CLARKSTON SPIRAL ROUNDABOUT

What began with the North Clarkston Circulation Study in 2014 has finally come full circle—literally. The long-anticipated Clarkston Roundabout is open to traffic!

Keller worked with the City of Clarkston and stakeholders to transform a complex five-leg signalized intersection into a spiral roundabout that improves safety and traffic flow in one of the busiest parts of the community.

This project followed the federal process, and was funded through the Surface Transportation Program, and follows Washington State Department of Transportation requirements and federal guidelines. Stakeholder and property owner coordination continued throughout the construction of the project. This project also included new ADA facilities for the entire intersection, upgraded lighting, signage, and more. The Keller team has been involved in every step of development, providing planning, design, ROW phase services, stakeholder coordination, and construction engineering services.
