A brush fire triggered by a burning car blackened about 100 acres northwest of Corona Tuesday and prompted the partial closure of a highway before crews halted its spread.
The fire was reported shortly after 2 p.m. along the northbound Corona (71) Expressway, north of the junction with the Riverside (91) Freeway, according to the California Highway Patrol.
Officials said a white sedan caught fire, possibly from overheating, and the vehicle was quickly engulfed.
Flames jumped from the car to dry vegetation nearby, culminating in a wildland blaze that prompted the CHP to shut down all northbound lanes going into San Bernardino County.
No homes or other structures were immediately threatened. One firefighter was evaluated at the scene for an unspecified, non-life-threatening injury, according to Riverside County Fire Department spokeswoman Tawny Cabral. It was unclear if the firefighter required hospital care.
Corona Fire Department crews initially responded to the location, but the Riverside County Fire Department took over the battle because the flames were situated in an unincorporated area along the boundary separating Riverside and San Bernardino counties, according to reports from the scene.
Seventeen engine crews and five hand crews, numbering about 140 personnel, deployed to the wildfire. According to county officials, four air tankers and two water-dropping helicopters were making runs on the flames.
Ontario Fire Department personnel were assisting in attempting to encircle the brusher, which was not in the vicinity of a populated area.
A SigAlert was issued at 2:30 p.m. because of the traffic jam on the Corona Expressway and connecting freeways.
About 6:25 p.m., the fire’s size was downgraded from 120 acres to 100 and it was 5 percent contained, although its progress had been stopped, according to Cabral.
