The SR 20 Discovery Road and Kearney Street Intersection Roundabouts Pre-Design Study is complete and the report is now available for viewing.

The Kearney Street roundabout was completed in 2024.
Planning study report
The existing signal systems on SR 20 at the Mill Road/Discovery Road and Kearney Street intersections in Port Townsend have reached the end of their useful life. They require frequent and extensive maintenance to keep them operational, and the signal heads are suspended on span wire instead of the preferred mast arms. WSDOT has proposed replacing the outdated signals at both locations with compact roundabouts that fit within the intersection for improved mobility, safety, and reduced maintenance costs.
