HONOLULU - Honolulu police are investigating a deadly hit-and-run that happened late Wednesday on North Nimitz Highway.

At around 10:30 p.m., police say a 35-year-old Wahiawa man was driving eastbound on the H-1 Freeway Airport Viaduct when he crashed into a concrete barrier.

Investigators say the man got out of his vehicle, walked to the shoulder of the freeway and somehow fell 40-feet onto North Nimitz Highway.  The man was in the middle of Nimitz Highway when a vehicle hit the man and never stopped.  The man was taken to the hospital where he later died.

Police have not released a description of the vehicle.  It's unclear if speed or alcohol played a role.  This is the second traffic fatality of 2018 on Oahu.

Anyone with information is asked to call police at 723-3413.
