Overview
- A high-pressure transmission pipeline ruptured about 4:20 p.m. Saturday near Ridge Route Road and Pine Crest Place beside the southbound I-5 in Castaic.
- CHP issued a SigAlert and closed both directions of I-5 with detours to SR-126 and SR-138 before reopening the freeway around 8:45–9 p.m.
- A shelter-in-place affecting roughly 14,900 residents in nearby neighborhoods was lifted around 10 p.m., and no evacuations were ordered.
- SoCalGas isolated the damaged section and stopped the leak, with hazmat teams conducting atmospheric monitoring and officials reporting no ignition or explosion.
- Repair planning is underway, a few nonresidential customers experienced service interruptions, and residents may still notice gas odors as remaining gas dissipates.
