A 34-year-old man died today after he apparently lost control of his motorcycle while making a turn on Kalanianaole Highway near Sandy Beach.

According to police, the man was riding a 2004 Honda motorcycle, heading west, when he failed to negotiate a turn. The motorcycle collided with a guardrail, ejecting the man onto the roadway.

He was pronounced dead at the scene.

Kalanianaole Highway was closed this evening in both directions between Hanauma Bay and Sandy Beach Park. It was reopened by 9 p.m.

Police said speed appears to have been a factor in the crash. It is unknown if alcohol or drugs were involved.

The rider was wearing a helmet.

This is the ninth traffic-related fatality on Oahu this year, compared to seven at the same point last year.
