How to get around the Interstate 5 closure through Camp Pendleton in Southern California

"Interstate 5 from San Clemente to Oceanside has long been one of California's traffic choke points, with no other nearby alternative routes between Los Angeles and San Diego. So traffic delays could be significant Saturday with the U.S. military planning to fire live artillery rounds over Interstate 5 in Southern California. The freeway will be shut down temporarily Saturday afternoon along a 17-mile stretch of coastal northern San Diego County, just south of the border with Orange County."

"It'll affect the portion of Interstate 5 alongside Marine Corps Base Camp Pendleton, which is one of the military's busiest installations. The closure will sever the primary link between the southern coastal edge of Orange County and the northern beach cities of San Diego County. Motorists will be forced to drive all the way around the mountainous Camp Pendleton - which spans 125,000 acres - utilizing Interstate 15 as the primary alternate route."

Interstate 5 will close Saturday from 11 a.m. to 3 p.m. while live U.S. military artillery rounds are fired over the freeway under White House direction. The temporary shutdown covers a 17-mile coastal stretch alongside Marine Corps Base Camp Pendleton, between Basilone Drive south of San Clemente and Harbor Drive north of Oceanside. The closure severs the primary coastal link between Orange County and northern San Diego beach cities, forcing motorists to detour around the 125,000-acre base primarily via Interstate 15 and substantially increasing travel time and distance. Amtrak Pacific Surfliner and Metrolink rail service will also be disrupted.
