Washington was indeed a Dave Filpus state, with no specific current maintainer (same as with several other states, including his and Tim's, not yet taken over by other team members).
The Future US 395 signs have been around for many years, at least since 2012 when I was last in Spokane.
Progress is being made to complete the bypass, but the timetable for completion (including an "interim connection" to I-90 that will still cost ~$750 million) is unclear. I think we can wait until WSDOT puts in for AASHTO approval to move US 395 to the bypass. We haven't mapped Future US routes like we do Future Interstates, and I would not start now.
