The DRAFT SR 167 Corridor Plan recommendations are available
online.
Overview
State Route 167 is a primary highway connecting south King and north Pierce counties to the Seattle/Bellevue metropolitan area. The corridor serves a growing number of housing developments and lies along the largest freight distribution center in the region. SR 167 is also an important alternative route to I-5 for moving both people and goods in the Puget Sound Region.
SR 167 Valley Freeway Corridor Plan Draft Recommendations
The Washington State Department of Transportation and the SR 167 Corridor Working Group have completed the draft recommendations to improve safety and relieve congestion on 27 miles of SR 167 between Renton and Puyallup. The draft recommendations are part of the SR 167 Valley Freeway Corridor plan report, which is expected to be published in early 2009.
A corridor plan is the first step toward obtaining funding for transportation improvement projects. It identifies existing and emerging problems, and proposes specific solutions to be implemented over the next 25 years.
The SR 167 project team examined the effects on traffic and the environment of adding one to two additional lanes and examined projects that would provide near-term relief by addressing specific bottlenecks where traffic bogs down. Completing the HOV lanes is a priority that was analyzed, along with HOT lanes as a way to move more vehicles more efficiently.
To identify problems and solutions, we examined:
- Collision rates and locations
- Population growth and future development
- Traffic flow
- Environmental issues
- Future demand, costs and ability to pay for improvements
- Public input
Why is WSDOT
looking at ways to improve SR 167?
The last few decades have transformed the Green River Valley from farmland to a mix of busy residential, commercial, retail and industrial activity. Between 1980 and 2000, population grew by 68% and is projected to grow another 39% by 2030.
Employment has nearly doubled between 1980 and 2000 with growth projections of another 50%. This could mean another 90,000 jobs in the Valley by the year 2030, which is good news. However, increasing development often brings an increase in traffic congestion and collisions.
A corridor that carried 15,000 vehicles per day in 1970, now carries 120,000 vehicles on a busy weekday. If current trends continue and no investments are made by 2030, southbound travel time on the corridor could go from an average of 20 mins. to over an hour.
The End Result
The SR 167 Corridor Plan was undertaken to provide a list of improvement projects for the corridor that can be built in stages over the next 20-30 years. One project is already underway: building southbound HOV/HOT lanes from Auburn to Pacific, a high-priority project of the plan.
When finalized, the corridor plan’s recommendations will be incorporated into other regional and statewide plans to ensure consistency and give decision makers the tools they need to prioritize projects for implementation. The corridor plan will also give local leaders an agreed-upon list of projects to take to the legislature for future funding. Other projects in the plan will be built as they are funded.
Project Benefits
- Safety - The corridor plan will identify 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.
- Congestion Relief - The corridor plan will identify 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.
- Environment - Proposed projects will maintain or improve air quality, protect or enhance fish-bearing streams and wetlands, and support regional environmental goals. For more information, please read the "Environmental Protection" paragraph below.
What is the project timeline?
The study began in August 2005 and will be complete by Winter 2007/2008.
Financial Information
The corridor plan and some SR 167 projects are funded by the following sources:
- 2003 Gas Tax - $9.6 Million
- Total Funding Available from all sources - $9.6 Million.
