Chicago Transit Authority Red Purple Modernization Program
Rail & Transit
Ardmore Roderick is part of the Elevated Solutions Partners (ESP) joint venture with Arcadis and Jacobs, as Owner’s Representative for Phase One of the Red and Purple Modernization Program (RPM). RPM is the largest capital investment in CTA history that will modernize train service on the Red, Purple and Brown Lines. Major construction began in October 2019 with the start of construction of a new Red-Purple Bypass north of the Belmont Red, Purple and Brown Line station.
The RPM corridor is a 9.6-mile stretch of track that was built close to a century ago. Most of this infrastructure is at the end of its useful lifespan. Frequent maintenance to repair tracks and remove slow zones is costly and hinders service. The red line is Chicago’s busiest ‘L’ line, serving some of the most densely populated neighborhoods in the country, and the number of riders along this corridor is only growing. With current infrastructure constraints, the red line has reached capacity.
RPM Phase One will completely rebuild the Lawrence, Argyle, Berwyn and Bryn Mawr stations and all the tracks and support structures for more than a mile adjacent to the stations. The stations will be accessible for the first time and include wider platforms, better lighting and modern amenities. The project will also construct a Red-Purple Bypass north of the Belmont train station to modernize the century-old Clark Junction where red, purple and brown line trains currently intersect. The bypass, which will carry northbound brown line trains up and over red and purple line tracks, will eliminate the need for trains to stop and wait for other trains to cross, allowing CTA to significantly increase the number of trains it runs along the red line – reducing overcrowding and meeting a growing demand for transit service.

• Strategic advisory
