LUDLOW >> A semi-truck’s trailer containing 76,000 pounds of beef ribs caught fire Saturday night, causing westbound lanes of the 40 Freeway to be shut down for about two hours, authorities said.

The fire occurred when the rear wheels of a trailer ignited around 6 p.m., according to the San Bernardino County Fire Department.

By the time firefighters arrived, the truck was disconnected from the trailer, which was fully engulfed in flames, spokesman Al Franco said in a written report.

Firefighters said it was a typical truck fire but it had a “wonderful BBQ beef rib odor to it,” according to Franco’s report.

The truck departed from Flagstaff, Ariz., and was scheduled to arrive in Wilmington, in the harbor area, Franco said.

Firefighters used about 6,500 gallons of water while fighting the fire, which was contained in an hour and fully extinguished two hours after fire personnel arrived, according to Franco.

No injuries were reported and the cause of the fire is being investigated, Franco said.
