Navigating I-5 Closure at Camp Pendleton, Southern California

Interstate 5 is a critical route in Southern California, linking San Diego and Los Angeles. However, this stretch has faced significant disruptions due to military activities, particularly around Camp Pendleton.
Navigating I-5 Closure at Camp Pendleton
This weekend, a planned military exercise required a temporary closure of a 17-mile section of I-5. The closure, which affected northern San Diego County, began at 11 a.m. and lasted until 3 p.m.
Closure Details
The California Highway Patrol reported the reopening of I-5 around noon. Despite the reopening, motorists were warned of a traffic break scheduled during the live artillery firing at 1:30 p.m. This event, directed by the White House, required the closure of I-5 near Marine Corps Base Camp Pendleton, a significant military installation.
Impact on Traffic
This closure disrupts essential travel routes and affects movement between Orange County and northern San Diego County. Motorists must detour around the base, a distance of approximately 125,000 acres.
- The drive from Oceanside to San Clemente could extend from 22 miles and 23 minutes to 138 miles and over 2 hours.
- This detour is necessary to avoid heavy traffic and the toll roads of Orange County.
- Traffic on I-5 often experiences delays, even on weekends.
Alternate Routes
To navigate around the I-5 closure, consider the following alternative routes:
- From San Diego to Los Angeles: Take Interstate 15 north, continuing through Temecula and Lake Elsinore, then Route 91 west.
- From Los Angeles to San Diego: Use Route 91 east to Interstate 15 south.
- From Orange County to San Diego: Head north on Route 55 to Route 91 east, then take Interstate 15 south.
- From San Diego to Orange County: Drive north on Interstate 15, then switch to Route 91 west and Route 55 south.
Additional Service Disruptions
In addition to road travel delays, rail services are also impacted. This affects both the Amtrak Pacific Surfliner and Metrolink services, further complicating transportation options for the affected areas.
The military’s live firing exercises underline the importance of preparation when traveling through this densely packed corridor. Travelers are encouraged to plan ahead and utilize alternative routes to avoid delays during such military events.
