Castaic Gas Leak Forces 5 Freeway Shutdown

A natural gas leak from a major transmission line in Castaic on Saturday, December 27th, 2025, prompted a significant emergency response and hours-long closure of the 5 Freeway. The rupture occurred near the intersection of Ridge Route Road and Pine Crest Place, releasing gas from a 34-inch pipe under extreme pressure. This forceful release caused public safety concerns and a strong odor detected miles away in areas like Santa Clarita.

The incident led to the shutdown of the 5 Freeway in both directions, causing considerable traffic disruptions during one of the year's busiest travel periods, just days after Christmas. Firefighters, hazmat teams, and emergency command posts were deployed to the scene as a precaution. Despite the dramatic nature of the leak and some initial public concern about potential explosions, officials confirmed no explosion occurred and no injuries were reported.

As of Sunday, December 28th, 2025, the gas has been shut off, and officials stated the immediate danger to the public has passed. However, a shelter-in-place order continues for the immediate vicinity, including Charley Canyon, Hillcrest, and Wayside, while crews work on permanent repairs. The smell of natural gas is expected to continue fading as the situation is resolved.
