Chicago's Red/Purple Modernization transit project to begin first major phase

May 4, 2021

Work beginning in May will include reconstruction of century-old CTA track structures

The Chicago Transit Authority (CTA) recently announced the agency will begin on May 16 the first of two phases of major station and track reconstruction between the Lawrence and Bryn Mawr stations.

The work is part of the agency’s $2.1 billion Red and Purple Modernization (RPM) Phase One Project

The RPM project will rebuild the 100-year-old Lawrence, Argyle, Berwyn, and Bryn Mawr Red Line transit stations and tracks. The agency says the new stations will be modern, larger, and fully accessible stations that will include elevators, wider platforms, and vastly improved amenities. CTA will also rebuild the century-old track structure between the four contiguous stations.

The work beginning in May will also include reconstruction of century-old CTA track structures that will provide a faster, smoother and quieter ride for customers. 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 in the community.

The Lawrence to Bryn Mawr Modernization Project will be performed in two stages, Stage A (2021-2022) and Stage B (late 2022-2024), with new stations expected to open near the end of 2024. Work will include demolition of 100-year-old track structure and four Red Line station houses in partnership with contractor Walsh-Fluor. The contractor will also help build new track support systems and new track structure in both phases.

The new bridges and tracks will be built via an overhead gantry system that will install pre-cast concrete bridge segments that are manufactured off-site and trucked into the RPM project area. The construction method minimizes impacts to the community and the area needed by the contractor around the Red Line tracks to perform the construction work.
