Chicago is undertaking one of the largest street lighting modernization programs in the country.
Providing better quality, more reliable outdoor lighting for Chicago
The City of Chicago is installing better quality, more reliable LED light fixtures on streets, alleys and viaducts to increase safety, reduce energy costs and improve the environment.
The city-wide lighting initiative will replace over 270,000 existing outdated High Pressure Sodium (HPS) light fixtures with new energy-efficient LED lights and create a modern lighting management system to streamline maintenance and repairs.
