Puget Sound Gateway Program

Puget Sound Gateway Program

The Puget Sound Gateway Program is composed of two projects that 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.

Project news

  • The first phase of the SR 167 Completion Project builds a new 70th Avenue East Bridge across I-5 replaces an existing two-lane bridge with a new four-lane bridge and a 12-foot-wide path for pedestrians and bicycles. It also builds a new roundabout at the 70th Avenue East/SR 99 intersection, New! View real-time construction cameras
  • The 70th Avenue East Bridge Project also includes a new Interurban Trail parking lot and several hundred feet of new trail. 
  • The first phase of the SR 509 Completion Project partners with Sound Transit to build a new SR 99 bridge as part of Sound Transit’s Federal Way Link Extension work. Combining these projects helps reduce the construction impact to nearby communities.

Needs & 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.

Timeline

In addition to starting construction on SR 167’s 70th Avenue East Bridge Replacement Project in 2020, Sound Transit’s Federal Way Link Extension Light Rail contractor has started construction and will soon start building SR 509’s SR 99 Bridge for WSDOT. Our partnership with Sound Transit reduces the impacts of major construction by building both projects at the same time.

The Gateway Program is targeted for completion in 2028, three years ahead of the original 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.

Funding

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 approximately $2 billion from four sources: 1) $1.6 billion from the Connecting Washington funding package; 2) $130 million from local contributions; 3) $180 million from tolling; and 4) Federal grants.
