Contra Costa County is investing $30.8 million to upgrade traffic signals at approximately 365 intersections across all 19 cities and unincorporated areas. - The project will modernize aging infrastructure with synchronized signals, emergency vehicle preemption, transit priority, and enhanced pedestrian/bicycle detection.
- Initial work begins in Danville and Concord, then expands countywide. - Funding comes from Measure J sales tax, local contributions, and over $7 million in federal transportation grants.
- Officials say the upgrades will improve traffic flow, safety, and emergency coordination during major events.
