LOS ANGELES (AP) -- Authorities say a construction worker has fallen 50 stories to his death from a skyscraper being built in Downtown Los Angeles.

Fire Department spokeswoman Margaret Stewart says the man plunged from the unfinished tower on South Figueroa Street Thursday and hit the back of a passing car.

Stewart says the driver didn't appear to be injured but she was taken to a hospital for examination.

The death occurred at the construction site of Wilshire Grand Center, which will be the tallest building west of the Mississippi.

 A ceremony was held earlier this month when the top beam was hoisted into place on the 73rd floor.

The $1 billion office and hotel tower is expected to open in early 2017.
