After years of doing whatever they were doing, the CTA has released details of its planned Red and Purple Line renovations north of Belmont:
We already know the first phase of the project, set to begin in 2017, will involve rehabbing the Lawrence, Argyle, Berwyn and Bryn Mawr Red Line stations and replacing tracks for the Red and Purple Lines at those stations to reduce slow zones. CTA has started the process of securing federal funding to extend the Red Line from its current southern endpoint at 95th Street to 130th Street, using existing freight rail tracks. That project would cost $2.3 billion.
The aspect of the Red/Purple Line rehab we’re most impressed by is a “Belmont bypass” allowing the Brown Line to continue along its route by riding above the existing Red and Purple Line rails. Currently the Brown Line has to negotiate its route by crossing those rails, resulting in 40 percent of weekday trains being delayed by up to three minutes.
In order for the bypass to be built CTA will have to buy 16 buildings between Belmont Avenue and Addison Street in order to make room for the project. The total cost of the Belmont bypass is included in the $1.7 billion cost the first phase of Red and Purple Line rehab is expected to cost.
The CTA says the bypass project will save 500,000 passenger-hours per year.
