A young woman was killed when a car she was riding in barreled into a divider on the Williamsburg Bridge this morning. Police say the driver was drunk, and the driver, the victim and another passenger had been celebrating the dead woman's 21st birthday.

The crash occurred on the Williamsburg Bridge before 3:30 a.m. The driver, reportedly a 26-year-old off-duty traffic enforcement officer, was driving an Infiniti from Manhattan into Brooklyn when he lost control and hit the divider and then a support column, which split the car in two.

The woman, who was in the backseat of the car, was thrown from the vehicle. Video from the Manhattan-bound side shows half of the car in the roadway:

The driver and a 24-year-old male passenger were both treated for minor injuries at Bellevue Hospital. The driver is expected to be charged.

Update: The victim was identified as Amanda Miner, of Brooklyn. Stefan Hoyte, an NYPD traffic enforcement agent, was charged with vehicular manslaughter, criminally negligent homicide, DWI and speeding.
