What is the Gateway Program?
The SR 509 Completion Project is part of the Puget Sound Gateway Program, which also includes the SR 167 Completion Project. Together these projects will help truck traffic move more efficiently and ease congestion throughout the Puget Sound region. These improvements will enhance the state’s economic competitiveness, both nationally and globally, connecting the state’s largest ports to key distribution centers in King and Pierce counties.
Delivering the SR 167 and SR 509 Completion projects under one program allows WSDOT to maximize efficiencies in planning, environmental review, design, and construction.
