In a sudden and alarming event, the Interstate 5 (I-5) Freeway near Castaic, California, was closed on Saturday due to a gas line explosion that led authorities to issue a shelter-in-place order.

The dramatic incident occurred at approximately 4:20 p.m. Pacific Time, when a 34-inch gas transmission line burst near Ridge Route Road and Pine Crest Place. Los Angeles County Fire Department officials later confirmed that the line was operating under a pressure of 600 psi. As of now, the cause of the explosion is still under investigation, according to reports from KTLA 5.

Residents in the vicinity described the explosion as deafening, likening it to the sound of a jet engine, and reported that the force was strong enough to cause their homes to tremble. Those living in nearby Granada Hills, Porter Ranch, and Sylmar reported a noticeable gas odor permeating the air around their neighborhoods.

In response, Los Angeles County Fire officials advised, “Seek shelter inside. Close all doors, windows, and vents. Shut off HVAC systems.”
