Cal Fire said Thursday a blaze near Route 76 in Vista had been halted at less than 15 acres with no structures threatened.
The brush fire, dubbed the Spur Fire, started around noon at Spur Avenue and Hutchinson Street.
Authorities closed eastbound Route 76 at Melrose Drive while crews fought the blaze, in a canyon east of Guajome Regional Park. Flames blackened about 12 1/2 open acres, but caused no reported structure damage or injuries.
Ground crews and personnel aboard air tankers and water-dropping helicopters attacked the flames. The fire spread away from nearby residences and toward SR-76, said Thomas Shoots, a fire captain.
Authorities shut down the eastbound lanes of the highway during the firefighting operation, which took a little over an hour.
Officials quickly concluded the blaze was “human caused,” but exactly how it erupted remained under investigation in the late afternoon, Shoots said.
