What We Do

Traffic Safety, Signals, Lights and Signs

CDOT oversees all traffic signals, street, alley and viaduct lights, and is responsible for the installation and maintenance of all street signs.  

The Division of Electrical Operations maintains nearly 300,000 street and alley lights and more than 3,000 signalized traffic intersections.  They also handle other high-priority and emergency requests, like downed power wires and damaged or fallen poles.

Each year, CDOT handles tens of thousands of reports from Chicagoans about street and alley lights out.  Most of them are completed within a few days to a week.  CDOT prioritizes all-block outages before addressing single streetlight and alley light outages.

Streetlight repairs are done equally across the entire city.  No one area is prioritized over another. CDOT takes streetlight issues seriously, and uses many resources to provide repairs as quickly as possible.  We encourage citizens to continue to call 311 to report streetlight issues.
