SR 3 Roundabouts Pre-Design Study

Planning study news

Thank you for taking the time to learn about the SR 3 Roundabouts Pre-Design Study during the online open house. The project will now move forward into design. Construction is scheduled for June 2024.

Timeline
March - April 2022
Status
Complete
Budget
$1.5 to $2 million per roundabout (cost estimates are subject to change)

Purpose

WSDOT routinely reviews rural intersections on the state highway system to find ways to reduce potential crashes. We look for locations that are at the highest risk for severe crashes.

This project will construct single-lane roundabouts at the following Mason County intersections on State Route 3 at Deer Park:

  • East Agate Road
  • East Pickering Road
The study of the intersections on SR 3 examined the replacement of stop signs with a roundabout.
