WSDOT and the consultant design team are finalizing the project design and contract documents. The project is scheduled for bid advertisement this coming spring.
WSDOT is working with utility companies to relocate facilities that will be impacted by the project.
WSDOT is completing appraisals and working with property owners to acquire additional right-of-way to accommodate the footprint of the new roundabouts.
Overview
A new project on SR 510 will reduce the potential for collisions and improve traffic flow for Thurston County motorists by building roundabouts at the intersections of SR 510 with Reservation Road and Yelm Highway.

Why is WSDOT
building roundabouts on SR 510 at the intersections with Reservation Road and Yelm Highway?
These intersections experience a high rate of collisions and congestion during peak hours. Reconfiguring these intersections as roundabouts has a high potential for reducing the frequency and severity of collisions and improving mobility.
WSDOT, Thurston County and the Nisqually Indian Tribe completed an Intersection Alternatives Study in 2011. This study found that constructing roundabouts at these two intersections would provide the most effective solution.
WSDOT has initiated the design for a roundabout at each of these intersections that will reduce the frequency and severety of collisions as well as improve traffic flow in the area. For more information on the benefits of roundabouts ...
The End Result
this project will construct roundabouts at the Yelm Highway and Reservation Road intersections. SR 510 roundabouts will be connected with a four-lane highway.
Project Benefits
Our goal is to make safety improvements that will help reduce the potential for injury and fatal collisions, help improve safety, and reduce congestion.
What is the project timeline?
The project is currently in the final design phase. The project will be advertised for bids the spring of 2013, with construction beginning this summer. The new roundabouts are scheduled to be open to traffic by the fall of 2013.
