WSDOT‘s big alert announcement is expected tomorrow, but in the meantime, we brought you early warning September 22nd that next weekend (Saturday-Sunday, October 8-9) will bring the next twice-yearly inspection/maintenance closure of the Alaskan Way Viaduct, and we’re reminding you again today. This is scheduled once again as a shutdown 6 am-6 pm each day, but recent closures have tended to end early.

Also note, next Saturday’s closure will include a stretch north of the Battery Street Tunnel, between Denny Way and Valley Street, 6 am-3 pm, with Valley remaining open for detours.

P.S. We also expect to hear tomorrow if the Highway 99 tunneling machine has passed the halfway point along its 9,270-foot route – WSDOT updates this page on Mondays and Thursdays, and as of three days ago, it was less than 100 feet from that milestone.
