# Chicago Transit Authority Red Line Extension

![Chicago Transit Authority Red Line Extension](https://www.systra.com/usa/wp-content/uploads/sites/6/2024/08/istock-889547640-scaled.jpg)

The Red Line Extension Program is the largest project in CTA history. It will
provide faster connections from the Far South Side to the rest of the city while
serving as an economic catalyst to one of the most disinvested parts of Chicago.
SYSTRA, in a joint venture as the lead designer for the Walsh-VINCI Transit
Community Partners, is responsible for the design of a wide range of systems,
including structural, track, signals, communications, power, and electrical. 
Our role also encompasses systems integration and validation.

The project will add four new fully accessible stations, which will feature
multimodal connections at each station. The 96^(th) Street interlocking will
enable trains to move from the existing Red Line mainline to 98^(th) Street yard
and shop and new Red Line mainline.
