The Chicago Transit Authority (CTA) has selected a design-build team to provide engineering, design and build services for phase one of the Red and Purple Modernization Program.
Stantec will be the lead designer for the Red and Purple Modernization Program. The $2.1-billion project will reconstruct, modernize and build 1.9 miles of elevated tracks, including bridges and support structures along Chicago’s busiest transit corridor.
The design will also include reconstruction and modernization of the four of the oldest rail stations on the Red Line: Lawrence, Argyle, Berwyn and Bryn Mawr. A new rail bypass will relieve congestion at a century-old rail junction north of Belmont Station, where Red, Purple and Brown Line trains carrying 150,000 riders daily intersect, resulting in train overcrowding and service delays.
Chicago has the second-busiest mass rail transit system in the U.S., sections of which are more than a century old.
The project will begin in the first quarter of 2019 and is scheduled to be completed in 2025.
