A car fell from the Alicia Parkway bridge over the Amtrak train tracks Friday evening just before 7 p.m., killing the driver, said Lt. Gary Strachan with the Orange County Sheriff's Department.
According to Strachan, the driver lost control, hit the center divider and drove off the bridge between lanes; his Lexus landed upside-down on the train tracks.
No other people or vehicles were involved in the accident, authorities said.
The deceased was identified as Craig Engstrom, 52, of Mission Viejo. He died at the scene.
Strachan said that trains were stopped in both directions. There was no train involved in the incident.
Mission Viejo student Anastasia Bolton and Danny Akins were killed under the same bridge in Sept. 2010 after being struck by a train.
Update: The victim's city of residence has been updated by the Orange County coroner's office.
