From today’s quarterly meeting of the Alaskan Way Viaduct Stakeholders meeting:

The dates are set for this year’s semiannual AWV inspection closure – scheduled for Halloween weekend, 6 am-6 pm on Saturday, October 31st, and again on Sunday, November 1st. The Viaduct will be closed both ways between the West Seattle Bridge and Battery Street Tunnel. WSDOT said at this afternoon’s meeting that besides the inspection, they’ll do some maintenance as usual – in particular, fire-suppression systems in the BSTunnel need some work.

Also at the meeting, WSDOT played the video that we featured here earlier in the day, showing what’s been happening with the tunneling machine as work continues to get it ready to start tunneling again later this year. The Viaduct closure that’s expected when the machine goes beneath the structure could last up to two weeks. Assuming everything goes as currently projected, the machine will stop in a long-planned “safe zone” just outside the edge of the structure, so it can get a checkup to see how it’s doing after what would be the first few weeks of digging.
