If you like planning ahead – note that the next full-weekend Highway 99/Alaskan Way Viaduct inspection closure is on the schedule, though not formally announced yet: According to the Construction Lookahead page jointly published by SDOT and WSDOT, it’s two weeks away – late Friday night February 28th, through early Monday morning March 3rd. Again, this is the regular twice-yearly inspection closure, not related to the tunnel construction.
