Overview: The Alaskan Way Viaduct has been a fixture on Seattles waterfront and a vital north-south route through downtown for more than 60 years. The Washington State Department of Transportation is replacing the seismically vulnerable structure with the nations largest-diameter bored tunnel and other projects. Join us for an overview of this project and insight into the geotechnical challenges encountered, including ground settlement observations while mining with the 57.5-foot diameter TBM, and the unexpected results of groundwater depressurization in the Pioneer Square neighborhood.
