One man is dead and another slightly injured after a single vehicle crash on the H-1 freeway overnight.

All lanes of the H-1 East were closed at the Pearl City offramp following the 12:25 a.m. incident near the Kamehameha Highway overpass.

The Honolulu Police Department says two Waipahu men, ages 39 and 21, were on the freeway heading toward Honolulu when the 39-year-old driver suddenly lost control of the vehicle and crashed into the guardrail multiple times. The vehicle then traveled up an embankment next to the right shoulder of the freeway and struck a tree.

Emergency responders transported the 39-year-old to a hospital in critical condition, where he later died. The man’s identity has not been released.

The 21-year-old, who suffered minor injuries, refused further medical treatment.

All lanes of the H-1 were reopened to traffic around 3 a.m. today.

HPD said alcohol appears to be a factor in the crash; an investigation is ongoing. This is the 13th traffic fatality of 2019, compared to 9 at the same time last year.
