Chicago’s Far South Side has long lacked direct rapid transit access, resulting in longer commutes and limited connectivity. To address this gap, the Chicago Transit Authority proposed extending the Red Line beyond its current 95th/Dan Ryan terminal to 130th Street. The 5.5‑mile extension is designed to serve transit‑dependent communities, improve mobility and support long‑term neighborhood revitalization through new stations, bus connections and parking facilities.

CDM Smith led NEPA scoping, alternatives analysis, and development of the Draft Environmental Impact Statement, coordinating engineering and environmental reviews to support selection of a preferred alignment.
As the key technical lead of the program management team, CDM Smith oversaw property acquisition and relocation for 200+ parcels, environmental due diligence, design oversight, and contract development.
The team led extensive public and agency outreach, coordinating with more than 100 federal, state and local agencies and neighborhood groups through meetings, open houses and hearings.
Through its role across planning, environmental review and program management, CDM Smith has supported CTA in advancing the Red Line Extension from early scoping through design and construction preparation. The project will reduce commute times, improve access to jobs and services, and strengthen connections to bus and regional transit. By integrating engineering, environmental compliance, property acquisition and community engagement, the program is positioned to deliver long-term mobility benefits and support economic revitalization in Chicago’s Far South Side upon completion. The program also includes the new 120th Street Yard and Shop, which will expand system capacity and provide critical infrastructure to support the long-term operation and maintenance of the extended Red Line.
