CTA's Red and Purple Modernization Project Progresses in Chicago

The Chicago Transit Authority (CTA) has begun the final stage of the Red and Purple Modernization (RPM) Phase One Project. The RPM Project is the largest capital project in CTA's history, focusing on new bypass structures, complete rebuilding of several stations, and installing a new signal system between Howard and Belmont.

The North Belmont Red-Purple Reconstruction aims to rejuvenate the CTA's Red Line, providing over 67 million rides a year in densely populated North Side Chicago neighborhoods, according to Mass Transit. The modernization efforts will improve service and increase rider capacity with updated infrastructure and additional trains to meet ridership demand.

According to Mass Transit, the final stage of the North Belmont Red-Purple Reconstruction (Fall 2023 through 2025) includes rebuilding 0.3 miles of northbound Red and Purple Line elevated track structures between Belmont station on the south, and the stretch of track between Newport and Cornelia avenues on the north. Reconstruction of northbound tracks is underway, and will conclude by 2025.

ABC7 Chicago reports temporary stations will be in place for Argyle and Bryn Mawr during the construction, as Lawrence and Berwyn stations remain closed for renovations. Red, Purple, and Brown Line service will continue throughout the project. However, minor service disruptions are anticipated during the new track installation this fall.
