An active police investigation has shut down a key Oahu freeway stretch, and it's bad news for anyone commuting this morning.

• The H1 Freeway eastbound and the North School Street overpass are closed because of an ongoing police investigation.
• The closure started in the early morning hours with no word yet on what triggered it.
• Drivers heading eastbound on H1 are being rerouted off at the Vineyard Boulevard exit.
• Police have not said when the freeway will reopen, so delays could stretch through the morning commute.

Outlook: Expect continued delays and detours until police clear the scene, with updates likely later in the day.
