A major California freeway was closed on Saturday after the U.S. Marines conducted a live-fire event, disrupting traffic along the 5 Freeway for approximately four hours. The closure, which affected travelers between Harbor Drive and Basilone Road, began at 11 a.m. Pacific Time and lasted until around 3 p.m., according to the California Highway Patrol.
The event, held at Camp Pendleton in northern San Diego County, coincided with Vice President JD Vance’s visit, where he delivered a speech honoring the U.S. Marine Corps’ 250th anniversary. Vance, a Marine Corps veteran, praised the service branch’s history and legacy but did not address the freeway closure during his remarks. He highlighted the Marines’ role in global conflicts, from World War II to recent operations, and credited his military experience with shaping his career.
The exercise included a demonstration of amphibious combat tactics, with Marines simulating beach landings to showcase their capabilities. Vance also criticized efforts to prioritize “diversity quotas” over military readiness, stating that such policies hinder the Corps’ effectiveness. His comments came amid broader debates about the direction of U.S. military strategy under the Trump administration.
The 5 Freeway, a critical route connecting San Diego and Orange counties, sees roughly 80,000 vehicles daily. While initial plans called for a full closure, southbound lanes were reopened by noon. The event underscored the intersection of military training, public infrastructure, and political symbolism in Southern California.
