The Washington State Department of Transportation (WSDOT) has awarded a contract to WSP | Parsons Brinckerhoff to serve as program manager for the Puget Sound Gateway Program.

This program will provide the missing highway network segments of Washington’s State Route 167 in northern Pierce County and SR 509 in southern King County, which will link the state’s largest ports to distribution and industrial centers in the Central Puget Sound region and to Eastern Washington. It will provide connectivity to the new southern access to Seattle-Tacoma International Airport and will support local community and economic development with improved linkages among the region’s manufacturing/industrial centers and urban centers.

The Gateway North Project (SR509) will extend SR 509 2.5 miles southward, and is intended to connect to I-5 with new access connections into the Green River Valley and to improve I-5 to Federal Way.

The Gateway South Project (SR 167) will extend SR 167 four miles westward to connect with I-5, and continues as the SR 509 Spur to connect with SR 509 near the Port of Tacoma.

As program manager, WSP | Parsons Brinckerhoff will assist WSDOT with strategic planning, program management, project controls, government relations, communications, technical coordination and consistency, quality assurance and quality control, and grants and agreements. The firm will develop and implement a public outreach program that will seek input from stakeholders within the business community and the public.

Construction on the new corridor is expected to commence in 2019.
