It happened just before 6am in the 11200 block of Westpark Drive.
Westbound lanes of Westpark were shut down between Rogerdale and Wilcrest for the investigation.
According to police, a 19-year-old man was speeding when his green Mazda 3 left the roadway and hit two trees and a light pole. The victim died at the scene. His name has not been released.
Investigators believe fog also may have been a factor.
The car's engine caught fire. No other vehicles were involved, officials said.
