1:49 PM: That photo tweeted by SFD shows a truck crash that has closed the southbound Alaskan Way Viaduct from the Battery Street Tunnel southward. No injuries, and the driver got out OK, but the SB lanes of The Viaduct will be closed until this is cleared.
Buses are being rerouted too, according to an alert just in from Metro. Updates to come.
2:32 PM: A tow truck is on scene.
3:23 PM: No time estimate yet on SB Viaduct reopening. But there’s some bad news if more people head to the West Seattle Water Taxi to get around the 99 problem – King County just sent an alert that the smaller Spirit of Kingston is on the WS route tonight. Meantime, most SB surface routes are backed up, according to info including the SDOT Travelers’ Map (look for the red).
3:32 PM: The southbound Viaduct has just reopened. The left lane is closed for repairs, though.
6:35 PM: The repair closure isn’t over yet, according to SDOT.
6:57 PM: All lanes are open again. (See comments below for some examples of this afternoon/evening’s nightmarish traffic.)
