The California Department of Transportation (Caltrans) advises motorists planning to travel on the northbound Golden State Freeway (I-5) in Castaic, located between the City of Santa Clarita (Valencia) and “The Grapevine,” to plan ahead and leave early to avoid holiday-related traffic delays. Heavy traffic is expected beginning Wednesday, December 20th through New Years Day.
An ongoing lane closure on northbound I-5 at Templin Highway will continue throughout this time for slope stabilization repairs. Three northbound lanes and all four southbound lanes will remain open.
