SR 167 - 8th to 277th Southbound HOT Lane - Complete December 2016

The SR 167 HOT lane extension is open to tolled, single occupancy vehicles as of Dec. 17, 2016.

This project widened SR 167 to add a lane in the southbound direction and extend the existing High Occupancy Toll (HOT) Lanes system south on SR 167 in the Green River Valley. Expanding the successful 9-mile SR 167 HOT lanes connects King and Pierce County communities to vital employment hubs in the Puget Sound area.

Extending the southbound HOT lane from its existing end point at 37th Street Northwest in Auburn to Eighth Street East in Pacific will reduce congestion and improve mobility, traffic flow and safety on SR 167.

Why is WSDOT building this project?
The project will provide congestion relief for commuters in the southbound direction, particularly in the afternoon rush hour. 

The End Result
This project extended the southbound HOT lane from south of 37th Street Northwest in Auburn to Eighth Street East in Pacific.

The project will provide congestion relief for commuters and freight carriers, improve safety, and provide commuter options. When it opens, the project will also maintain fast, toll-free trips for HOV users (transit, vanpools, carpools, and motorcycles).

Project Benefits

  • Safety:  Safety features include updated elements such as new guardrail, pavement striping, drainage improvements, illumination and signage.
  • Congestion relief: Extending the HOT lane further south will ease congestion and provide a smoother commute for drivers.  It will be especially helpful for southbound commuters heading home during the evening commute.
  • Environmental Benefits: Crews built stormwater facilities and a floodplain storage site to collect and filter roadway runoff before it released into area streams and wetlands, improving water quality for salmon and other wildlife. They also upgraded culverts in the project area to improve fish passage.
