Puget Sound Gateway Program

Project news

  • Big news as we move into 2020! Construction starts in February. Highlights include
    • Breaking ground on the first phase of the SR 167 Completion Project, which includes a new, wider 70th Avenue East bridge over I-5 in Fife and a roundabout on SR 99 (learn more on the SR 167 Construction page)
    • We have an agreement with Sound Transit to construct a new SR 99 bridge as part of its Federal Way Link Extension work. The bridge will allow the new SR 509 roadway to travel under SR 99 and the future light rail guideway (learn more on Sound Transit’s Federal Way Link Extension page).
  • The Legislature provided toll authorization in 2019. This solidifies the $180 million in toll revenue needed for Program funding
  • Check out our video on the Gateway Program to see firsthand why so many people are excited about the SR 167 and SR 509 Completion Projects.

Needs & benefits

The Puget Sound Gateway Program is composed of two projects to provide essential connections to the ports of Tacoma and Seattle and help ensure people and goods move more reliably through the Puget Sound region. Delivering the SR 167 and SR 509 Completion projects under one program allows WSDOT to maximize efficiencies in planning, environmental review, design, and construction.

The SR 167 Completion Project will build the remaining four miles of SR 167 between Meridian Ave and I-5, completing a long-planned connection to I-5. The project also includes a two-mile connection from I-5 to the Port of Tacoma.

The SR 509 Completion Project will extend SR 509 to I-5 near SeaTac, add a southern access point to Sea-Tac International Airport, and improve service between industrial districts by allowing general purpose traffic and trucks to bypass I-5, SR 99, and local streets.

Program Benefits

The Gateway Program is 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, to eastern Washington and beyond. When constructed, the SR 167 and SR 509 Completion projects will offer benefits to the whole region, including:

  • Regional mobility. Reduces traffic congestion on local roads and highways by completing connections and providing alternate routes to I-5.
  • National economy. The movement of cargo through the Puget Sound offers economic benefit to the region and nation. Washington is the nation’s second-most trade-dependent state, with exports as a key driver of job growth and economic prosperity.
  • 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. Establishes a new southern connection between I-5 and Sea-Tac Airport for both passengers and cargo
  • Regional job and economic growth. Supports regional job growth and economic growth associated with the state’s two largest ports.
  • Intelligent transportation. Electronic tolling on the route will manage congestion, which improves safety and reliability for all users.
  • Advanced wetland mitigation. Improves water quality and wildlife habitat by completing environmental improvements in advance of both projects.


In addition to beginning construction on Stage 1a of the SR 167 Completion Project in 2020, Sound Transit’s Federal Way Link Extension Light Rail contractor will start construction on Stage 1a of the SR 509 Completion Project in 2020. This partnership helps ensure the light rail extension and SR 509 Completion Project are built efficiently and on schedule.

The Program is now expected to be complete in 2028, three years ahead of schedule. The new schedule is a result of the State Legislature advancing funding for the Program. The original 16-year timeline targeted completion in 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.

Gateway Program funding totals $1.96 billion from four sources: 1) $1.57 billion from the Connecting Washington funding package; 2) $130 million from local contributions; 3) $180 million from tolling; and 4) WSDOT is seeking federal grant funding.
