Summary: This tool was a 2013 John and Jane Public Competition winner. From TRB Committee ADA 60: The SR 99 Alaskan Way Viaduct’s south end, between South Holgate and South King streets, is being replaced with two side-by-side bridges. In addition, the structure’s waterfront section is being replaced with a bored tunnel beneath downtown Seattle. Parsons Brinckerhoff created a flash tool that allows the public to see the project at key points in the schedule and to view detour routes and impacted areas from different angles. SR 99 through downtown Seattle carries approximately 110,000 vehicles daily, so public outreach and information has been critical. Since its inception, Parsons Brinckerhoff has continued to work with Washington State Department of Transportation to revise and update the tool to reflect current schedules and milestones.
