A 45-mile stretch of State Route 260 was closed Thursday afternoon for more than 12 hours after a fuel tanker crashed, spilling gasoline everywhere.
Authorities closed the highway from Star Valley to Heber at about 11 a.m. when the tanker crashed 10 miles west of Heber, spewing 7,700 gallons of diesel fuel onto the roadway, according to the Arizona Department of Public Safety.
The driver of the truck was flown to a Scottsdale hospital with serious injuries. No other vehicles were involved.
Hazmat crews had the road cleaned up by 8 p.m. and the road was reopened, said Officer Carrick Cook with the Arizona Department of Transportation.
As an alternate, some motorists used U.S. 60 to travel between Phoenix and Show Low and Highway 87 north to Winslow, then eastbound on Interstate 40 to reach Holbrook.
It is unknown what caused the driver to drive off the right side of the road, Cook said.
