SR 503-NW Onsdorff Boulevard Intersection Improvements
SR 503-NW Onsdorff Boulevard Intersection Improvements
Overview
SR 503 and NW Onsdorff Boulevard is currently a 4-legged signalized intersection. This intersection connects two roads that are critical links between north and south county areas as well as east and west Battle Ground.
In 2018, the City began collecting concurrency mitigation fees to fund improvements needed to enable the intersection to support the traffic demand, or concurrency. An alternative analysis and intersection type evaluation will be completed to identify the appropriate intersection improvement. A signal and a roundabout option will be analyzed as the potential intersection improvement alternatives per Washington State Department of Transportation (WSDOT) requirements.
Funding
Battle Ground will use local funds to complete design, permitting, and to secure the necessary property right of way for this project. The city is currently working to obtain funding for the construction phase of this project, so the budget and schedule for this portion of the project is yet to be fully determined.
Project Timeline
This project is currently undergoing preliminary engineering.

Design
Before the intersection design is determined, the project will first undergo an alternative analysis. This analysis involves the forecasting of the future demand for the base model and the testing of various project alternatives to determine the optimally performing solution. Factors such as (but not limited to) traffic safety, transportation standards, and geographical characteristics will be considered when determining the final design.
