The Knox County Sheriff's Office says one man died in a single-vehicle crash on Pellissippi Parkway Wednesday evening.

Dennis Gowey, 64, of Powell died after driving a white van northbound on Pellissppi Parkway around 6 p.m. when it crossed over the median into the southbound lane, and hit trees on the side of the road.

The sheriff's office does not believe drugs, speed or alcohol were factors in the crash. The driver was wearing a seat belt.

Crews took Gowey's body to the Knox County Medical Examiner's Office.
