The upcoming closure of Interstate 5 near Camp Pendleton in Southern California is set to cause significant disruptions for commuters and travelers alike. Here's a detailed breakdown of what you need to know and how to plan your journey during this closure.
Understanding the Closure
- When: The closure is scheduled to take place from 11 a.m. to 3 p.m. on Saturday, October 18, 2025.

- Los Angeles County to San Diego County: Head east on Route 91 through Corona, then take Interstate 15 south to reach San Diego County.

Rail Service Disruptions
Amtrak Pacific Surfliner and Metrolink services are also expected to be affected by the closure, so rail commuters should plan alternative routes accordingly.
The Impact on Commuters
The closure will significantly increase travel times, turning a usually 22-mile, 23-minute drive from Oceanside to San Clemente into a 138-mile, 2-hour-and-20-minute journey if drivers attempt to avoid Orange County's toll roads and detour around Camp Pendleton. This highlights the importance of planning ahead and considering alternative routes.
