SR 167 Completion Project - Project Map

A map of the stages of the SR 167 completion project area.

Project Highlights

1. Tolling SR 167
WSDOT will toll all lanes on the new portion of SR 167. WSDOT will collect tolls using all electronic tolling at two toll points. There will be no tollbooths. The Washington State Transportation Commission will set toll rates by time of day – more during peak periods and less during mid-day, evenings and weekends. Toll rates for the new portion of SR 167 have not been determined. The Legislature authorized tolling on this corridor in the 2019 session. The Washington State Transportation Commission will oversee the rate-setting process, which will begin closer to when the project is completed. The Legislature directed $95 million from tolls will be used to construct the SR 167 Completion Project.

2. Working with Sound Transit
WSDOT is coordinating closely with Sound Transit on the Tacoma Dome Link Extension project as both agencies work to build new major infrastructure projects in the area.

3. Riparian Restoration Program (RRP)
The RRP is a watershed strategy for stormwater management that will use an innovative approach to conventional flow control facilities. It will reduce flood levels, improve degraded stream and riparian corridor habitat, and provide benefits to fish and wildlife.

4. Diverging Diamond Interchange (DDI)
For this project WSDOT will construct the state’s second Diverging Diamond Interchange (DDI). The DDI will function as an on and off ramp to I-5. The unique design has fewer conflict points than traditional interchanges, which improves traffic safety.

5. Single Point Urban Interchange (SPUI)
A single point urban interchange (SPUI) will be built at the new interchange between SR 167 and SR 161. These interchanges accommodate high traffic volumes and only use one traffic signal to control all the movements at the interchange.
