Proposed SR 99 Bored tunnels underground simulation M? March 2010

The Washington State Department of Transportation, in partnership with the Federal Highway Administration, King County, the city of Seattle and the Port of Seattle , f? leads a program to the Alaskan Way Viaduct section of State Route 99, along the L? runs replace Seattle's downtown waterfront. F? R the section between S. King Street Viaduct and the Battery Street Tunnel, there is a continuous process, the environment? BerPR? Ft three alternatives is previous cut-and-cover tunnel and elevated structure alternatives and a bored tunnel alternative in January recommended 2009th This simulation shows the proposed route bored tunnel under downtown Seattle and its N? He other underground structures. A second Supplemental Draft Environmental Impact Statement f? R this project will be published in autumn 2010 ver?. More information? Alaskan Way Viaduct replacement over the www.alaskanwayviaduct.org on the proposed SR 99 tunnel is drilled designed so that an earthquake happens only once every 2500 years withstand avail? Gbar on average (in the range of 9.0 on the Richter scale) without collapsing. We describe the information on our website http, tunnel-like w?

    SR 1999 @ Nausicaan666 The proposed tunnel will be drilled designed so that an earthquake happens only once every 2500 years on average, able to withstand (in the range of 9.0 on the Richter scale), without breaking down. We have the information described on our website, such as tunneling w? Re properties along the proposed route tunnel drilled concern.

    What is the risk of collapse of the tunnel in the event of a major earthquake? The tunnel is uden as part of a series of big en Geb?, Including those in which I will spend the time. What is the risk f? R the foundation and the stability? Of its structures? Over the tunnel?

    @ Goldfndr The proposed tunnel drilled w? Rde in a part of First Avenue run, w? During the transit tunnel l? Runs under Third Avenue. The transit tunnel is in purple on the right side of the video picture. The tunnel Universit? T station is in the 2 minute 20 second mark labeled. - WSDOT
