A man was killed early Monday morning in a single-vehicle crash at the Port of Long Beach, according to authorities.

The crash was reported at 3:09 a.m. in the area of Ocean Boulevard and Highway 47, Long Beach police said. That is just west of Pier T.

Police say the man was driving a 2001 Chevrolet Blazer southbound on Highway 47 at a high rate of speed when the vehicle crossed through the Ocean Boulevard intersection and drove into an exit ramp for a shipping terminal. 

The vehicle then hit cement barriers and overturned, police said, adding that there were no other vehicles involved or passengers in the car. 

When officers arrived at the scene, they found the man unresponsive and partially ejected from the vehicle, police said. Long Beach Fire personnel arrived soon after and determined he was dead, according to the LBPD. His name was not released while authorities work to notify his relatives, though the Los Angeles Medical Examiner’s Office identified him as a man in his 50s.

At this time, police say speed and impaired driving may have played a role in the crash. The investigation is ongoing, the LBPD said.
