Update on Bryn Mawr construction

For the residents and businesses who lost power Wednesday and Thursday, ComEd service restoration work continued overnight and power has been restored to most residences and businesses in the community. This includes power at 5534-5548 N Winthrop. Residents evacuated from this building on Wednesday may now return to home because ComEd has restored power and the drill rig behind your building has been stabilized. Please note: There will be a small number of residents on the north side of this apartment building who will need to evacuate the apartment complex for a short period of time in the near future so the contractor can disassemble the drill rig. We don’t yet know when that work will occur, but it will happen soon. We will notify all residents directly who need to temporarily vacate the property, and the contractor will offer hotel room stays as needed.

We are working with the Contractor to further develop and confirm the specifics of this time line and we will keep you informed via email or phone call. If you are a resident of 5534-5548 N Winthrop and need to contact us, please call the contractor directly at (312) 971-7797. Please send any receipts for reimbursement (rideshare rides, etc.) to Marcy Jensen at For any other project questions, please email us at or call (331) 303-2499 for a callback.

For businesses that lost power last night, ComEd service restoration work continued overnight and power has now been restored. If you need to report loss of business, spoilage expenses or other reimbursement concerns, please contact Marcy Jensen at

At about 3:30 p.m. on Wednesday, October 6, a piece of construction equipment fell off the Red Line tracks near Bryn Mawr onto street level. No injuries were reported. After a brief service suspension, Red Line trains resumed service in the evening, and trains are again stopping Bryn Mawr station. The cause of the incident is unknown at this time. CTA is investigating the cause to determine what happened. We will provide updates to you when we have new information to share. If you need to contact us, please email us at or call (331) 303-2499. If you live on the east side of 5500 block of North Winthrop and are without power and have questions, please call (312) 971-7797.

RPM Community Office is now open

CTA has opened a new RPM Community Office at 5137 N. Broadway in the Uptown neighborhood, a central location for residents in the RPM project area that includes Edgewater, Uptown, Andersonville and Lakeview East. The RPM team will have staff to speak directly with residents who are affected by the historic Red and Purple Modernization (RPM) Phase One Project.

RPM_Community_Office_ribbon_cutting_7.26.21_2The new office is intended to serve as a one-stop shop where residents, businesses, stakeholders and the general public can learn about the RPM project, ask friendly staff members questions and let CTA know about their concerns. It serves the entire RPM Phase One project area, including the Lawrence to Bryn Mawr Modernization Project and the Red-Purple Bypass Project zones. It is accessible via the temporary Red Line station at Argyle and the #36 Broadway and #92 Foster buses.

The outreach office will remain open until RPM Phase One is completed in 2025 and will be open Monday, Wednesday and Friday from 10 a.m. to 5:30 p.m. and by appointment.

Visitors to the office can and are encouraged to:

  • Ask questions about the RPM project and CTA
  • Set up in-person appointments with RPM staff
  • Request meetings with live foreign language translators
  • Request project tours
  • Request school visits by RPM staff to learn more about CTA and RPM
  • Participate in events held at the outreach office

Lawrence to Bryn Mawr Stage A: What can you expect?

2021 construction activities and Stage A overview

CTA anticipates the start of new station and track construction to begin in Spring 2021 and construction will be performed in two stages, Stage A (2021-2022) and Stage B (late 2022-2024).

Stage A includes:

  • Lawrence and Berwyn stations close at the start of Stage A and CTA will open temporary rail stations at Argyle and Bryn Mawr to provide customers with access to Red Line service. Red and Purple Line service will continue throughout construction, with train service running on two tracks (the westernmost tracks) instead of the usual four tracks.
  • CTA will demolish the northbound Red and Purple Line track structures (the two easternmost tracks) and begin the demolition of the Lawrence, Argyle, Berwyn and Bryn Mawr stationhouses. The track structures and stationhouses are all around 100 years old.
  • After demolition, CTA will build new track foundation columns on the east side of the CTA track structure.
  • New track structure construction will follow and be constructed with pre-cast concrete segments that are created off-site, trucked in, and installed with a gantry system.


A new Argyle temporary station entrance, above, and a new Bryn Mawr temporary station, right, will open in spring 2021 when Stage A construction begins.

CTA will provide the public with a more updated timeline on the start of Stage A when construction plans are finalized. When Stage A is completed, CTA train traffic will be rerouted to the new tracks so the westernmost tracks and new stations can be rebuilt in Stage B.

See what the new Red Line stations will look like!

Mayor Lori Lightfoot and CTA in January 2021 unveiled new designs for four Lawrence, Argyle, Berwyn, and Bryn Mawr Red Line stations that will be fully reconstructed as part of the Red and Purple Modernization (RPM) Phase One project. The new stations will include elevators and escalators, wider platforms, and vastly improved amenities, better serving the more than four million customers who enter the stations each year. Major construction work will begin this spring. Lawrence and Berwyn stations will close for 3 ½-4 years. Customers will be able to access the Red Line at Argyle and Bryn Mawr via temporary rail stations close to the original stationhouses. All stations are expected to be completed and open by the end of 2024.

Red-Purple Bypass: Building the steel bridge structure

Construction of the new Red-Purple Bypass continues and will be completed later this yearAfter completed the construction of columns last summer, we  began last fall installing steel to form the bridge starting from the south and moving north. In January 2021, we completed the installation of steel over the Red and Purple tracks and in February the steel was extended to west of Sheffield. The bypass will carry Kimball-bound Brown Line trains over the tracks. Learn more here.

After the bypass is finished, the RPM team will begin rebuilding the century-old Red and Purple Line tracks underneath the bypass, between Belmont and between Cornelia and Newport. The new Purple and Red Line tracks are expected be completed by the end of 2024.

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.
