CTA will rebuild four (4) of the oldest Red Line Stations: Lawrence, Argyle, Berwyn, and Bryn Mawr, thus making them accessible to people with disabilities. In addition, CTA will construct a rail bypass to replace a 100-year-old junction north of the Belmont station to improve train operations and add train capacity to facilitate commuter travel for our customers on the Red, Purple, and Brown Line trains during 2017-2018 and estimated to last 4-5 years to be completed in the mid 2020s.
