Chicago Transit Authority (CTA) Red & Purple Modernization (RPM) Program

The Chicago Transit Authority’s Red and Purple lines have reached the end of their useful lifespans, with most tracks and bridges being close to 100 years old. The operation of two rail lines, one of which is the busiest line providing 24/7 service, on such outdated infrastructure has resulted in the need for frequent repairs that disrupt service and slow travel, as well as exceedingly high maintenance costs and outdated stations that are unable to accommodate modern amenities for CTA customers.

The RPM Program aims to double passenger capacity and will bring the rail lines into good repair for the next 60 to 80 years. Benefits include reduced travel times, improved access to job markets and destinations, and improved access to people with disabilities.

The multi-phase RPM Program will rebuild a 9.6-mile stretch of track, stations, and other structures. The program is currently in Phase I, which includes the following significant projects:

Lawrence to Bryn Mawr Modernization Project: This expansion and modernization project involves rebuilding the tracks and support structures along and throughout the Lawrence, Argyle, Berwyn, and Bryn Mawr stations.

Red-Purple Bypass Project: This includes the construction of a rail bypass north of the Belmont station, allowing CTA to address capacity constraints caused by an outdated rail intersection used by three rail lines.

JWI staff provide Quality Assurance/Quality Control management and inspection services for all electrical work for projects under Phase I.
