Seattle’s Alaskan Way Viaduct (2007-present)

Washington State Governor Chris Gregoire, then-King County Executive Ron Sims and Seattle Mayor Greg Nickels announced on January 15, 2009 a break-through agreement to resolve a longstanding dispute over the replacement of the at-risk Alaskan Way Viaduct, a 60-year-old stacked highway that separates downtown Seattle from the waterfront. The recommendation – put forward by the three executives and the Port of Seattle and approved by the Washington State Legislature this spring – calls for construction of a deep-bored tunnel under downtown Seattle, as well as significant improvements to current transit service and city streets. The recommended approach, expected to cost $4.2 billion, is to be completed by 2015.

CONCUR’s role in the project over the past two years has focused on collaborative process design, strategic planning advice and stakeholder involvement. Click here for a copy of the final signed agreement (PDF).
