Puget Sound Gateway Program

SR 167 and SR 509 Puget Sound Gateway Project Map

Project news

  • On January 16, 2018 the Federal Highway Administration (FHWA) approved the National Environmental Policy Act (NEPA) Re-Evaluation of the SR 509 Completion Project
  • We met with our Steering and Executive Committees in late March and early April to discuss project updates and next steps.

What is the Puget Sound Gateway Program?
The Puget Sound Gateway Program is comprised of two unique projects, SR 509 and SR 167, which together make major improvements to relieve traffic congestion and improve freight mobility. The Gateway Program is the key to enhancing the state's economic competitiveness, both nationally and globally, by connecting the state's largest ports to key distribution centers in King and Pierce counties and to eastern Washington.

Needs & benefits

  • Relieving traffic congestion and completing critical freight links between the ports of Seattle and Tacoma and key distribution centers, warehouses, and industrial areas in King and Pierce counties.
  • Supporting regional job growth and economic growth at the state's two largest ports.
  • Improving regional mobility and relieving congestion on local roads and highways by providing new, more efficient travel options.
  • Supporting master land use plans and economic development plans developed by cities in the Gateway corridors.

Next Steps:
WSDOT is undertaking a Practical Solutions Process for both the SR 509 and SR 167 projects. This process allows us to take a fresh look at the previous project plans and ensure we are designing to actual demand and needs. Part of the Practical Solutions Process includes reengaging stakeholders in both of these corridors to review design and potential changes.
