A traffic incident on Thursday, May 7, 2026, caused a temporary closure of the Main Gate (Miramar Way) at Marine Corps Air Station (MCAS) Miramar.
Incident Summary
Location: The closure specifically affected the East Gate (Main Gate), which provides primary access to the base from Interstate 15.
Cause: According to base officials and local traffic reports, a multi-vehicle collision occurred near the inbound inspection lanes during the late afternoon commute. The incident required emergency vehicles to block all inbound lanes for approximately one hour.
Current Status: As of 5:30 p.m., the Main Gate has reopened, though military police are still managing residual heavy traffic. Drivers are advised to expect delays or use alternate entry points.
Alternate Access Points
While the Main Gate is back in operation, the following gates were utilized to divert traffic during the closure:
North Gate (Miramar Road): Remains open for standard housing and personnel access until 10:00 p.m.
West Gate (Miramar Road): Typically closed during these hours, the West Gate (closest to I-805) was briefly opened to outbound traffic only to help clear the base.
Safety Reminders
Base security reminds all personnel and visitors that the five-mile stretch of the I-15 near Miramar Way is one of the most high-traffic areas in San Diego County. Commuters are encouraged to:
Maintain the posted speed limit of 25 MPH immediately upon entering base property.
Avoid “lane splitting” on motorcycles when approaching gate security.
