CTA's modernization project begins final major stage

The Chicago Transit Authority (CTA) has put into service two new elevated track structures between the Belmont and Addison stations on the Red and Purple lines.

In the area, the CTA will begin the final major phase of construction for the Red and Purple Modernization (RPM) Phase One Project, which includes fully rebuilding the remaining two, century-old Red and Purple line elevated tracks, according to a news release.

Combined with other project improvements — including the completion of the Red-Purple Bypass in November 2021 and new Red and Purple line track between Lawrence and Bryn Mawr avenues in July 2023 — the RPM Phase One Project has provided nearly 1.4 miles of new track structure. 

Remaining work, including four new Red Line stations at Lawrence, Argyle, Berwyn and Bryn Mawr, is expected to be completed in 2025.

“We are bringing better transit to our customers by modernizing the CTA Red Line, which is the transportation backbone of our city and provides critical transportation to thousands of Chicagoans every day,” said CTA President Dorval Carter Jr. "With new track and four new, fully accessible Red Line stations to open in two years, I am pleased that the RPM project is delivering on its promise to provide world-class transportation to Chicago."

Red and Purple line service will continue throughout the project through completion in 2025.
