Los Angeles County Supervisor Don Knabe announced plans today for a traffic signal synchronization project in the City of Diamond Bar. The total cost of the project is expected to be $700,600, with funding coming from several sources. Approximately $595,600 will come from the County, with $516,400 coming from the County’s Metropolitan Transportation Authority Grant Fund and $79,200 coming from other County funds. The remaining $105,000 will come from a contribution by the City of Diamond Bar.
The project involves equipment installations on Golden Springs Drive from Adel Avenue to Copley Drive and also along other portions of Copley Drive. Upgrades will also occur on Pathfinder Road from Brea Canyon Road to the State Route 57 southbound ramp, Brea Canyon Road from Golden Springs Drive to Washington Street, Diamond Bar Boulevard from Gentle Springs Drive/Palomino Drive to the State Route 60 eastbound ramp, and on Golden Springs Drive from Brea Canyon Road to the State Route 60 eastbound ramp.
This project is part of the County’s larger effort to install and administer Intelligent Transportation Systems (ITS) within various cities and unincorporated areas.
