OKLAHOMA CITY -- A metro interstate is again open after a hazardous materials truck crash on Saturday afternoon.
According to the Oklahoma Highway Patrol, both I-40 westbound at Council Road and I-40 eastbound at the Kilpatrick Turnpike have been reopened.
Troopers said the spill happened about 1:30 p.m. Saturday when a truck carrying calcium carbide overturned, spilling its contents.
Trooper Betsy Randolph said, "The substance is highly flammable when wet."

Albany fire investigators say the failure of a seal inside one or more drums of calcium carbide probably caused the fire at Industrial Welding Supply on Sunday night.
Fire Marshal Mike Trabue issued a report on the fire late Tuesday.
He said fire department investigators, with the cooperation of the company, had completed an investigation of the explosion and fire at the business, 3415 Pacific Blvd. S.W.
Responding to the alarm, firefireghters found a tarp-covered storage pile of flammable gas-producing calcium carbide in an outside storage yard on fire.
Investigators determined that one or more drums were most likely damaged during shipping, causing the seal for one or more drum lids to fail.

A chemical fire Sunday night at Industrial Welding and Supply in Albany prompted the closure of Pacific Boulevard and the evacuation of about 250 nearby residents, but firefighters got the blaze under control and no injuries were reported.
The Albany Fire Department responded to Industrial Welding and Supply, 3415 Pacific Blvd S.W. at about 10:24 p.m. Sunday to an explosion and flames reported by a 911 call.
Firefighters arrived within approximately four minutes and observed several small explosions and fire involving approximately 360 square feet of piled storage of unknown materials located outside the building.
Firefighters initially applied water to extinguish the fire; however, these efforts and a passing rain shower intensified the burning. Firefighters immediately ceased fire suppression efforts and backed away to a safe distance from the burning materials.
A representative from Industrial Welding and Supply responded to the scene and identified the burning material as 4,000 to 5,000 pounds of calcium carbide in 200 pound drums.
Calcium carbide is a grayish-black irregular lump solid material used to manufacture flammable acetylene gas. The acetylene gas, and a significant amount of heat, is created when the chemical comes in contact with moisture.
