WSDOT has contracted with a consultant, Parametrix, to complete the final design and to develop the contract plans and special provisions for project advertisement.
Preliminary design work is underway for this project. The lane configuration and placement of the proposed roundabouts is being finalized.
WSDOT is working with property owners to acquire the additional right-of-way necesary to construct the project.
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.
View the proposed new roundabouts.
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.
