Status

July 2014

  • There will be occasional stops for 10 minutes or less throughout the day between 9 a.m. and 2 p.m. as needed for misc. work items.
  • WSDOT hosted a ribbon cutting ceremony to celebrate the extraordinary cooperation by multiple jurisdictions on this project. The two new roundabouts are near completion. View photos of the ribbon cutting ceremony here. You can also view photos of the groundbreaking ceremony here.

Overview
This ongoing 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.

The roundabout designs at these two intersections are meant to reduce the frequency and severity of collisions as well as improve traffic flow in the area. For more information on the benefits of roundabouts ...

The End Result
In this project, crews are constructing 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?
Construction begain in the summer of 2013.  Work is scheduled to be complete in summer 2014.
