Public Transportation and Stations

Public transit is vital to Chicago’s way of life, and CDOT and CTA are partners in this system, sharing common goals and vision that ensures safe and efficient transit service while working together to solving transit problems.

CTA buses run on the streets CDOT builds, and CTA trains operate on a rail network that includes 50 miles of track and more than 50 stations built and owned by CDOT.  

CDOT focuses its work on planning, architectural and engineering projects, while passing funds onto the CTA for signals, power and other system needs.  In the last two years, CDOT completed a major reconstruction of the Grand/State Red Line Station and a new Morgan Station serving the Green and Pink Lines.  

The partnership also includes the design and construction of future Bus Rapid Transit facilities across Chicago, as well as the development of bicycle, pedestrian and other inter-modal facilities to provide access to transit or an alternative option to motor vehicle travel.

Better Streets for Buses

CDOT and the Chicago Transit Authority (CTA) are developing the Better Streets for Buses Plan to be the City’s first framework plan to improve street infrastructure for public bus service, and lay the groundwork for ongoing bus infrastructure improvements by establishing a network of corridors to prioritize and a toolbox of street treatments to consider as solutions. 

Thank you to everyone who provided comments on the Better Streets for Buses Plan, participated in a public meeting, or helped us spread the word about the public comment opportunity. We received thousands of comments from all over the city and are now reviewing them to inform revisions to the plan. If you would like to receive updates on the project, please send an email to Updates will also be posted here and on the project website,
