Red Ahead: Red & Purple Modernization


Lawrence-Bryn Mawr Modernization Project

The first phase of the Red and Purple Modernization (RPM) Program will completely rebuild the Lawrence, Argyle, Berwyn and Bryn Mawr stations and all the tracks and support structures for more than a mile adjacent to the stations. 

See 3D project animation here.

To rebuild the Lawrence, Argyle, Berwyn and Bryn Mawr stations, we temporarily closed the Berwyn and Lawrence stations in spring 2021 to begin reconstruction of the stations and track structure between the stations. We opened temporary stations at Bryn Mawr and Argyle to provide Red Line access to our customers. We expect the new stations to reopen by 2025.

Lawrence to Bryn Mawr Open Houses January 2020

Thank you to everyone who came to our Lawrence to Bryn Mawr open houses on 1/28 and 1/30! In case you missed it, here are the meeting materials that covered important topics like "Why the project is necessary" to "What to expect this year" to "When does new station and track construction begin?":

RPM and Lawrence to Bryn Mawr overview:

2020: Preparing for new station and track construction, or "pre-stage" work

Late 2020/Early 2021 thru 2025: New station and track construction

New stations and full ADA accessibility

While CTA has made some improvements to these stations in recent years, the main support structures for all four stations were built in the early 1900s. All have very narrow station platforms that prevent CTA from adding critical upgrades like elevators. These stations will be completely torn down and rebuilt from the ground up. This will allow CTA to expand and modernize the stations and ensure they are full ADA accessible to customers with disabilities.

Additional amenities at the stations will include:

  • Wider platforms for faster boarding and less crowding
  • Better lighting and customer security features
  • Longer canopies, more benches, and wind screens
  • Real-time information boards

New tracks and infrastructure for faster, more reliable rides

The first phase of the RPM Program will also include extensive track work that will create a faster, smoother, and quieter ride for customers along what are now aging, slow-zone-plagued tracks. New track, support structures, bridges, and viaducts will be built along the approximately 1.3-mile segment between Leland and Ardmore Avenues, eliminating many deteriorated structures that have become neighborhood eyesores.

The reconstruction of stations, tracks, and infrastructure will benefit the 28,000 daily trips that begin or end at the four stations in this corridor, the 45,000 people that live within a ½ mile of these stations, and the almost 80,000 train trips that travel through this area every weekday. This project is intended to not only improve transit service but also support economic development initiatives and encourage redevelopment within Uptown and Edgewater.

Potential redevelopment

Some property acquisition will be required to implement this project. Following construction, we will solicit proposals to sell remaining parcels of land for new retail and residential development. There is growing demand for Transit Oriented Development (TOD) in Chicago neighborhoods, and we have already begun working with local stakeholders to begin planning redevelopment of these properties after project work is complete.

Environmental Assessment

The National Environmental Policy Act of 1969 (NEPA) is a federal law that mandates the consideration of environmental impacts before approval of any federally funded project that may have significant impacts on the environment or where impacts have not yet been determined.

The NEPA process provides a decision-making framework to consider the purpose and need for a proposed action, potential design solutions, project costs, environmental impacts and relative benefits of the proposed action.

FTA and CTA published an Environmental Assessment (EA) for the Lawrence to Bryn Mawr Modernization Project on April 29, 2015, established a 30-day public comment period to accept formal comments, and hosted a public hearing on May 14, 2015.

Based on a review of the EA and all public comments received, FTA issued a Finding of No Significant Impact (FONSI) for this project. The FONSI documentation includes responses to comments received as well as suggested mitigation measures to minimize the environmental impacts of the project, including impacts to historic resources.

Supporting documents related to the EA process are provided below. The issuance of the FONSI means that CTA has identified all potential impacts and ways to minimize and mitigate those impacts and that based on that information, FTA has found that there would be no significant impacts resulting from implementation of this project. The FONSI is required before CTA can receive federal funding to construct the project.
