I-5 Shut Down Amid Military Demonstration Sparks Political Backlash

CAMP PENDLETON NORTH, Calif. — A major section of Interstate 5 was closed on October 18 for a military demonstration involving live ammunition, creating significant traffic disruptions in Southern California. The California Highway Patrol reported that the closure ran from Harbor Drive to Basilone Road, impacting over 15 miles of the busy freeway from 11 a.m. to 3 p.m. local time.

The demonstration was coordinated with the attendance of Vice President J.D. Vance and Secretary of War Pete Hegseth at Camp Pendleton. As controversies swirled between California Governor Gavin Newsom and federal officials, tensions escalated regarding safety protocols around the event.

Capt. Gregory Dreibelbis, Current Operations Officer for the I Marine Expeditionary Force, noted that despite concerns raised, no roads were officially requested to close for the military exercise. ‘The Navy-Marine Corps team coordinated closely with state agencies to ensure the demonstration could proceed safely,’ Dreibelbis stated in an email to USA TODAY.

Representatives from the Marines initially claimed that the exercise would be held entirely on approved training ranges with safety measures firmly in place. However, in a surprising turn, officials later deemed it necessary to shut down the freeway due to ‘extreme life safety risks’ posed by the live demonstrations.

The governor expressed his disapproval of the situation, labeling it an ‘absurd show of force’ and criticizing the irresponsible use of military practices. ‘Firing live rounds over a busy highway isn’t just wrong – it’s dangerous,’ Newsom stated, adding that it was a distraction that put drivers at risk.

Moreover, the closure not only affected freeway traffic but also disrupted adjacent rail services running between San Diego and Los Angeles. Caltrans advised motorists to expect delays leading up to, during, and after the event.

As the demonstrations showcased Marine capabilities, including live fire and amphibious operations, politicians from both sides voiced their concerns. California Rep. Mike Levin emphasized that public safety and the Marine Corps’ reputation should be prioritized over political agendas.

In a shared sentiment, San Diego County Supervisor Jim Desmond criticized the lack of cooperation from state and federal officials, stating that the incident reflected poorly on the political environment. ‘No accountability, no planning — just finger-pointing while everyday people sit in traffic,’ he said.

Despite the backlash, the demonstration went on, culminating in a record of enhanced military readiness contrasting sharply with public discontent. Federal officials emphasized that thorough risk assessments were conducted in preparation for the live-fire event.

As the situation unfolded, the freeway was reopened shortly after 3 p.m. The incident continues to spark discussions on military training practices and public safety concerns during such events.
