A brush fire along Interstate 5 near HWY 138 temporarily closed down all lanes along northbound I-5 Tuesday afternoon.
Firefighters were using three helicopters and a plane to bombard the brush fire burning adjacent to Interstate 5 freeway.
Los Angeles County Fire Inspector Joey Marron says the blaze broke out shortly after 1 p.m. in the Gorman area and burned across 40 acres by mid-afternoon.
No structures were threatened but heavy smoke briefly closed a section of the freeway that connects Los Angeles to San Francisco through Kern County.
No estimated time of containment was available, but Marron says winds in the area were only of moderate speed.
Kern County firefighters were called out to the fire at about 2 p.m. and closed down all NB lanes into Kern County as they fought the fire.
At about 3 p.m., crews opened up all but one lane as they continued to fight the fire.
Los Angeles County Fire Department said that the fire has grown to 60 acres and is at 80% containment as of 3:30 p.m.
