Interstate 5 usually swarms with trucks and traffic as it winds its way through California.

But the main highway between Mexico and Canada was a ghost road Friday morning along a 45-mile northern stretch that remained closed since a fire two days earlier swept down and turned hills on either side into walls of flame.

Drivers fled in terror and several big-rigs burned Wednesday as the fire erupted on both sides of the artery. Crews managed to remove the burned hulks and abandoned rigs on Thursday but flames continued to burn along an edge of the road in some areas, fire spokesman Brandon Vacarro said.

A decision was expected Friday on whether to reopen the highway but first authorities had to check the safety of the pavement and cut down burned trees next to the road โ€“ some of them 70 feet tall โ€“ that might be in danger of falling down.

The fire had burned more than 34 square miles of timber and brush and prompted evacuation orders for scattered homes and buildings in three counties in and around the Shasta-Trinity National Forest. At times, flames shot up 300 feet high.

Although the fire wasnโ€™t burning near any large towns, Vacarro said about 280 homes were considered threatened. There were some reports that homes had burned but Vacarro could only confirm that an outbuilding and two mixed-use commercial and residential buildings had been damaged.

โ€œIt could be like a bed-and-breakfast, it could be a store with a house above it,โ€ he explained.

Meanwhile, truckers who rely heavily on the I-5 to transport timber and other goods along the West Coast had the unenviable choice of waiting or taking a jammed detour that added 115 miles or so to their journeys.

โ€œThe road is essentially all two lanes on that journey and thereโ€™s some steep hills on there as well so obviously slow-moving trucks going up and down the hill is making it hard to travel,โ€ Vacarro said.

Patience was running thin at the Pilot Travel Center in the town of Weed, near the northern end of the closure. The truck stopโ€™s facilities were stretched to their limits, cashier Jacob Chapman said Thursday afternoon. Parked big rigs lined the roads surrounding the facility.

โ€œItโ€™s been ridiculously congested. Itโ€™s been frantic,โ€ Chapman said. โ€œA lot of the truckers are upset. Theyโ€™re just stuck, they canโ€™t get through and theyโ€™re sick of waiting around.โ€

โ€œThe general mood is just tired and upset. The truckers are exhausted and just want to get going. And the locals just want a break from the wildfires,โ€ Chapman said.

โ€œWe want our towns to stop being on fire,โ€ he added.

California has been hit with one massive blaze after another, including a blaze not far from the Delta Fire that last month burned about 1,100 homes and killed eight people.

The unrelenting flames have drained Californiaโ€™s firefighting budget and prompted nearly $1 billion in property claims even before the start of the dangerous fall fire season, officials said Thursday.

The deadly Carr Fire and another in the Mendocino area โ€“ the two largest blazes in the state this year โ€“ destroyed or damaged 8,800 homes and 329 businesses, Insurance Commissioner David Jones said.

Victims have filed more than 10,000 insurance claims so far, totaling $845 million.

โ€œThe worst may be yet to come,โ€ Jones warned at a San Francisco news conference, noting that California wildfires are typically more destructive after Sept. 1.
