2013 Engineering Lecture Series: Tunneling Toward a New State Route 99 Corridor
The 2013 Engineering Lecture Series examines our national and regional infrastructure up close. From road and rail networks to water and sewer conduits to national power and natural gas grids, life is dependent on systems.
Join us for the final of this series of three lectures discussing the future of the transportation system in our region.
Tunneling Toward a New State Route 99 Corridor
Matthew Preedy, P.E. (B.S. CEE ’92) Deputy Program Administrator, Alaskan Way Viaduct Replacement Program, Washington State Department of Transportation
In the summer of 2013, Bertha, the world's largest-diameter tunneling machine began a historic journey beneath downtown Seattle. Its purpose: dig a tunnel to replace the SR 99 Alaskan Way Viaduct, a double-deck highway that has spanned the downtown waterfront for more than half a century. Learn about the decade-long process of planning and debate that went into the tunnel, and get an update on how this massive project is unfolding.
