Project Initiated

The Chicago Transit Authority (CTA) has initiated the Blue Line Forest Park Branch Feasibility/Vision Study. The study is being undertaken to determine a long-term planning strategy for the Blue Line Forest Park Branch, with study limits including the entire Blue Line Forest Park Branch from Clinton station to Forest Park station, including the evaluation of potential expansion alternatives proposed by the Illinois Department of Transportation (IDOT) through their adjacent I-290 Environmental Impact Statement (EIS) Study that would continue to Mannheim Road. The study area street boundaries extend from a block east of Clinton station at Canal Street on the east to Mannheim Road on the west, and between Madison Street on the north to Roosevelt Road on the south.


Project overview

Project background

The Forest Park Branch Feasibility/Vision Study began in 2013. The work has been conducted in coordination with alternatives prepared for two ongoing Illinois Department of Transportation (IDOT) studies, including the I-290 Environmental Impact Statement (EIS) and the Circle Interchange Rehabilitation Project. The CTA’s study involves the assessment of transit and highway integrated enhancements, regional mobility issues, and the identification of funding sources and future collaboration opportunities. Concepts for all stations in the study area include, but are not limited to, station access, redesign opportunities, and right-of-way (ROW) needs at specific stations along the corridor. The study explores innovative solutions that preserve transit, but also integrate highway and transit operations to maximize mobility in this important regional corridor.

The Blue Line Forest Park Branch Feasibility/Vision Study study area includes the CTA Blue Line Forest Park branch and an expanded area to the west to evaluate proposed IDOT high-capacity transit expansion alternatives. Specifically, from east to west, the study area is from Canal Street (one block east of Clinton Station) to Mannheim Road. From north to south, the study area is from Roosevelt Road to Madison Street.


Study process

1: Data Collection and Existing Conditions Assessment
This stage of the project development process includes: assessing existing conditions and deficiencies within the study area corridor; reaching out to local stakeholders and other interested parties about the project; and hosting a public open house to identify study area issues/concerns.

2: Develop Conceptual Alternatives
This stage of the project consists of the development and analysis of project alternatives. The goal of this step will be to identify a series of alternatives and potential solutions that are suitable to meet project and stakeholder goals that were identified in Step One.

3: Evaluate and Refine Alternatives
The process will continue with the evaluation and refinement of the remaining corridor service alternatives.

Project schedule



Get involved

Public involvement

Stakeholder involvement will be a key component in the preparation of the Forest Park Branch Feasibility/Vision Study. A stakeholder is defined as anyone who could be affected by the project and has a stake in its outcome. The CTA will be looking for focused and direct input from all interested stakeholders throughout the study process.

There will be several methods for the public to become involved and obtain information about the project. These methods will provide information and opportunity for feedback regarding upcoming public meeting events, project schedule, and general project status updates within the study area.

Outreach meetings

The Blue Line Forest Park Branch Feasibility/Vision Study will include stakeholder outreach to solicit input on and achieve a general understanding of the issues, and to identify potential solutions for the project. Stakeholder outreach is being coordinated with the ongoing I-290 EIS, and Blue Line Feasibility/Vision Study findings and input opportunities will be added to IDOT’s ongoing stakeholder outreach program. CTA has provided project updates and participated in Public Meetings on October 7 and 8, 2013, I-290 EIS Corridor Advisory Group meetings throughout 2013, 2014, 2015 and 2016 and an Open House on June 29, 2016.

The purpose of the meetings will be to gather the thoughts and concerns regarding the information presented. Questions raised by meeting participants, depending on the nature, will be either answered immediately or addressed in subsequent meetings, letters or other communication mechanisms. Comments received at the public meetings will be documented, and the information will be considered as a part of the analysis and evaluation of the proposed alternatives. Individuals on the mailing list will receive invitations in the mail announcing future meetings.

The next outreach opportunity in the Blue Line Forest Park Vision Study process will be a Public Hearing in January 2017, in coordination with the IDOT’s I-290 EIS Study. CTA and IDOT will jointly present final study recommendations from the two projects in the multimodal corridor.

Upcoming Public Hearing location and dates:

January 25, 2017 5:30-8:30pm
Proviso Math and Science Academy
8601 W Roosevelt Rd
Forest Park, IL 60130

January 26, 2017 5:30-8:30pm
Marriott Chicago, Medical District
625 S Ashland Ave at Harrison St
Chicago, IL 60607

After the Public Hearings, CTA will address and/or incorporate any additional public comments and complete the Blue Line Forest Park Branch Vision Study in mid-2017.
