IL 83 / 137 Study

The Illinois Department of Transportation (IDOT) would like to thank everyone who participated in the Virtual Public Outreach for the Preliminary Engineering and Environmental Study (Phase I) for the improvement of Illinois Route 83 (IL 83) from Illinois Route 132 (IL 132) to Illinois Route 120 (IL 120) and Illinois Route 137 (IL 137) from IL 83 to east of US Route 45 (US 45) in Lake County. Instead of hosting a regular Public Meeting, IDOT shared details on the project and encouraged public participation from June 25th to July 16th, 2020 through a new interactive website.

At the new interactive website, the public had the opportunity to learn more, watch a video about the project, explore an interactive map, and leave comments. In addition to the website, the Department also sent out a project newsletter to impacted residents and had the opportunity to ask questions to Department staff over the phone by calling (847) 636-2343. Written comments that were submitted through the interactive website, made on the interactive map, mailed, or submitted to the project website will now be reviewed and considered in refining the preferred alternative.

Update March 2020:  The project team held the Community Advisory Group (CAG) Meeting #5 on February 24, 2021.  To view materials from the CAG Meeting #5, click below:


Overview and Scope

IDOT is studying potential improvements to approximately 11 miles of Illinois 83 (Milwaukee Avenue/Barron Boulevard) and Illinois 137 (Buckley Road) in Lake County. This section of IL 83/IL 137 is located in the communities of Lake Villa, Round Lake Beach, Grayslake and Libertyville.

In this region, IL 83 and IL 137 serve as a main north-south corridor. IDOT has initiated this study because of the importance of these roadways in servicing the local and regional traffic.

The existing IL 83 and IL 137 roadway alignments vary throughout the study area and include:

  • Two to five lanes
  • Turning lanes to access businesses, residences and other facilities
  • No shoulder to 8-foot-wide shoulders
  • Bicycle paths, sidewalks and pedestrian crosswalks in select locations

The study area includes residential, commercial areas, green space and limited industrial areas. Some notable community features include:

  • Natural areas, including Rollins Savanna Forest Preserve
  • Cultural resources, including Angola and Avon cemeteries
  • Parks, including Fox Chase Park
  • Schools
  • Churches
  • Businesses
  • Residences

The Illinois Department of Transportation (IDOT) develops highway transportation improvement projects in 3 phases. The IL 83/137 study is currently in Phase I. During this phase, preliminary engineering and environmental studies are completed to develop an improvement of the roadway that addresses an established purpose and need for the contract.

The Preferred Alternative received NEPA concurrence on September 20, 2017.  Since then, the Study Team has been moving forward with the refinement of the Preferred Alternative Design and the completion of the Environmental Assessment (EA). The Study Team will be soliciting input from the public on the Alternatives Carried Forward and Recommended Preferred Alternative during the public outreach event scheduled for June 25, 2020 through July 16, 2020.  A Public Hearing is tentatively scheduled for the Fall of 2020.


IDOT develops and implements projects using a three-phase process:

  • Phase I: Preliminary engineering and environmental studies
  • Phase II: Contract plan preparation and land acquisition
  • Phase III: Construction

The IL 83/IL 137 preliminary engineering and environmental study (Phase I) has been funded. This funding was provided in previous IDOT fiscal-year programs. The contract plan preparation phase (Phase II) is currently funded and will begin upon completion of the Phase I study. Funding for land acquisition (Phase II), construction (Phase III), and construction engineering (Phase III) is not currently included in the Department’s Fiscal Year 2021-2026 Proposed Highway Improvement Program. Funding for this project will be considered among similar improvement needs throughout the region. Once additional funding is identified, the land acquisition process is anticipated to take 18 to 24 months to complete and construction is anticipated to take 24-36 months to complete. Due to the funding uncertainty, it is difficult to estimate the future construction schedule.

Phase I: Preliminary Engineering and Environmental Studies
During this phase, IDOT studies a broad range of alternatives, including a “no build” option, to improve IL 83/IL 137 in the study area. IDOT also conducts environmental analysis to comply with the National Environmental Policy Act (NEPA). The project team will collect information, analyze the alternatives and identify potential effects to study area resources. The results of these studies will be presented in an Environmental Assessment (EA) and Combined Design Report. Learn more about NEPA.

  • Evaluate and compare alternatives

Determine Preferred Alternative

  • Select Preferred Alternative
  • Conduct a Public Hearing
  • Prepare the Final Environmental Assessment and Combined Design Report
  • Issue the Finding of No Significant Impact
Context Sensitive Solutions

A key planning tool for this study will be a stakeholder involvement program based upon the principles of Context Sensitive Solutions (CSS). CSS is an interdisciplinary approach that seeks effective, multimodal transportation solutions by working with stakeholders to develop, build and maintain cost-effective transportation facilities which fit into and reflect the project’s surroundings (its “context”).

Through early, frequent, and meaningful communication with stakeholders and a flexible, creative approach to design, the resulting project should improve safety and mobility for the traveling public while seeking to preserve and enhance the scenic, economic, historic, and natural qualities of the settings through which they pass. CSS stakeholder activities will include Community Advisory Group (CAG) meetings, meetings with special interest groups, and public meetings as well as a public hearing. All input will be evaluated and used to help shape viable solutions.

The CSS project approach enhances public participation in the transportation planning process.


This project is being developed in accordance with the National Environmental Policy Act (NEPA)

The purpose of the NEPA is to ensure that environmental factors are weighted equally when compared to other factors in the decision making process.


Get Involved

The study includes multiple opportunities for you to participate by submitting comments, attending public meetings and keeping informed through this website and newsletters. We will update this website as the IL 83/IL 137 Study progresses to help you stay informed.

Your participation and input are vital to the success of the study. We value your input and look forward to your participation. To get involved:

  • Join our Mailing List
  • Submit Comments
  • Review materials on the Resources page
  • Attend a Public Meeting
  • Volunteer to be on the Community Advisory Group

We are engaging the community in the following ways:

  • Community Advisory Group
  • Small group/individual meetings
  • Public meetings
  • Briefings and presentations
  • Informational materials
  • Media releases

Because stakeholder involvement is critical to the planning process for this study, a Stakeholder Involvement Plan (SIP) has been developed to guide the stakeholder involvement program.

Community Advisory Group

IDOT has formed a Community Advisory Group (CAG) to ensure the values and interests of the community are incorporated into project solutions.

The CAG supports the CSS approach and stakeholder engagement program during the planning process. The CAG will be comprised of community leaders, including elected officials, representatives from local municipalities, homeowners, business owners, and local special interest groups.

The CAG ensures that identified solutions balance community, technical and long-range planning needs. It also assists in keeping the project on the right track with respect to implementation. The CAG will provide input at key milestones throughout Phase I of the planning process. CAG meetings will be designed to encourage timely and meaningful input by members.
