The Chicago Transit Authority (CTA) selected Fluor Corp. and Walsh Construction Co. to design and build the first phase of a $2.1 billion Chicago subway modernization project.

The Red and Purple Line Modernization Program is the largest capital spending project in the history of the Windy City’s transit system. The project includes designing and building new elevated tracks along a 1.9 mile section in the city including new bridges, support structures and existing tracks; and upgrading 3.2 miles of the signal system.

Most notably, a Red-Purple Bypass will modernize the 100-year-old Clark Junction where the Red, Purple and Brown Line trains now intersect at the same grade. The fly-over bypass structure will eliminate train congestion by allowing eight more Red Line trains per hour during rush periods, accommodating up to 7,200 additional customers per hour during rush periods and increasing train speeds through the intersection.

The project also includes rebuilding four of the city’s busiest stations, Lawrence, Argyle, Berwyn and Bryn Mawr, and all the tracks and support structures for more than a mile adjacent to the stations.

Other contractors working on the project include lead designer Stantec Consulting Services, and major subconsultant designers EXP, International Bridge Technologies and TranSmart/EJM Engineering, according to Chicago-based Walsh.

Walsh is already heavily involved in revamping Chicago’s transit system. The company already has a contract to rehabilitate the CTA’s Garfield Green Line Station in the Washington Park neighborhood, as well as the Belmont and Jefferson Park Blue Line Intermodal Facilities. In February the company completed reconstruction of the Wilson Station in the Uptown neighborhood.

Earlier this year, the CTA awarded a $30 million contract to modernize three Blue Line stations.
