The completion of the Alaskan Way Viaduct program will create nine acres of revitalized open public space adjacent to the downtown Seattle waterfront.
In 2009, then Washington Governor Chris Gregoire (seated) signed the budget bill for the AWV replacement program. She was joined at the time by (back, left to right) Rep. Judy Clibborn, House Transportation Committee chair; Paula Hammond, Washington State Secretary of Transportation; and Senator Mary Margaret Haugen, Senate Transportation Committee chair.
