Red-Purple Bypass Project SUMMARY Chicago, Illinois | May 2015 Chicago Transit Authority Executive Summary PROJECT SUMMARY Introduction and Project Overview The Chicago Transit Authority (CTA) is undertaking an initiative to completely rebuild the northern portion of the Red Line from Belmont station to Howard station and the Purple Line from Belmont station to Linden station. The Red and Purple Modernization (RPM) Program would fully replace old, deteriorating infrastructure and stations along Chicago’s busiest rail line, paving the way for CTA to significantly increase train capacity and improve service for generations to come. RPM Phase One This massive, multistaged program would be completed in phases and would provide riders with all the benefits of modern service and infrastructure when complete. As part of the program, the Federal Transit Administration (FTA) and CTA have been analyzing proposed improvements to the line. Phase One of the RPM Program includes the Red-Purple Bypass Project and the Lawrence to Bryn Mawr Modernization Project. Within the RPM corridor, Phase One also includes corridor signal and other interim track improvements, which are not anticipated to have any significant environmental impacts. CTA is developing preliminary designs for these interdependent projects, while each undergoes separate environmental review. This Environmental Assessment (EA) covers the Red-Purple Bypass Project. Red-Purple Bypass Project The Red-Purple Bypass Project would construct a fifth track bypass just north of Belmont station where the CTA rail system Red, Purple, and Brown line tracks converge at an existing flat junction. Improvements would also include reconstruction of approximately 0.3 mile of the mainline Red and Purple line tracks from Belmont station on the south to the segment of track between Newport and Cornelia Avenues on the north. This project would modernize infrastructure and expand capacity, reduce passenger travel times, and improve system mobility and safety at one of the largest bottlenecks in the CTA rail system.

General rail transit design guidance recommends junctions be grade separated when trains operate as frequently as they do through Clark Junction. The number of trains CTA needs to operate to meet crowding standards in the peak hour is already within the range of maximum capacity at Clark Junction, and demand has been growing. Red-Purple Bypass Project 3 Project Summary Alternatives Development Process The proposed project evaluated in this EA was developed and evolved through a multiyear planning process that began in 2009. From 2009 to 2013, CTA has continued to refine the Build Alternative based on technical analyses and through continual dialogue with the community. 2009–2010 2011 2012 2013 2014 Research and RPM Phase One NEPA Scoping Alternatives RPM Vision Study Concept Design Definition and NEPA Process Refinement Process Reviews • 2009–2010: CTA conducted a vision study • 2012: CTA held two community update meetings between fall 2009 and fall 2010 to understand in early 2012, which allowed attendees to the public’s priorities and concerns, conduct learn about refined alternatives for the RPM an existing conditions analysis, and frame corridor based on public scoping, review project project alternatives.
