Story developing — confirmed facts and preliminary information are separated below.
An I-5 Grapevine accident today has California Highway Patrol and Caltrans working to clear lanes on the Tejon Pass corridor, the critical 4,160-foot mountain crossing that connects the San Joaquin Valley to the Los Angeles basin. The Grapevine stretch of I-5 is one of the most crash-prone freeway segments in California, with weather, grade, and congestion combining to produce frequent multi-vehicle collisions.
Corridor Context
The Grapevine is the common name for the 40-mile stretch of Interstate 5 that climbs the Tehachapi Mountains between the San Joaquin Valley floor near Bakersfield and the Santa Clarita Valley north of Los Angeles. The corridor reaches its highest point at the Tejon Pass, elevation 4,160 feet, where winter storms can produce snow and ice while summer brings high heat and wind. CHP’s Fort Tejon office is the lead law enforcement agency for the corridor.
Recent Incidents
The CHP Fort Tejon Facebook page has documented multiple I-5 Grapevine accidents in 2026. On June 19, 2026, at 2:20 p.m., CHP reported all northbound lanes reopened south of Grapevine Road after an earlier accident, with traffic still congested through the area. The CHP Fort Tejon X account confirmed the #3 and #4 lanes were closed for road clean-up following that incident. Bakersfield Now reported on July 3, 2026, that all southbound I-5 lanes were closed north of Lebec due to a multi-vehicle crash, with lanes reopening by 2:34 p.m.
Lane Closure History
The Grapevine has a long history of weather- and crash-related closures. KTLA documented multiple crashes and icy road conditions that shut down portions of northbound I-5 through the Grapevine early on a Wednesday, stranding travelers and requiring CHP escorts once the road reopened. An Instagram post from CHP Fort Tejon confirmed all lanes reopened on southbound I-5 north of Fort Tejon Road at 9:15 p.m. after a #4 lane closure for vehicle fire clean-up. The Caltrans QuickMap page for I-5, last updated Friday, July 10, 2026, at 6:45 p.m., is the official source for current road conditions.
