Chicago Transit Authority (CTA), along with Mayor Lori Lightfoot, has unveiled the designs for four Red Line stations that will be completely reconstructed under the Red and Purple Modernisation (RPM) Phase One project.

According to CTA, this modernisation project is the largest transit investment in its history and the latest among several Red Line development projects over the past ten years.

CTA will modernise the Lawrence, Argyle, Berwyn, and Bryn Mawr rail stations, renovating them into modern, bigger, and fully accessible stations to disabled passengers.

For this purpose, the stations will feature elevators and escalators, wider platforms, and enhanced amenities.

The $2.1bn RPM Phase One project is the initial part of CTA’s plan to renovate the Red and Purple lines between Belmont and Linden.

After the modernisation of a century-old infrastructure at the Red Line, Phase One work will address the issues of chronic congestion and delays.

In 2019, the Red Line, which is CTA’s busiest, carried nearly 70 million riders.

Mayor Lightfoot said: “Today’s station design unveilings mark a historic day for Chicago transit as we continue to rebuild and revamp CTA’s busiest line, the Red Line.

“Public transit is the great connector of our city and with this monumental project, we are building on our obligation to ensure Chicago’s transportation network is accessible, reliable and affordable so our residents remain connected to jobs, education and opportunity.”

CTA president Dorval Carter said: “CTA’s Red Line forms the backbone of our city and is a critical transportation link for Chicagoans, including essential workers, who need efficient, reliable, and modern service each and every day.

“The RPM project’s benefits extend beyond the project area by improving transit operations and by providing opportunities across the city through training, jobs, and contract opportunities that will be a model for future CTA projects like the Red Line Extension.”

With reconstruction work commencing from Spring 2021, the new stations are expected to open by the end of 2024.

CTA, construction contractor Walsh Fluor Design-Build Team and architectural firm EXP worked closely with locals in surrounding neighbourhoods for the development of designs that create an identity for each station.

During reconstruction work, the Lawrence and Berwyn stations will be shut and temporary rail stations at Argyle and Bryn Mawr will be opened.
