Deep Bored Tunnel To Replace Alaskan Way Viaduct – Latest Information

Washington Gov. Chris Gregoire, Seattle Mayor Greg Nickels and King County Executive Ron Sims in January 2009 proposed to replace the seismically vulnerable Alaskan Way Viaduct along Seattle's downtown waterfront on State Route 99 with an inland deep bored tunnel. Legislation authorizing and providing substantial funding for the tunnel passed the state senate and house, and on May 12 was signed into law by Gov. Gregoire. The tunnel is expected to cost $1.2 to $2.2 billion, most likely $1.9 billion, including a cushion for cost overruns. The legislation provides $2.8 billion for tunnel construction and Viaduct replacement. Other, related projects - funded by the city, county and Port of Seattle - would bring the total package's cost to $4.2 billion.  Here is the bill, as approved.
