Project overview

What is the SR 167 Master Plan, Planning and Environmental Linkages Study? 

The Puget Sound region is thriving and attracting large population and employment growth. This growth increases the strain on our transportation infrastructure and services, resulting in increased traffic congestion and increased needs for maintenance and preservation. There is a need to move people and goods by providing a multimodal transportation system that works now and into the future.  

As part of the SR 167 Master Plan effort, WSDOT has analyzed the study area, worked to understand the plans within the study area, and listened to the communities and partners to identify multimodal transportation needs, strategies, and solutions along the SR 167 corridor. The SR 167 Master Plan partners include tribal nations, counties, cities, ports, businesses, regional planning organizations, and transit agencies (King County Metro, Muckleshoot Tribal Transit, Pierce Transit, and Sound Transit).

The following timeline shows the study process next to the community and partner engagement. This online open house provides an overview of the multimodal scenarios and recommendation. The next step is to develop a final report.
