Planning study news
Thank you for participating in the SR 3 Mason Lake Road Pre-Design. The pre-design is complete. The project has moved to a WSDOT design office to begin the design process.
Purpose
This pre-design sought feedback on a roundabout at the SR 3 and Mason Lake Road intersection.
In March and April 2025, WSDOT met with local agencies. In May 2025, WSDOT conducted an online open house. The purpose of this engagement was to gather feedback about the roundabout.
The report (PDF 1.5MB) with information about the pre-design, the recommended roundabout and feedback WSDOT received during the online open house is available.
Target Zero is WSDOT’s safety improvement program. It aims to reduce serious and fatal crashes on state highways. The program focuses on two aspects: crash Reduction and crash prevention.
Studies show that roundabouts are safer than traditional traffic signals or stop signs. They accommodate vehicles of various sizes. This includes emergency vehicles, buses, bicycles, semi-trucks with trailers, and farm and logging equipment.
WSDOT routinely reviews rural area intersections on its state highway system to find ways to reduce potential crashes. We analyze locations that are at the highest risk for severe crashes. Once we identify those intersections, WSDOT develops a plan to reduce crash potential.
