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, in addition to the feasibility of a bypass for SR 164.

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 problems to improve the flow of people and goods through the corridor.
