The Chicago Department of Transportation’s responsibility is to keep the city’s surface transportation networks and public way safe for users, environmentally sustainable, in a state of good repair and attractive, so that its diverse residents, businesses and guests all enjoy a variety of quality transportation options, regardless of ability or destination.

CDOT’s vision is to ensure that Chicago continues to be a vibrant international city, successfully competing in the global economy with a transportation system that provides high-quality service to residents, businesses, and visitors – a system that offers a solid foundation for the local, regional and national economies, yet is sensitive to its communities and environment.
