WSDOT and the SR 167 Corridor Working Group have completed the SR 167 Valley Freeway Corridor Plan which contains a list of recommendations to improve safety and relieve congestion on 27 miles of SR 167 between Renton and Puyallup.
Why Did WSDOT Undertake the SR 167 Corridor Plan?
The last few decades have transformed the Green River Valley from farmland to a mix of busy residential, commercial, retail and industrial activity. Unfortunately, increasing development often brings an increase in traffic congestion and collisions. If current trends continue and no investments are made by 2030, the time to drive the corridor could go from an average of 20 minutes to over an hour.
The corridor plan identifies projects to improve freeway ramps. Improving ramps will enhance safety and truck mobility by providing more room for vehicles to gain speed or slow down when entering and exiting SR 167.
The corridor plan identifies improvements that respond to growth and economic development. Extending merges and adding lanes will allow SR 167 to carry more people and vehicles as the region continues to grow.
| Protects Environment
Proposed projects will maintain or improve air quality, protect or enhance fish-bearing streams and wetlands, and support regional environmental goals.
| Economic Incentive
The recommendations include special considerations for freight which play a a vital role in our region’s economy. Recommendations include reducing roadway curves and lengthening on-ramps at key locations to provide additional time and space for large trucks to gain speed and merge into traffic more easily and safely.
Partnerships & Cooperation
This study represents a shared plan between WSDOT and local partners.
We sought input from local communities to learn more about the safety and mobility problems they are encountering and to document their ideas for solutions. We also worked with a corridor working group made up of representatives from the following local cities, counties, agencies, groups and organizations:
Cities: Auburn; Algona; Edgewood; Kent; Puyallup; Renton; and Sumner
Counties: King and Pierce
Agencies: Sound Transit; King County Metro; and Washington State Patrol
Organizations and groups: Muckleshoot Tribe; Port of Seattle; Port of Tacoma; and Puget Sound Regional Council
- Total Funding - 2003 Gas Tax $9.6 Million
