Digging In: The Construction & Activities of Seattle's Big Bertha
The State Route 99 Alaskan Way Viaduct has been a fixture of Seattle's skyline and a vital north-south route through downtown for nearly 60 years. In summer 2013, the world's largest-diameter tunneling machine began digging the SR 99 tunnel, the centerpiece of the state's efforts to replace the seismically vulnerable viaduct. At the April Queen Anne Science Café, join Dave Sowers, Deputy Program Administrator for the Alaskan Way Viaduct Replacement Program, for a talk on tunneling activities and construction near the tunnel's north and south portals.
