Firefighters contained a vegetation fire on Altamont Pass in far eastern Alameda County Saturday night to less than two acres, Cal Fire reported in social media.
The fire was started shortly after 8:30 p.m. Saturday, the California Highway Patrol said, when a car was forced off of eastbound Interstate 580 near the North Flynn Road interchange by a big rig.
The car rolled up an embankment and caught fire, which in turn ignited dry vegetation, Cal Fire said.
The fire, fought by Cal Fire, the Alameda County Fire Department and the Livermore-Pleasanton Fire Department, was contained by 9:15 p.m. Saturday. No one, including the car driver, was injured.
Eastbound traffic on I-580 continued to move slowly through the area, with the two right lanes closed until after 9 p.m.
Meanwhile, a brush fire not far away, southwest of Tracy, was fully contained at 283 acres, Cal Fire said Friday morning.
The blaze, first reported on Wednesday afternoon, burned grass and vegetation off West Corral Hollow Road in the Carnegie State Vehicular Recreational Area in San Joaquin County.
Cal Fire said on social media Friday that firefighters will be patrolling the area for the next few days.
No injuries were reported in the blaze and no structures were damaged.
The cause is under investigation.
