The California Department of Transportation (Caltrans) proposes repairing and replacing electrical equipment near the City of Lodi, on State Route (SR) 12, from post mile 16.65 to 19.00, in San Joaquin County. The scope of work includes replacing backplates, traffic detector loops, and group re-lamps. All work will occur within existing Caltrans Right of Way. The purpose of this project is to upgrade the existing electrical equipment, which is damaged or outdated. The project is needed to improve traffic communications and safety for the traveling public on SR-12.
