SR 503 Corridor Plan: Vancouver to Battle Ground

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.

February 2022 - Summer 2023
In progress


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.   

Earlier this year, WSDOT hosted an online open house to gather input from people who use this corridor. The ideas and comments received will be considered in the development and refinement of future improvements and investments that will benefit and support travelers of all modes and abilities for many years to come.  

WSDOT is conducting a planning study of State Route 503, between the cities of Vancouver and Battle Ground, in Clark County, to determine how current and future growth of the area impacts travelers, businesses and residents who use this stretch of highway. The SR 503 Corridor Plan will focus on SR 503 and the surrounding areas from NE 99th Street to NE 244th Street/NW 25th Street.
