File a Transportation FOIA Request
The Freedom of Information Act (FOIA) is a state law that provides citizens with access to public records. Each City department is a separate agency responsible for maintaining its own records, so requests should be submitted to the department that maintains the records you want.
All Freedom of Information requests submitted to City of Chicago departments must include the following information:
- The name, mailing address and contact information of the requester;
- A description of the records that are being requested.
If you are seeking records about CDOT or its projects or programs, your request must be in writing. Please be specific about the information you are seeking, and indicate exact locations and dates whenever possible. This includes information such as:
- When a permanent metal street sign was installed
- What public construction occurred in a given area
- A street lane configuration or pavement markings
Red Light Camera Video Requests
24-hour streaming video from red-light cameras is available for review for 30 days. Video of red-light violations are available for review for a period of two years.
