Scott's death was being investigated as a suicide, Los Angeles County Coroner's Lt. Joe Bale said.
The 68-year-old Scott jumped from the Vincent Thomas Bridge spanning San Pedro and Terminal Island in Los Angeles, authorities said.
U.S. Coast Guard Lt. Jennifer Osburn told the Daily Breeze that a suicide note was found inside Scott's black Toyota Prius, which was parked on one of the eastbound lanes of the bridge.
The British-born Scott was producer Ridley Scott's brother.
