  • Both the city’s Comprehensive Plan and WSDOT’s I-405 Master Plan call for a new interchange in the South Downtown area
  • No new access to support growth
  • Maintains existing conditions with no further critical area impacts
  • This alternative establishes a baseline to compare travel time savings for the other alternatives
  • Without adding access to I-405, the city and WSDOT expect congestion to increase and lead to more rear-end collisions
  • Does not require acquiring property to build improvements
  • No additional access to support future property developments
  • No cost
