Red Line Extension

Preferred Alignment

In 2018, based on public feedback received on the Draft EIS as well as subsequent project planning and engineering work, the Preferred Alignment for the RLE project was selected. The Preferred Alignment is a combination of the previously presented Union Pacific Railroad (UPRR) East and West Options. As a result, the RLE project would run along the west side of the Union Pacific Railroad tracks (from I-57 south to approximately 108th Place), cross over the Union Pacific Railroad tracks and run along the east side of the tracks until crossing the Metra Electric tracks (near 119th Street) and continue south to 130th Street. (See the project map.)

The Preferred Alignment captures the benefits and minimizes the impacts of either option. The Preferred Alignment would affect fewer residences than the East Option and fewer businesses and jobs than the West Option. Noise and vibration impacts as a result of the Preferred Alignment would not be greater than those anticipated under either the East or West options.

The RLE project will include the following features:

  • 5.6 mile heavy-rail transit line extension from 95th Street terminal to 130th Street
  • Four new stations at 103rd Street, 111th Street, Michigan Avenue, and 130th Street
  • New Park & Ride, and bus facilities at each station
  • New rail yard and rail maintenance shop

Public open house for the RLE Preferred Alignment

The CTA hosted a public open house on Tuesday, February 13, 2018 at Gwendolyn Brooks College Preparatory Academy to provide information on the Preferred Alignment for the RLE project.

This meeting was conducted in an open house format. The CTA welcomed comments and feedback about the Preferred Alignment and the potential impacts on the community.

Alternatives development history

Red Line Extension Preferred Alignment

The CTA undertook an extensive Alternatives Analysis process from 2006–2009 that considered multiple modes and corridor options for the RLE project.

Starting with multiple modes and corridor options, the CTA developed and screened alternatives through a combination of conceptual engineering, public input (open houses and stakeholder meetings), and preliminary analysis of potential impacts and costs.

The Chicago Transit Board designated the UPRR Alternative as the Locally Preferred Alternative on August 12, 2009.

In preparation for the Draft EIS, and based on the outcomes of the Alternatives Analysis, the CTA evaluated the following alternatives and options from 2012–2014:

  • No Build Alternative
  • Bus Rapid Transit Alternative
  • Union Pacific Railroad Rail (UPRR) Rail Alternative
    • Right-of-Way Option
    • East Option
    • West Option
  • Halsted Rail Alternative

In August 2014, based on the technical analysis and public input until then, the CTA announced the NEPA Preferred Alternative—the UPRR Alternative. Because the Right-of-Way Option is not feasible, the Draft EIS evaluated only the East and West Options for the UPRR Alternative. The Draft EIS summarizes the environmental benefits and impacts of the No Build Alternative and the two UPRR Alternative options.

Based on public feedback, technical analysis, and agency coordination, CTA selected a Preferred Alignment in January 2018. The Preferred Alignment is a combination of the previously presented Union Pacific Railroad (UPRR) East and West Options, which captures the benefits, minimizes the impacts of either option and incorporates the feedback received on the Draft EIS.
