Canadian National (CN) Railroad Crossing and along Quentin Road. Four highly traveled regional highways converging to this area, frequent trains and three closely spaced intersections along Old McHenry Road have led to high traffic volumes and delays. Approximately 25,000 vehicles pass through the corridor each day and nearly 370 crashes have occurred in this area over the last five years. For these reasons, this corridor has been identified in the Lake County 2040 Transportation Plan, which recommends improvements necessary to address the future transportation needs of Lake County.

LCDOT seeks to improve safety, traffic operations and connectivity for motorists, bicyclists, and pedestrians within and surrounding the Old McHenry Road and CN Railroad area and along Quentin Road. The project will evaluate the feasibility of constructing a new grade separation at the CN Railroad tracks, meaning motorists will not have to sit and wait for the nearly 20 trains that pass through each day.

The project study area generally includes:

  • Old McHenry Road, Abbey Glenn Drive to Bonnie Lane
  • Quentin Road, IL Route 22 to Old McHenry Road
  • Midlothian Road, north and south of the Old McHenry Road intersection
  • Fairfield Road, north of the Old McHenry Road intersection
  • Echo Lake Road, south of the Old McHenry Road intersection

The project is in the Villages of Hawthorn Woods, Lake Zurich, Kildeer, and in unincorporated Ela Township. The project area bypasses neighborhoods, including the Forest Lake Community Association.
