CHESTER -- One man is dead after the pickup truck he was driving struck a bridge pylon on Interstate 77 near mile marker 60 in Chester County on Monday afternoon, authorities said.
William Anthony Butler, 48, of Concord, N.C., died from the injuries he suffered during the single-vehicle crash, said Chester County Coroner Terry Tinker.
There were no other passengers, and no one else was injured.
The accident happened around 2:15 p.m. when the truck, a 1997 Ford pickup, veered off the left side of the northbound traffic lanes and into the median, Lance Cpl. Jeff Gaskin of the S.C. Highway Patrol said.
He said the truck traveled down the middle of the grassy median for about a half mile before colliding with the column supporting an overpass at mile marker 60.
It is unclear why the truck left the road, Gaskin said. The crash is under investigation, but neither speed nor alcohol iss believed to be a factor, he said.
Gaskin said the driver, though not wearing a seat belt, was pinned inside the vehicle. He died at the scene.
An autopsy and toxicology tests will be performed today, Tinker said.
Chester County Director of Emergeny Management Eddie Murphy said the vehicle caught fire after the crash. The spectacle, combined with several emergency crews on the scene, slowed traffic in both directions for several hours.
