Red Ahead: Red & Purple Modernization

Outreach and events

Granville track construction

To prepare for new track and station construction starting in 2021, we're improving our Red and Purple Line track structures now so we can continue to provide service to our customers during construction. Recently, we held a briefing with residents near the Red Line and Granville to provide an update on the work.

Virtual town halls 

CTA's RPM team held out first virtual community meetings. While we always prefer to talk face-to-face with local residents, we're grateful to continue to engage with everyone in a safe, informational way.

Your voice matters!

We strive each day to keep residents, businesses and CTA riders informed about all matters regarding the Red-Purple Modernization (RM) Phase One Project, from utility relocation work and street and alley closures to how the structure is going to look when the project is done.

We want to keep an open dialogue with you the community. This page provides updates on upcoming and past outreach events along with tools on how to receive the latest information.
