Posted on Mar 31 2014 3:37 PM

You’ve been hearing a lot lately about our efforts to replace the State Route 99 Alaskan Way Viaduct. This is a big, complex undertaking. And as we all know, we’ve encountered some challenges. Join us this Thursday at 6 p.m. at Milepost 31 as speakers from WSDOT and our tunnel contractor, Seattle Tunnel Partners (STP), explain what's being done to address these challenges and get Bertha, the SR 99 tunneling machine, moving again.


  • Matt Preedy, WSDOT's deputy administrator for the Alaskan Way Viaduct Replacement Program
