What’s the latest on the new SR 3 highway in Belfair?

By Mark Krulish

Residents and commuters alike know about the traffic challenges we have in downtown Belfair on State Route 3. Rush hour traffic clogs up the roadway. Drivers making turns on and off the highway slow down the flow of vehicles. The jams can also affect emergency response times.

We have been working on a project for a few years that will be a great benefit to Belfair – a new freight corridor through the area intended to ease traffic on the main route through the area.

In fact, the SR 3 freight corridor is among only a handful of new roadways that are planned in the entire state.

We understand this idea for a new highway around Belfair has been around for a long time. We also know many folks are wondering when the road will finally be built. We expect construction to begin in 2026 – roughly two years later than first announced – with the road opening in 2028.

A look at the proposed new highway in Belfair

Reason for later than expected start date

As part of the Move Ahead Washington funding package, the project will include two more roundabouts. The connections on these roundabouts will allow for new local roads to be built in the future by Mason County. Adding these improvements to the project means we need more time to work on the design and environmental compliance, to ensure the project looks at Complete Streets.

We fully understand some will be disappointed by this news. Please know that building a new state route is a methodical process with many requirements that need to be met. The addition of two roundabouts requires work that will extend the process.

Although these new improvements represent a later than expected timeline, the good news is the Move Ahead Washington and Connecting Washington funding coming from the state legislature ensures the lion’s share of this project, including some new improvements, is funded.

Two new roundabouts at the end of the new Belfair highway will connect to SR 302 and reconnect to SR 3.

The main elements of the project have not changed. We plan to build a new 6-mile, two-lane alternate route parallel to SR 3. A roundabout connects the new road at the north end with Southwest Lake Flora Road in Kitsap County. At the southern end, two roundabouts will be built near North Mason High School. One connects the new roadway with SR 302 and the other brings the road back to SR 3. The single-lane roundabouts are built to accommodate vehicles of all sizes with a low, drivable curb on the center island.

The new highway will allow travelers to have a quicker ride through Belfair. There are few intersections, which shortens travel time and reduces slowing or stopping traffic.

This is a complex project with many moving parts. We know regular users of SR 3 through Belfair are hoping for relief from the daily congestion. We’re thankful for your patience as we work to bring this project to life.
