(SDOT cam looking north at 99 through SODO, from the WSB Traffic cams page)
7:40 AM: Just got word of the Battery St. Tunnel closure from SDOT via Twitter. If it lasts for long, 99 northbound will be worse than usual – so if you’re heading into downtown, you might want to opt for 1st or 4th exits from the bridge.
7:51 AM: SDOT says it’s now been cleared and reopened.
