On Saturday, with a signed memorandum of agreement between Governor Christine Gregoire and Mayor Greg Nickels, Washington and Seattle formalized their partnership for removing the Alaskan Way Viaduct. As described by the Washington State Department of Transportation, the seven-page agreement "outlines the city and state's construction and funding responsibilities to replace the Alaskan Way Viaduct with the proposed bored tunnel." Last week, Seattle's City Council voted unanimously on a measure to endorse the tunnel and, according to WSDOT, which "authorized the execution of the agreement."
The Alaskan Way Viaduct was damaged by an earthquake in 2001. WSDOT recently released a video (see below) that "simulates what would happen to the Alaskan Way Viaduct and Seawall if another seismic event more intense than the 2001 Nisqually earthquake were to shake the Puget Sound region."
