A head-on crash has shut down Kamehameha Highway in the Waiahole/Waikāne area, snarling traffic for miles in both directions.

• Seven people were injured in the collision, with police, fire crews, and ambulances on scene.
• Both lanes are blocked, and there's only one main road through the area, so backups stretch for miles.
• Drivers are being told to avoid the area if possible and use the H2 and North Shore route instead to reach Windward Oahu.
• No reopening time has been given yet.

Outlook: Expect the closure and heavy delays to continue until crews clear the scene and reopen the highway.
