CTA Red-Purple Line alternative: Basic Rehabilitation

Basic Rehab Alternative.JPG

This alternative includes a strategic mix of repairs, rehabilitation, and replacement to bring Evanston Branch and the North Red Line into a state of good repair. It would provide adequate service for the next 20 years. The stations, viaducts, and other structural elements would not be brought up to modern standards and would only meet minimal ADA requirements. Upgrades would be made to signals and communication systems.

Estimated cost
$2.4 billion

Longevity
20 years

Evanston Branch
Only one station would be renovated to accommodate 8-car trains; all others would receive minor or major repairs in order to accommodate ADA requirements. This alternative consists of upgrades to existing structures primarily within the existing CTA right-of-way and maintenance of the existing overall track alignment and station configurations. The current sloped embankment structure would be maintained with repairs and viaduct replacement as required.

North Red Line
Five stations would be fully renovated; all others would receive minor or major repairs in order to accommodate ADA requirements.

This alternative consists of upgrades to existing structures primarily within the existing CTA right-of-way and maintaining the existing overall track alignment and station configurations. Current embankment structures would be maintained and upgraded.

Express service with no stops between Howard and Belmont would continue to be provided in both directions during peak periods.

Pros
Maintains all current station stops.
Lowest price

Cons
Would only last 20 years
