SR 503 Corridor Plan: Vancouver to Battle Ground

SR 503 is an important north-south link connecting Battle Ground, Vancouver and the surrounding communities in north and central Clark County. It serves residents and businesses along the corridor, carrying local commuters, freight, and regional recreational traffic. The corridor is growing increasingly urban and suburban as it experiences ongoing development through Battle Ground and Brush Prairie.

In 2019, between 19,000 and 32,000 vehicles used SR 503 every day. As the corridor continues to develop, WSDOT expects increased demand and growing delays at peak travel times. In light of this, WSDOT seeks to identify operational enhancements and transportation improvements that will benefit all users of the highway. 

The SR 503 Corridor Plan will focus on SR 503 and the surrounding areas from NE 99^th Street to NE 244^th Street/NW 25^th Street. The study team and its partners will:

• Review vehicle access along the corridor to determine whether it is too restricted or too unrestricted.
• Develop strategies for a connected and low-stress active transportation network for all.
• Consider industrial, commercial, and residential growth in the city of Battle Ground and north Clark County and its effects on congestion.
• Explore Practical Solutions and Transportation Systems Management and Operations (TSMO) strategies to maximize use of existing infrastructure.
• Determine Transportation Demand Management, transit, and other TSMO strategies to provide mobility, access, and congestion relief.
• Improve corridor safety.
• Identify equity and environmental justice issues and determine strategies to address them.
