Puget Sound Gateway Program

SR 167 and SR 509 Puget Sound Gateway Project Map

Project news

  • We’ve made progress the first half of 2019! Some highlights include:
    • We will complete both SR 167 and SR 509 three years earlier than planned! The Washington State Legislature authorized us to accelerate the SR 167 and SR 509 project schedules by three years, which means we will complete construction in 2028. We’re excited to deliver the projects’ benefits three year earlier than originally planned.
    • The Legislature provided toll authorization. This solidifies the $180 million in funds needed for Program funding.
  • Looking forward to 2020, we will:
    • Break ground in early 2020 on a new, wider 70th Avenue East bridge over I-5 in Fife.
  • Check out our new video about the Gateway Program and hear firsthand about why so many people are excited about the SR 167 and SR 509 Completion Projects.

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 large distribution centers in King and Pierce counties and to eastern Washington.

Delivering the SR 167 and SR 509 projects under one program allows 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.
  • Freight connections. Completes critical freight links between the Puget Sound marine ports and the industrial areas of South King and North Pierce counties.
  • 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.

Next Steps
In addition to beginning construction on Stage 1a of the SR 167 Completion Project later this year, Sound Transit’s Federal Way Link Extension Light Rail contractor will start construction on Stage 1a of the SR 509 Completion Project. This partnership helps ensure that the light rail and 509 projects are built efficiently and on schedule.


The program was originally funded over a 16-year timeline with targeted completion in 2031. The new schedule, which is a result of the State Legislature advancing funding for the Program, anticipates project completion in 2028.


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

The Puget Sound Gateway Program is funded through the state gas tax, tolls, local contributions, and potential federal grants. The total cost of the Program is $1.96 billion; $1.57 billion will come from the Connecting Washington Revenue Package, tolling revenue is expected to be $180 million, and local contributions will be $130 million. WSDOT is also seeking a federal grant.
