Oct. 18 (UPI) — The U.S. Marine Corps‘ live-fire event at Camp Pendleton as part of its 250th birthday celebration will cause the closure of Interstate 5 for four hours on Saturday.

The closure is a precaution due to the firing of explosive artillery rounds over the freeway from gunnery ranges at Camp Pendleton in Southern California, which has drawn the ire of California Gov. Gavin Newsom.

Newsom accused President Donald Trump of “putting his ego over responsibility with this disregard for public safety” in a prepared statement released on Saturday morning.

“Firing live rounds over a busy highway isn’t just wrong — it’s dangerous,” Newsom said.

“Using our military to intimidate people you disagree with isn’t strength,” he added. “It’s reckless. It’s disrespectful, and it’s beneath the office he holds.”

Trump will not attend the celebratory event, but Vice President JD Vance and Defense Secretary Pete Hegseth are scheduled to attend, with the live-fire scheduled at 1:30 p.m. local time.

Marine Corps officials initially said there would be no need to close the freeway and only asked that signs be posted warning drivers of the live-fire event and to expect to hear explosions.

California Highway Patrol officials instead announced the freeway would be closed while the event is in progress, according to KTLA-TV.

Due to safety concerns, a section of Interstate 5 will be closed Saturday due to a White House-directed military event at Camp Pendleton involving live ammunition being discharged over the freeway,” Caltrans officials said in a statement on Saturday morning.

“Drivers should expect delays on Interstate 5 and other state routes throughout Southern California before, during and after the event.”

The closure starts at 11 a.m. PDT for the 17-mile stretch of freeway running from Basilone Road near San Onofre in the north to Harbor Drive in Oceanside to the south and reopens at 3 p.m.

The event will include a demonstration of Navy and Marine Corps operations on land, sea and in the air.

Camp Pendleton is located about 40 miles north of San Diego and east of I-5, which runs along the Pacific Coast.

Caltrans officials advise motorists in Los Angeles County to use state routes in San Diego, Los Angeles, Orange and Riverside counties to bypass the closed section of freeway.

Several local train routes also will be closed during the live-fire event.

SACRAMENTO  — Gov. Gavin Newsom’s office is weighing whether to close parts of Interstate 5 beginning Friday amid concerns over what it says is a White House-directed plan to use live ordnance during a military anniversary celebration off Camp Pendleton’s coast in San Diego County — where Navy ships are expected to fire over the freeway onto the base.

Newsom’s office has received, but not confirmed, reports that live ordnance will be fired from offshore vessels during the event commemorating the Marine Corps’ 250th anniversary. The event is titled “Sea to Shore — A Review of Amphibious Strength” and will feature Vice President JD Vance.

Newsom’s office said it has received little information about the event or safety plans. The military show of force coincides with No Kings rallies and marches across the state on Saturday that are expected to draw large crowds, demonstrations challenging Trump and what critics say is government overreach.

“Donald Trump and JD Vance think that shutting down the I-5 to shoot out missiles from ships is how you respect the military,” Newsom posted on the social media site X Wednesday.

A military media advisory said the celebration will include a live amphibious assault demonstration. The Times could not confirm whether live ordnance will be fired over the freeway. The White House and Marine Corps did not respond to questions from The Times.

“California always honors our Marines — but this isn’t the right way to go about it,” said a Newsom spokesperson. “The White House should focus on paying their military, lowering grocery prices and honoring these soldiers for their service instead of pompous displays of power. The lack of coordination and communication from the federal government on this event — and the overall impact to our society and economy — is evident of the larger disarray that is the Trump Administration.”

Freeway closures are being considered for a section of I-5 between Orange County to San Diego County from Friday to Saturday, which would cut off a major traffic artery that moves upward of 80,000 travelers a day. A closure with little notice would likely result in massive gridlock from Dana Point in the north to well past Del Mar in the south.

Vance, the first Marine veteran to serve as vice president, is expected to attend the event Saturday along with 15,000 Marines, Sailors, veterans and their families, according to event’s media release. Along with Vance, Defense Secretary Pete Hegseth is expected to deliver remarks.

Camp Pendleton advised nearby residents that there will be live-fire training with high explosive munitions through Sunday, which will result in some roads on base being closed.

The Trump administration previously had plans for a major celebration next month for the 250th anniversary of the Navy and Marines, which would have included an air and sea show — with the Blue Angels and parading warships — attended by President Trump, according to the San Diego Union-Tribune. Plans to host that show in San Diego have been called off, the paper reported.

Camp Pendleton is a 125,000-acre base in northwestern San Diego County that has been critical in preparing soldiers for amphibious missions since World War II thanks to its miles of beach and coastal hills. The U.S. Department of Defense is considering making a portion of the base available for development or lease.
