A reported leak from a rupture in a gas line in northern Los Angeles County led authorities to urge nearby residents to stay inside and to temporarily shut down a major Southern California highway for several hours on Saturday, snarling traffic for miles.聽

The 34-inch gas main line is located just east of the southbound lanes of Interstate 5 in Castaic, a major thoroughfare linking Southern and Northern California.聽

Capt. Brian Kight, a spokesman for the L.A. County Fire Department (LACFD), said the call for the leak came in around 4:20 p.m. local time. Kight said there were no reports of any explosions from the leak and no reported injuries.聽

A shelter-in-place order, impacting 14,900 people, was lifted earlier Sunday, according to the LACFD.

Authorities said that there is no danger to the public.

"Some residents may smell an odor of natural gas in the air -- please note this is not harmful and poses no immediate danger to residents," the LACFD said in its statement Sunday.
