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.


New tracks and infrastructure for faster, more reliable rides

The first phase of the RPM Program includes extensive track reconstruction 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 was 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 worked with local stakeholder on potential redevelopment plans for these properties after project work is complete.

Project timeline

  • 2018: Advance utility relocation work began; CTA selected Walsh-Fluor as design-build contractor

  • 2019: Property demolition completed; design work for Lawrence to Bryn Mawr is developed

  • 2020: Significant preparatory work to tracks and construction of temporary stations is performed to prepare for Lawrence to Bryn Mawr reconstruction

  • 2021: Lawrence to Bryn Mawr station closures/reconstructions began with "Stage A", including demolition of stations and northbound track structures; Lawrence, Berwyn stations close for 3 1/2 years

  • 2022: Stage A work continues

  • 2023: Stage B, including rebuilding the southbound track structures and four new stations at Lawrence, Argyle, Berwyn and Bryn Mawr, to begin

  • 2025: Construction expected to be completed


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.
