SR 503 Corridor Study Online Open House

English  |  Русский  |  Español  |  українська


State Route 503 is a major north/south highway between the cities of Battle Ground and Vancouver, WA. Once a mostly rural corridor, communities along SR 503 have grown more suburban and even urban in areas over time and with continued development.

WSDOT is studying how people use SR 503 now and how continued growth could affect future use. Focus areas include addressing gaps in active transportation (e.g., biking, walking, 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 SR 503 users and nearby communities.
