The JV of Walsh Construction and VINCI was selected in 2024 as design-build contractor for the 5.5-mile-long project.
After nearly 60 years of discussion, Chicago has broken ground on the $5.7-billion Red Line Extension planned to provide rapid rail transit to the city’s far south side and touted as the largest capital project in the Chicago Transit Authority’s (CTA) history.
The extension will cover 5.5 miles from 95th Street to 130th Street and will include the construction of four new Red Line stations at 103rd, 111th, Michigan and 130th streets. In addition, a new rail yard and related rail facilities near 120th Street are planned to improve operational efficiency for the entire Red Line and CTA system.

The CTA has contracted with workforce assistance agencies including Chicago Women in Trades, HIRE 360 and Metropolitan Family Services.
CTA and design-build contractor Walsh-VINCI Transit Community Partners has committed to creating pathways for Chicagoans to receive training and access to jobs on the project.
CTA included goals in the Walsh-VINCI contract to ensure that small businesses certified as Disadvantage Business Enterprises (DBE) could bid on sub-contract work. Those goals are 25% for project design and 22% for project construction.
“Today’s groundbreaking demonstrates our shared commitment to transit equity and opportunity for every Chicagoan,» said Chicago Mayor Brandon Johnson in a press release. “Far South Side residents have waited decades for this crucial rail service to come to life.»
It is expected that the project will create more than 12,500 construction jobs.
