Public involvement

Your thoughts and opinions are important to us. WSDOT will host an open house, during the design process to share information and receive input from the public. WSDOT will continue to inform the public of any future public involvement through this Web page, the SW Region's Public Involvement page, and through the local media.

Increasing safety is our priority

This project will improve safety by reducing the severity of accidents where motorists have driven off the roadway.

Environmental protection

The necessary environmental analysis for this project is underway. This analysis will document the project’s environmental impacts (natural, ecological, societal and economic) in order to guide the final design and construction. This project will provide mitigation for impacts to the environment, with stormwater treatment being the primary mitigation expected.

For environmental information specific to this project, please contact Barb Aberle at (360) 905-2186, or e-mail

Will this project impact tribal resources?

At WSDOT we seek to address the concerns of the tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.

This process is not applicable because the project does not impact tribal lands.
