We are pleased to announce that the SR 410/Traffic Avenue interchange is fully designed and fully funded.  We’re now in the permit stage and plan to go out to bid this spring for construction.

Funding Partners

Please help us in thanking the many partners who came together to fund this project:

  • Transportation Improvement Board (TIB)
  • Puget Sound Regional Council – Surface Transportation Program (2 separate appropriations)
  • Sound Transit
  • Freight Mobility Strategic Investment Board
  • Port of Tacoma (2 separate appropriations)
  • Knutson Farms
  • State of Washington (2 separate appropriations)

The Solution

Reconfigure two intersections and add travel lanes plus multi-modal lanes across SR 410 to streamline the movement of vehicles, freight, pedestrians and  bicycles safely and efficiently while encouraging ridership on Sound Transit and support for South Sound businesses.

Project budget is approximately $17 million.

The Project

Improve capacity & safety on State highway system

  • Backups from this intersection impact traffic on SR 167, SR 512 and SR 410.
  • The alternate for freight is 24th Street interchange with SR 167, but that highway is now congested for over five hours each day.
  • Sumner’s Fire Station is in the congestion caused by this bottleneck, affecting responses to the highways and throughout the town.

Thriving State-wide Economy

  • This bottleneck is a primary route for freight mobility to/from Port of Tacoma.
  • Amazon.com and Costco are industry leaders who located major distribution centers in Sumner. In 2016-2017, they were joined by Penny’s Salsa, Helly Hansen, and Cummins.

Invest in Multi-Modal Transit

  • Increased access to Sumner’s Station reduces cars on already congested freeways, not to mention emissions.
  • Bikes and pedestrians avoid the current area, creating an implied barrier between Sumner and Puyallup, and between the station and trail system.
