RPM Lawrence to Bryn Mawr Modernization: Pre-stage work and service reroutes Summer 2020

We are getting closer to starting construction of four new stations and tracks between Lawrence and Bryn Mawr as part of the Red and Purple Modernization (RPM) Phase One Project!

captionThat work is on schedule to begin around the end of the year, but there is work we must do today in order to provide Red and Purple Line service during new station and track construction (2021-2024) – and some of this work will have temporary impacts to CTA Red and Purple Line service starting on Friday, June 5, 2020.

***Note: the Lawrence to Bryn Mawr Modernization Town Hall has been rescheduled to July 14, 2020.***

CTA this year began making track improvements on the Red and Purple lines near the Thorndale station and on the track structure at Montrose Avenue that will provide quicker train service, and prepare the tracks for service during new station and track construction.

RPM includes the construction of new track structure and stations, replacing 100-year-old infrastructure and building modern stations with elevator access. That work will begin by early 2021, and in order to provide Red and Purple Line service durng construction we are making track upgrades now. The work will have impacts on CTA service in 2020, including weekday service this spring and summer.

Q. How will the 2020 trackwork affect my commute?

Much of our work to date has been on weekends only, and has required trains to occasionally skip stations; other weekends we have had to temporarily close Granville, Thorndale and Bryn Mawr. We provide free bus shuttle service during the latter scenario.

What is new is that we anticipate having to do some weekday work as well. That is expected to consist of one three-week Red/Purple reroute and two separate one-week Red/Purple service reroute that will result in:

June 5-29: No 95th-bound service at Lawrence and Argyle on nine non-contiguous days and some additional skipped station stops on weekends.

July 17-Aug. 9: No station stops at Thorndale in one direction on weekdays and some skipped station stops on weekends.

Q. Will travel times be impacted?

A. We strongly encourage our customers to plan ahead for longer commutes by allowing extra travel time, changing travel patterns such as traveling earlier or later than peak rush periods or considering using alternate service such as the #36 Broadway bus.

 Q. When do Lawrence, Argyle, Berwyn and Bryn Mawr fully close for reconstruction?

A. We expect to begin building new stations and track structure by early 2021, with new stations expected to open by the end of 2024. Temporary stations at Argyle and Bryn Mawr will serve customers throughout construction.

Q. How will I know if my station is open or closed during the 2020 trackwork?

A. There will be signs and announcements on trains and at stations. Additionally, this information will be available on our web site at We encourage you to sign up for our construction alerts at

Information for Purple Line riders

Purple Line and Purple Line Express service will also be affected by the RPM trackwork in 2020 scheduled for June 5-29 and July 17-Aug. 9. During these periods, weekday Purple Line Express trains will run on the same tracks as the Red Line.

Purple Line Express trips between Howard and Belmont are expected to increase by as much as 10 minutes more than usual, and Express service may run slightly less frequently. Additional details on the exact impact to train schedules are being prepared and will be published when finalized.

Lawrence to Bryn Mawr Modernization: Update


Thank you to everyone who attended our Lawrence to Bryn Mawr Open House meetings earlier this year in the Uptown and Edgewater neighborhoods! We enjoyed talking to you about this project and what's coming up in your community. Here is a project Q&A and other materials to take a look at.

What is the work that's being done in 2020?

In 2020, there will be trackwork performed between Montrose and Thorndale to prepare for the Red and Purple Modernization (RPM) Project, rebuilding century-old track structure and train stations to improve service for our customers. This trackwork, beginning the weekend of Jan. 24-27, 2020 and continuing most weekends through the winter and spring months, will affect CTA service.

This includes rebuilding the Lawrence, Argyle, Berwyn and Bryn Mawr stations into new, larger modern stations that have elevators to make the stations fully accessible to customers with disabilities. It also includes rebuilding century-old track structure between the stations.

This trackwork will have impacts on our Red Line service on weekends throughout the first half of 2020, including some station closures. Please read more about this work here.

Major station reconstruction, including closing Lawrence, Argyle, Berwyn and Bryn Mawr, is still anticipated for the end of 2020 or early 2021. At that time, we will open temporary rail stations at Argyle and Bryn Mawr to provide rail access between then and when construction is completed, expected at the end of 2024.

CTA, Walsh-Fluor Hold Electrical & Track Outreach Event Dec. 12

CTA and the Walsh-Fluor Design Build Team held an RPM  Phase One Electrical & Track Outreach Event"  December 12, 2019 (2 p.m.-4 p.m.) at  The Northside American Job Center at Truman College, 1145 W. Wilson Avenue.

Construction of the Red Purple Modernization (RPM) Phase One Project, the largest capital improvement project in CTA’s history is under way and will continue through 2025. In anticipation of upcoming electrical and track opportunities, the Walsh-Fluor Design-Build Teams held a DBE and Workforce outreach event to allow interested parties to network and connect with  the subcontractors who will be performing the electrical and advanced track work, as well as learn about upcoming lower-tier subcontracting and workforce opportunities. Attendees were able to network with union representatives, job assistance agencies and  learn how to become eligible and equipped to work on construction projects throughout Chicago like RPM.




RPM construction has begun!

Better CTA service is coming! We've broken ground on the transformational Red and Purple Modernization (RPM) Phase One Project, with work beginning on a key component of RPM, the Red-Purple Bypass north of Belmont station. The bypass will allow for more trains, less congestion and a less cramped commute to work.

The modernization project has many steps, and it is important to know when and how you or your business may be affected.  Sign up for construction impact alerts in your community here.

How are we building the Red-Purple Bypass?



Last summer we held construction open house meetings in the Red-Purple Bypass Project Area. Check out our press release here. For materials from the event, click here.

We will continue to keep you informed as this project moves forward. Learn more about this project by clicking here for meeting materials or email us at and we'll be glad to talk with you.




CTA, RPM contractor hold first-ever RPM Construction

Careers Networking Fair 8/28

CTA is committed to providing access to career training and more through the Red and Purple Modernization (RPM) project! CTA and Walsh-Fluor, the RPM contractor, recently held its first RPM Construction Careers Networking Fair with more than 170 attendees, who learned about training and apprenticeship opportunities that could lead to construction jobs on RPM and other projects.

We thank Walsh-Fluor and its contractors, Chicago’s construction trades and our workforce assistance agency partners for joining us and helping us expand opportunity across Chicago. Stay tuned – we’ll have more events like this in the future! Want to learn more? Email us at




We brought on 14 talented, hard-working college and high school interns to work on this project and take the lessons they learn back to the classroom and with them as they progress in their careers.

May 2019: RPM hosts first 'Meet the Contractor' public meetings; publishes responses to audience questions  


Thank you! 

We are grateful to everyone who has been taking part in the transformation of CTA’s Red Line! Thank you to all of our customers and neighbors who attended our recent “Meet the Contractor” meetings for the CTA’s Red and Purple Modernization (RPM) Phase One project. Scroll down for links to informational project materials!

Through six meetings with more than 200 businesses and residents in the Edgewater, Uptown and Lakeview communities, we introduced the RPM project’s contractor, Walsh-Fluor, to the public and provided an update about the project. Equally important to us was to hear from everyone, which is why we dedicated time at each of these meetings to answering questions that ranged from parking to temporary station plans to street closures.

While we couldn't answer all questions because we’re still working on project design and construction schedules, please know that our work is not yet done. We will provide project updates later this year for both the Red-Purple Bypass area work as well as the Lawrence to Bryn Mawr project work. We look forward to updating you soon to help you prepare for the changes to come.
