I-5 Freeway Temporarily Closed for Marine Corps Live-Fire Event at Camp Pendleton

A 17-mile section of Interstate 5 in Southern California was temporarily closed on Saturday due to a live-fire military demonstration at Camp Pendleton, commemorating the U.S. Marine Corps' 250th anniversary. The closure, affecting both directions from Harbor Drive in Oceanside to Basilone Road near San Onofre, began at 11 a.m. and lasted until approximately 3 p.m., leading to substantial traffic congestion in the area.

The California Highway Patrol (CHP) announced the closure, citing safety concerns associated with live ammunition being discharged over the freeway. The CHP advised motorists to expect delays and consider alternative routes during the event. Additionally, Amtrak services between Orange and San Diego counties were suspended during the closure period.

Governor Gavin Newsom criticized the federal government's handling of the event, stating, "The President is putting his ego over responsibility with this disregard for public safety. Firing live rounds over a busy highway isn't just wrong — it's dangerous." He emphasized the potential risks and disruptions caused by the demonstration.

The Marine Corps' anniversary event featured an amphibious capabilities demonstration attended by Vice President JD Vance and Secretary of Defense Pete Hegseth. Despite initial assurances that no public highways would be closed, the decision to shut down the freeway was made to ensure public safety during the live-fire exercises.

Interstate 5 is a critical transportation corridor, accommodating over 80,000 travelers and facilitating $94 million in freight daily. The unexpected closure underscored the challenges of balancing military commemorations with public safety and transportation needs.
