Highway patrol announces last-minute, multihour closure due to military celebration including 155-mm artillery shells
A celebration marking the US marines’ 250th anniversary will shut down a major freeway artery through southern California on Saturday as the military plans to fire live 155mm artillery shells over the site.
The California highway patrol announced the closure at 6am Saturday, saying it would shut down an approximately 17-mile (27km) stretch of Interstate 5 for four hours near Camp Pendleton, a 125,000-acre (50,585-hectare) base in Oceanside in north-western San Diego county. The closure will remain in effect from 11am to 3pm.
The event in question will include a live-fire amphibious capabilities demonstration at Red Beach, according to a statement from the US marine corps. JD Vance, a former enlisted marine who served in Iraq, is scheduled to speak to at least 15,000 marines, sailors, veterans and families expected to attend. Defense secretary Pete Hegseth will also deliver remarks.
“The capabilities demonstration will feature integrated Navy and Marine Corps operations across air, land and sea,” the Marines’ statement said.
