An afternoon fire along northbound Interstate 5 near Templin Highway in Castaic quickly jumped from a burning semi‑truck into nearby brush, prompting an evacuation warning for a mobile‑home park, authorities said. Thick smoke and flames loomed over the freeway as Los Angeles County and U.S. Forest Service crews rushed the hillside to keep the blaze from reaching homes. Northbound lanes of the busy I‑5 were partially shut down while firefighters attacked the flames.
Crash Sparks Brush Fire, Officials Say
According to CBS News Los Angeles, the Los Angeles County Fire Department reported that a semi‑truck hauling cars crashed and caught fire, and the resulting blaze had grown to about 25 acres by 5:25 p.m. LACoFD crews worked alongside Angeles National Forest personnel as officials issued an evacuation warning for residents downwind of the flames.
Evacuation Warning For Paradise Ranch Estates
Officials with the Angeles National Forest put an evacuation warning in place for the Paradise Ranch Estates mobile‑home community on Templin Highway near the freeway, ABC7 reported. Crews positioned engines and other equipment near the park while telling residents to be ready to leave if the fire pushed closer.
Traffic Impacts On I‑5
Caltrans told news outlets that the three right lanes of northbound I‑5 were closed while firefighters worked the scene, backing up traffic along the corridor, according to CBS News Los Angeles. Authorities issued a SigAlert on the northbound side to free up space for emergency vehicles and cut down on the risk to drivers rolling through heavy smoke.
Why Fires Near I‑5 Can Move Fast
Castaic’s steep, dry hills and long track record of roadside fires make this stretch of freeway especially vulnerable to fast‑moving blazes that can threaten neighborhoods and shut down lanes in a hurry. The Los Angeles Times detailed how the 2022 Route fire in the same general area surged to more than 5,000 acres and forced evacuations, a reminder of how quickly conditions near the 5 Freeway can spiral.
How Residents Can Stay Informed
Officials urged residents to keep an eye on local alerts and follow directions from firefighters and law enforcement if conditions change.
