Fall 2024 TRAFFIC ALERT: Alameda County Public Works Agency’s paving operations for the Crow Canyon Road Pavement Repairs Project will begin Monday, September 25th. This Project will improve Crow Canyon Road by adding a new pavement overlay, new AC dike, and base repairs. Project completion is anticipated by mid-October.

During construction there will be major disruption to traffic with lane closures, traffic control, reduced speed limit, and traffic delays. The construction will be phased, beginning with work and lane closures on the westbound lane then shifting work onto the eastbound lane. Due to the constraints at this location, there will be at least one lane open on Crow Canyon Road depending on the type of work occurring at the time. Detours will also be implemented, where necessary.

Construction hours will be Monday – Friday, 8:00 AM to 5:00 PM. Access to all streets and driveways will be maintained. Residents, commuters, and businesses are encouraged to use alternate routes such as Norris Canyon Road, I-580, or I-680 during construction to minimize travel delays.
