Project Overview

What is the Gateway Program?

The SR 167 Completion Project is part of the Puget Sound Gateway Program, which also includes the SR 509 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 State Route 167 and State Route 509 Completion projects under one program allows WSDOT to maximize efficiencies in planning, environmental review, design, and construction.

Check out our Gateway Program video to learn more about the Program and the details of its projects.

What is the SR 167 Completion Project?

State Route 167 is the primary highway connecting the Kent and Puyallup River valleys to the Seattle/Tacoma/Bellevue metropolitan areas. The original planned route for the highway ran from Renton to Tacoma, but construction halted near Puyallup before reaching Tacoma in the 1980s.

The SR 167 Completion project will build the remaining six miles of SR 167 between North Meridian Avenue (SR 161) in Puyallup and SR 509 near the Port of Tacoma. In addition, the project also includes safety improvements at interchanges with local roadways, significant investments in climate resiliency through wetland and stream restoration, and multi-modal access including the Tacoma to Puyallup Regional Trail.

Project Timeline

The SR 167 Completion Project will be completed in three construction stages.

Stage 1a, completed in Summer 2022, built a new four-lane bridge over Interstate 5 in Fife, a new multi-lane roundabout connecting the new Wapato Way East bridge to SR 99, and improvements to the Interurban Trail. Stage 1b (also known as the SR 167, I-5 to SR 509 New Expressway Project) is the focus of this open house and began construction in July 2022. Stage 2 is currently scheduled to begin construction in late 2024. The whole project will be open to traffic by 2028.

Stage 2 is nearing the end of its conceptual design phase, with the team preparing documents that will inform contractor bidding in 2023. Stage 2 construction activities are scheduled to begin in late 2024 and end by 2028.

The contractor began construction on Stage 1b in July 2022. This work will take about four years to complete.

SR 167 Stage 1b Construction Overview

The SR 167, I-5 to SR 509 New Expressway Project (Stage 1b) includes the following improvements:

  • A new two mile tolled expressway that will link Interstate 5 to State Route 509 near the Port of Tacoma. 
  • New interchanges at I-5, 54th Avenue and SR 509.
  • A new 2.5 mile shared-use path from SR 99 to SR 509 with connections to Alexander Avenue East and Taylor Way East.
  • The first half of a new diverging diamond interchange (DDI) over I-5 connecting the interstate to the SR 167 Expressway.
  • New sidewalks and widening of SR 99 from the new roundabout through the existing 70th Avenue East intersection.
  • Approximately 150 acres of wetland and stream restoration and improvements.
The SR 167, I-5 to SR 509 New Expressway project is the second of three construction stages for the SR 167 Completion Project.
