Chicago Department of Transportation

Chicago's Department of Transportation provides information about public-way infrastructure, streets, bridges, traffic safety, pedestrian and cycling resources, and transportation projects. Its website serves residents, visitors, businesses, and professionals using city infrastructure.

The actual location and work determine permits, restrictions, and project procedures. The department is separate from CTA and other transit operators. A public map or proposed project should not be treated as permission to carry out work or as a guarantee of current road conditions.
