Walsh Construction, along with joint venture partner Fluor, has been selected by the Chicago Transit Authority (CTA) as the preferred partner to design and build Phase One of the Red and Purple Modernization (RPM) Program. The $2.1 billion project will be the largest capital project in CTA’s history and will deliver improved infrastructure and ridership capacity along Chicago’s most utilized transit lines. A Red-Purple Bypass will modernize the century-old Clark Junction where the Red, Purple and Brown Line trains currently 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 Red and Purple line train speeds through the intersection. The project also includes rebuilding the Lawrence, Argyle, Berwyn and Bryn Mawr stations and all the tracks and support structures for more than a mile adjacent to the stations. New bridges, support structures, tracks and 3.2 miles of signal system upgrades will also be constructed.
