Emergency crews battled a massive brush fire that shut down the 5 Freeway in Sun Valley on Saturday night.

Officially named the Penrose Fire, the incident was escalated to “Major Emergency Status,” according to the Los Angeles Fire Department.

The small grass fire grew into a massive blaze fueled by heavy winds that ignited grass, trees and nearby vegetation. Thick smoke caused poor visibility on nearby roads.

Over 160 firefighters were dispatched to battle the fire that eventually grew to 2 acres.

Authorities shut down both northbound and southbound lanes of the 5 freeway between the Hollywood Freeway (SR-170) and Sunland Boulevard. All lanes have now reopened.

Crews were dispatched to the scene a little before 8 p.m. When they arrived, the flames had jumped from vegetation to at least two nearby buildings. One building contained combustible metals which officials say caused a hazmat situation.

Citizen photos show flames erupting into the night sky as fiery debris rained down around gridlocked traffic.

Drivers were asked to avoid the area as major delays were expected.

It took around two and a half hours to extinguish the flames. No injuries have been reported.

Fire risk remains high as the National Weather Service issued a Red Flag Warning for the weekend due to gusty Santa Ana winds and low humidity across Los Angeles and Ventura counties.
