A 17-mile stretch of Southern California’s Interstate 5 (I-5) is going dark for a few hours this weekend, due to live gunfire. According to ABC7, the California Highway Patrol (CHP) confirmed the closure, which will run from Harbor Drive in Oceanside to Basilone Road near San Onofre, from 11 am to 3 pm local time on Saturday.

The reason: a US Marine Corps demonstration using live ammunition to mark the branch’s 250th anniversary at Camp Pendleton. Officials said rounds will be discharged “over the freeway,” prompting the temporary shutdown for safety.

Massive traffic delays, train cancellations expected

The event’s impact goes far beyond cars. ABC7 reports that Amtrak service between Orange and San Diego counties will be suspended during the closure, leaving no rail options for travelers in the area.

The decision to go forward with live fire near the I-5 came after a week of mixed messaging. Earlier, Marine officials had claimed the freeway would remain open. But late Friday, Governor Gavin Newsom’s office said federal authorities had confirmed that live artillery fire was planned for Saturday afternoon.

The freeway is scheduled to reopen by 3 pm, once the live-fire exercise wraps up.
