The North Red and Purple Lines Vision Study occurred from 2009 to 2010. This early public participation resulted in over 1,100 public comments that helped shape the Red and Purple Modernization project alternatives proposed for study in a Tier 1 Environmental Impact Statement.
The Red and Purple Modernization Project is currently going through the Public Scoping process.
The following information is provided as an archival reference...
The North Red and Purple Lines Vision study area extends approximately 9.5 miles, from north of Belmont station on the Red Line to Linden terminal on the Purple Line.
North Red and Purple Line Corridor (Addison to Linden) was substantially built in 1920’s
1.4 miles of elevated track
7.6 miles of retaining/ballasted track
Most stations are in deteriorated condition, have very narrow platforms and are not accessible
Bridges and retaining walls are deteriorated and costly shoring systems are required at locations to maintain service
Power and signal systems are at end of service life and create service reliability issues
Vision Study Objectives
In order to appropriately address the CTA’s crucial infrastructure needs, the agency will need to develop comprehensive plans for reconstructions. As such, this Vision Study will help to identify and evaluate concepts that would, at a minimum, bring the North Red and Purple Lines to a state of good repair and provide a modern sustainable service for the next century.
The objectives of the Vision Study are to:
Identify feasible options
Initiate Stakeholder Involvement
Identify preliminary environmental constraints
Establish evaluation criteria
Develop preliminary scope of work for selected few options
Develop program level costs for each detailed options
The study identifies program level cost, potential community impacts/benefits, environmental concerns and constructability issues for the CTA North Red and Purple Line corridors.
