The construction phase is starting on the final missing pieces of two major state routes in King and Pierce counties.
What's known as the Puget Sound Gateway Program includes two major projects: The completion of SR 167 in Pierce County and SR 509 in King County.
The final four miles of SR 167 will be built between Meridian Road in Puyallup and I-5 in Fife. The project also includes a two-mile connection from I-5 to the Port of Tacoma.
The new segment will have two general purpose lanes in each direction between Puyallup and I-5, and one lane in each direction between I-5 and the Port of Tacoma.
In King County, SR 509, which currently ends at South 188th Street, will be extended to I-5. The extension will have two lanes in each direction. A new interchange will be built at S. 188th St.

The Washington State Department of Transportation said extending 509 will serve as an alternative to I-5, SR 99 and local streets. It will also create a new southern access point to Sea-Tac Airport.
“By completing SR 167 and SR 509, we are closing two of the state’s major transportation gaps. But these aren’t just WSDOT projects,” said Secretary of Transportation Roger Millar. “Eighteen local jurisdictions want to see these projects completed and have shown their support by contributing $130 million towards their construction.”
Both projects are expected to be completed in 2028.
