Puget Sound Gateway Program

SR 167 and SR 509 Puget Sound Gateway Project Map

Project news

  • We talked with contractors and consultants interested in building the SR 167 Completion Project and the SR 509 Completion Project at contracting events in early October.
  • We’ll be posting our first Request for Qualifications (RFQ), for the  SR 167/70th Avenue E. Vicinity Bridge Replacement Project, on WSDOT’s Contract Ad and Award Design-Build Projects webpage on October 25, 2018.
  • We are holding a voluntary submitters meeting about the  SR 167/70th Avenue E. Vicinity Bridge Replacement Project for interested parties on Friday, Nov. 2, 2018 from 10 to 11:30 a.m. at the Fabulich Center (3600 Port of Tacoma Road Tacoma, WA  98424).
  • Local partners confirmed their support for the Puget Sound Gateway Program in July when they signed a funding memorandum of understanding that committed local contributions for construction.
  • A tolling policy evaluation process is underway to determine feasible tolling scenarios for the Puget Sound Gateway Program.
  • We participated in nine fairs, events, and festivals this summer to talk with the public about the Program.

Needs & benefits

What is the Puget Sound Gateway Program?
The Puget Sound Gateway Program is composed of two projects: the completion of SR 167 in Pierce County, and the completion of SR 509 in King County. These projects provide essential connections to the ports of Tacoma and Seattle and will help ensure people and goods move more reliably through the Puget Sound region. 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.

Delivering the SR 167 and SR 509 projects under one program will allow the Washington State Department of Transportation (WSDOT) to realize efficiencies in planning, environmental review, design, and construction.

Program Benefits

  • Regional mobility. Reduces traffic congestion on local roads and highways by completing connections and providing alternate routes to I-5.
  • Airport access. Provides a new connection between I-5 and Sea-Tac Airport from the south for both passengers and air cargo.
  • Regional job and economic growth. Supports regional job growth and economic growth associated with the state’s two largest ports.
  • Intelligent transportation. Improves safety and manages congestion with tolling.
  • Advanced wetland mitigation. Improves water quality and wildlife habitat by completing environmental improvements in advance of both projects.
  • Freight connections. Completes critical freight links between the Puget Sound marine ports and the industrial areas of South King and North Pierce counties.

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.


The program was funded over a 16-year timeline. The schedule below reviews anticipated design, construction and completion timeframes. Based on the funding plan under Connecting Washington, major construction for a first stage would likely occur in 2019-2026, and a second stage in 2025-2031.


In July 2015, the Washington State Legislature and Governor Inslee acted to fund the Puget Sound Gateway Program through the Connecting Washington Revenue Package.

Funding for the total Puget Sound Gateway Program will come from the state gas tax, tolls, local contributions, and potential federal grants. Total funding for the project is $1.88 billion; $1.57 billion will come from the Connecting Washington Revenue Package, tolling will be $180 million, and local contributions will be $130 million. WSDOT is also seeking a federal grant.
