A section of I-15 was closed for 15 hours after a tanker-trailer of propane came loose, rolled down an embankment and ruptured.
Much of the propane dissipated, the rest was pumped into another truck and the highway was reopened at 10 p.m. Thursday. Traffic had been routed off I-15 between Nephi and its I-70 junction.The accident occurred about 7 a.m. when the truck, belonging to Mountain States L-P Gas of Tremonton, lost its "pup" trailer about 12 miles north of Scipio.
The liquid, stored at minus-150 degrees, turned gaseous on contact with air, Utah Highway Patrol trooper Margaret Hardie said.
The driver, Kevin Johnson, no age or address available, was unhurt.
"Of course, the gas is extremely flammable so we shut down the freeway" several miles in either direction from the spill.
There was no danger that the propane would pollute the nearby Sevier River, UHP dispatchers said.
