The Alaskan Way Viaduct Replacement Program is making great progress.  The contractor, Seattle Tunnel Partners, is finishing up construction of the double-deck road along with electrical/mechanical and plumbing systems (see the progress here). STP accomplished a tremendous amount of work in 2017, which you can see in this video (the pictures say it all).

Also, STP’s latest schedule moves up their substantial completion date to 15 Aug 2018.  We stress there is a tremendous amount of work ahead installing operational and safety systems and commissioning the tunnel.  It’s important to note that once STP completes the tunnel, WSDOT will need several weeks to connect the highway to the tunnel and build the final ramps. But we are cautiously saying the tunnel could be open by this fall. This new web post is a great reference for people interested in following the progress of the works.

WSDOT is currently planning for the grand opening of the tunnel and looking forward to the demolition of the viaduct.  Should be an exciting year! 01/18.
