California Considers I-5 Closure Amid Camp Pendleton Live-Fire Event Concerns

Governor Gavin Newsom's office is evaluating the potential closure of sections of Interstate 5 starting Friday, citing safety concerns over a planned live-fire military demonstration at Camp Pendleton in San Diego County. The event, titled "Sea to Shore — A Review of Amphibious Strength," commemorates the Marine Corps' 250th anniversary and is expected to feature live ordnance fired from Navy ships offshore toward the base.

Newsom's office has received reports about the use of live ordnance during the event but has not confirmed these details. The governor expressed frustration over the lack of communication from federal authorities regarding safety measures and potential impacts on the community.

The California Department of Transportation (Caltrans) is preparing for possible freeway closures between Orange and San Diego counties, a stretch that accommodates over 80,000 daily travelers. Edward Barrera, a Caltrans spokesperson, stated that the agency is acting based on "potential scenarios shared with us by the federal government" and warned of significant traffic delays if closures are implemented.

Vice President JD Vance and Defense Secretary Pete Hegseth are scheduled to attend the event, which anticipates drawing 15,000 Marines, sailors, veterans, and their families. Camp Pendleton has advised nearby residents of live-fire training with high-explosive munitions through Sunday, resulting in some road closures on the base.

The White House and Marine Corps have not responded to inquiries regarding the event's specifics and safety protocols. The situation remains fluid as state officials await further information from federal authorities.
