6:04 PM: If you were headed for Highway 99 any time soon – northbound from here, or southbound toward here, you should know there’s a big problem right now: The Battery Street Tunnel is closed in both directions.

6:16 PM: Scanner indicates the fire suppression system in the tunnel went off though there was no fire, and that a shutoff is in the works – “shouldn’t be long” is the exact quote.

6:55 PM: SDOT says the tunnel is now open again, both ways.
