Puget Sound Gateway Funding and Phasing Study

In 2012, following two decades of project development, WSDOT began an effort to develop an integrated, sustainable approach to completing the SR 167 and SR 509 corridor connections to I-5 while relieving congestion and improving mobility between Tacoma and Seattle.

Specifically, the Puget Sound Gateway Project study:

  • Developed a program approach that efficiently integrates the SR 167 and SR 509 completion projects.
  • Built stakeholder support by identifying a phased approach that met regional and statewide priorities and needs.
  • Included national and local experts who developed phasing concepts, cost estimates, project delivery and financing strategies.
  • Created an implementation plan to guide the Gateway project forward.
