Gary Russel, 18, killed, after his car left the westbound I-40 roadway near Kingston Springs, and crashed into a cliff face.
Tennessee Highway Patrol responded to a fatal crash in Cheatham County on Saturday afternoon.
The crash happened around mile marker 191 on I-40, when THP says a driver swerved for an unknown reason and struck a cliff face. The vehicle then went back into the roadway and came to rest in the left lane.
The driver, 18-year-old Gary Russel, was killed in the accident. Police believe he might've survived if he had been wearing his seatbelt.
The westbound lanes were closed for nearly two hours while officials cleared the scene.
All lanes are now reopened.
