Planning study news
The Washington State Department of Transportation is conducting a corridor study to help inform future improvements and investments that will benefit and support all users of SR 503.
WSDOT is studying how people use SR 503 and how continued growth might affect future use. Focus areas include addressing gaps in active transportation (e.g., biking, walking and rolling) facilities, access to transit, vehicle traffic pain points, safety improvements and freight mobility planning. The study will result in the SR 503 Corridor Plan, a long-term vision for SR 503, with recommended improvements and investments to benefit users of SR 503 and nearby communities.
