CTA Red-Purple Line alternative: Basic Rehabilitation with Transfer Stations

Basic Rehab with Transfer Stations Alternative.JPG

This alternative includes all of the elements of the Basic Rehabilitation Alternative plus new transfer stations at Wilson and Loyola.

Estimated cost
$2.9 billion

Longevity
20 years (60-80 years at new transfer stations)

Evanston Branch
Same as Basic Rehabilitation Alternative in this segment for this alternative.

North Red Line

In addition to including all of the elements of the Basic Rehabilitation Alternative, this
alternative adds new transfer stations at Wilson and Loyola in this segment.

The existing embankment structure would be replaced with a modern concrete aerial structure along the one mile of associated structures at the new transfer stations. Current embankment structures would be maintained and upgraded in all other areas.

The new transfer stations and one mile of associated structures would have a useful life of 60-80 years; the rest of the improvements would have a useful life of 20 years.

Additional access to express service would be possible at the two new transfer stations. This alternative would allow for potential expanded hours of express service.
