A long stretch of Interstate 5 (I-5), a major highway that runs the length of the West Coast from Canada to Mexico, was closed to prevent motorists from being trapped by the blaze. There were some reports that homes had burned but he could only confirm that an outbuilding and two mixed-use commercial and residential buildings had been damaged.
Firefighters were also tired, moving from one major blaze to another, battling one of the last outbreaks of wildfires in California history.
The fire, which officials said was human-caused, forced the continued closure of Interstate 5 for almost 50 miles and leaving residents of the mountain areas on edge, ready to flee if necessary.
The 45-mile (72-kilometer) stretch of highway near the state line with OR has been closed since a fire Wednesday turned hills both sides of the roadway into walls of flame.
Fire spokesman Brandon Vacarro says work crews have cleared away burned and abandoned trucks that littered the road after the swift-moving blaze erupted but they must also determine whether charred 70-foot (21-meter) trees along the road are in danger of falling. The truck stop's facilities were stretched to their limits, cashier Jacob Chapman said Thursday afternoon.
California accounts for 10 percent of all the acreage burned in the USA since 2000, according to the National Interagency Fire Center.
"It's been ridiculously congested".
More than 1.2 million acres of California land were charred and over 1,200 homes destroyed in this year's prolonged fire season that has seen some of the largest wildfires in that state's history. "A lot of the truckers are upset".
The AP noted that Cal Fire has requested additional funding in seven of the past 10 years, though the latest one has come earlier in the year than any previous requests. "They're just stuck, they can't get through and they're sick of waiting around".
California has been hit with one massive blaze after another over the summer, including a blaze not far from the Delta Fire that last month burned about 1,100 homes and killed eight people.
The Carr fire has gone on to ravage 1000 homes and has killed at least seven people, while the Mendocino has been declared the largest in state history, having burnt through nearly 300,000 acres of land.
Officials said the fire was caused by humans, but they didn't say how someone started it.
