The Alaskan Way Viaduct will be closed from South Spokane Street (aka the West Seattle Bridge) to the south end of the Battery Street Tunnel. The Battery Street Tunnel southbound off-ramp and northbound on-ramp at Western Ave will remain open, but all of the other on and off-ramps to the viaduct within this stretch of SR 99 will be closed.
