The Golden State (5) Freeway in Castaic fully reopened Saturday night after a nearly five-hour closure due to a ruptured natural gas line. The incident caused significant traffic disruption, prompting a large-scale response from fire and gas crews.
Gas Line Rupture Disrupts Travel
The Los Angeles County Fire Department confirmed a natural gas leak in the area of Ridge Route Road and Pine Crest Place around 4:15 p.m. Multiple reports indicated that residents heard loud booms between 4:15 p.m. and 5 p.m., accompanied by a strong odor of natural gas. The ruptured line was identified as a 36-inch transmission gas line.
The California Highway Patrol closed all lanes of the 5 Freeway in both directions around 4:30 p.m., diverting northbound traffic to State Route 126 and southbound traffic to State Route 138. Motorists experienced substantial delays, with at least one driver reporting a 90-minute standstill before being redirected onto a fire road to rejoin the freeway.
Authorities worked to assist stranded motorists as the situation unfolded. The California Office of Emergency Services (Cal OES) stated the situation was “very dynamic” and urged the public to heed the instructions of local authorities.
The Los Angeles City Fire Department received reports of a natural gas odor from residents in Granada Hills, Porter Ranch, and Sylmar, but indicated no immediate danger to those communities. Governor Gavin Newsom was informed of the rupture and kept apprised of developments, according to his press office.
The freeway fully reopened shortly before 9 p.m., as announced by the CHP via social media.
