We worked with representatives from local city, county, regional and state agencies to develop a route development plan for SR 164 between the cities of Auburn and Enumclaw. The plan includes a list of recommended projects that address safety and congestion issues along the corridor.

How Much Will the Improvements Cost?
Many of the improvements recommended in the SR 164 route development plan project list have not been considered in sufficient detail to allow for development of a usable cost estimate. Even before accounting for inflation, the total cost of the projects (if they were built today) would be well in excess of $200 million dollars. Under the current highway improvement budget, we would be able to build very few if any of the identified projects in the foreseeable future.
The corridor plan identifies existing and future roadway conditions and evaluates potential transportation improvements to improve roadway safety.
Recommended projects address traffic bottlenecks and chokepoints to improve the flow of people and goods through the corridor.
| Protects Environment
Proposed projects will maintain or improve air quality, protect or enhance fish-bearing streams and wetlands, and support regional environmental goals.
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 and Enumclaw
Organizations and groups: Muckleshoot Tribe and Puget Sound Regional Council
The study was funded through the following funding source:
- 2004 Legislative Appropriation - $650,000
