UPDATE: I-77 truck fire caused by brake problem, authorities say
UPDATE: 8/10/18 4;30 P.M.
A tractor trailer that caught fire early Thursday morning causing a section of Interstate 77 in Jackson County to be closed for nearly 18 hours was the result of brake problem.
According to an incident report from the West Virginia Department of Environmental Protection, the tractor trailer was carrying the mineral ulexite when its brakes caught fire about 1:40 a.m. Thursday in the northbound lane of I-77 just north of Silverton exit 146.
Roughly 21,000 pounds of the mineral caught fire and turned into a powdery substance that covered the highway.
Authorities originally said the truck was hauling some type of fertilizer.
The highway remained closed until about 9 p.m. Thursday.
The DEP report noted there was no environmental damage.
The truck was owned by Star Point Shipping of Brooklyn Park, Minnesota.
The area opened back up at 9 p.m., according to deputies with the Jackson County Sheriff's Office.
Jackson County officials say the road could reopen around 8:30 p.m. or 9 p.m. Thursday night. That could change. WTAP will keep you updated.
Northbound Interstate 77 is closed in Jackson County while crews continue to clean up after a tractor trailer hauling fertilizer caught on fire.
Traffic on I-77 northbound is being detoured off Exit 146 at Silverton onto Greenhills Road to Route 21 North and back to I-77 at Rockport.
Jackson County Sheriff Tony Boggs says it happened overnight just north of the Silverton exit on I-77.
He says a hazardous materials team is on the scene, and it's unclear when the interstate will be re-opened.
