9:04 AM: Avoid Highway 99 TFN – WSDOT says it is blocked both ways at the Battery Street Tunnel by a jackknifed semi-truck. More info as we get it.
9:21 AM: Good news – tipster Jonathan says the 99 problem has been cleared – and the camera view appears to verify that. (As does WSDOT via Twitter.)
11:50 AM: Now there’s a crash on the eastbound West Seattle Bridge, before the Delridge on-ramp. Here’s the city camera for the Fauntleroy approach so you can check if the backup’s cleared:
1:39 PM: Commenters report trouble on 99 again. And there are some problems on I-5 too. If you really HAVE TO head out – here’s the custom list of traffic-related Twitter users (including WSDOT, which does tweet on weekends) that we watch. See traffic cameras here.
5:56 PM UPDATE: We’re about to launch a new traffic update for the evening. There’s a crash on the northbound Viaduct – no details, just that it’s on the SFD 911 log as “motor vehicle accident/freeway,” northbound 99 near Seneca. Meantime, the tree blocking 35th by 108th is now cleared.
6:25 PM UPDATE: Evening updates on traffic and weather are here.
