CASTAIC, Calif. (AP) — Firefighters fought to maintain the upper hand on a huge and rapidly moving wildfire that swept through rugged mountains north of Los Angeles and resulted in more than 50,000 people being put under evacuation orders or warnings.

It was first reported just after 11 p.m. near northbound lanes of the freeway in Sherman Oaks, according to the Los Angeles Fire Department.

A new fire broke out Wednesday night along the 405 Freeway. The fire was burning on the east side of the freeway near the Sepulveda Fire Road. Multiple fire engines were on the scene.
