Built in the 1950s, the Alaskan Way Viaduct was damaged in the 2001 Nisqually Earthquake. While it was strengthened and safe for daily use, the structure remained seismically vulnerable. The viaduct’s role in moving people into and through downtown Seattle will be replaced by the new SR 99 tunnel and a new Alaskan Way surface street now under construction.
