CTA plans major changes for Clark/Lake station

The Chicago Transit Board today approved an amendment to an agreement with JRTC Holdings, comprised of The Prime Group and Capri Investment Group, who are redeveloping the former James R. Thompson Center, which will result in major changes for the Clark/Lake Loop Elevated station.

With more than 9,100 average weekday entries, the Clark/Lake station is one of the busiest stations across the CTA, with the elevated platform serving five of the agency’s eight rail lines -- the Brown, Green, Orange, Pink and Purple lines, while the subway platform serves the Blue Line.

As part of the amended agreement, CTA and JRTC have agreed to a change of easement for the property that will relocate the main station entrance from Lake Street, under the elevated tracks, to the northeast corner on Clark Street. Included in the project plan will be improvements to the station’s mezzanine finishes to align with the design plans JRTC is spearheading for the overall facility.

“This is a historic renovation project that will not only restore the luster to one of Chicago’s most iconic downtown buildings, but also to the station that is the heart of the city’s public transit system,” said CTA President Dorval R. Carter, Jr. “This collaborative investment project reflects a shared commitment to the future of Chicago transit, and we look forward to continuing our work with JRTC in creating a modern, welcoming station for all who rely on our system for their regular commutes or while visiting our great city.” 

“Like the Thompson Center itself, which has been one of Chicago’s most vibrant and busy spaces since it opened in 1985, the Clark/Lake station is vital and hardworking. It not only connects six rail lines but also links to six major CTA bus lines—making it ‘ground zero’ for Loop access and a reminder of the significance of this entire project,” Prime|Capri co-principal and Capri Investment Group Founder and Executive Chairman Quintin E. Primo III noted. “As partners in this project with the CTA, we’re putting effective and consequential infrastructure in place that will help revitalize the Loop and make it a better place to live, work and play.”

All work and costs associated with the relocation of the station entrance and upgrading the mezzanine finishes are part of JRTC’s overall facility renovation. Complementing these efforts, CTA will be planning $10 million in improvements for the elevated platform. The overall project will be executed in the following three phases between late 2025 and late 2026.

Phase 1, which will entail the station entrance, will begin in November 2025. Phase 2, encompassing the remaining scope, will begin in June 2026. Finally, Phase 3, which will include the CTA platform work, will occur in late 2026.
