The Illinois Department of Transportation will replace or upgrade dozens of traffic signals on state routes in older sections of Joliet in 2021.
The Joliet City Council this month approved city participation in the $2.2 million project.
Joliet will contribute $253,000, with most of the costs covered by the state. Construction is planned for the spring.
The project includes new traffic lights being installed at:
• Jefferson Street intersections at Center, Hickory, Joliet and Scott streets
• Cass Street intersections at Eastern Avenue, Scott Street and Joliet Street
• Western Avenue and Hickory Street
• Scott and Jackson streets
The new traffic signals systems will include LED-illuminated street signs that were requested by Joliet and will be paid for by the city.
Joliet also will pay for Emergency Vehicle Preemption devices used to stop traffic when ambulances and police cars approach the intersection.
IDOT will cover 90% of the remaining costs.
An additional 39 traffic signals will be upgraded at intersections along Routes 6, 30, 52 and 53.
The upgrades will be installations of retroflective backplates to the traffic lights such as are seen at newer intersections on the far West Side, Joliet Public Works Director James Trizna said. The yellow backplates installed behind the traffic lights are designed to improve visibility, he said.
The upgrades are at intersections in the near East and West sides.
City funds for the project will come from the Motor Fuel Tax Fund.
