Project overview
Crews will create a new route for SR 3 while maintaining the existing state highway through Belfair as a business loop. The proposed 6-miles of new highway would provide a new option for drivers to travel around and not through Belfair. The new portion of SR 3 is a Limited Access Corridor. A Limited Access Corridor restricts the total number of intersections. The restriction benefits through-travelers by shortening travel times due to reduced slowing or stopping traffic.
What to expect
Construction has not yet started. The environmental assessment is complete and the Federal Highway Administration has issued a Finding of No Significant Impact (FONSI) for this project.
SR 3 Belfair Freight Corridor proposed alignment
State Route 3 in Belfair regularly experiences congestion during peak commute hours, especially as numerous drivers stop and make turns. Heavy congestion has the potential to negatively affect emergency response times and economic vitality. This project would improve travel times for regional traffic, reduce the volume of regional traffic in Belfair, and help reduce the potential for collisions.
WSDOT has completed its supplemental environmental assessment (SEA). The entirety of the SEA and its individual discipline reports are linked in this section.
