SR 510 - Meridian Rd SE - Roundabout and Paving

Project news

  • Crews have opened a modern roundabout at the intersection of SR 510 and Meridian Road Southeast. 
  • This project also includes repaving SR 510 between Old Pacific Highway Southeast and Reservation Road Southeast. The paving will be done at night and will require one-way alternating traffic.
  • Advance information about construction is available at the Thurston County construction and travel updates webpage. 

Needs & Benefits

Safety is WSDOT’s number one priority. This intersection has been identified as a location with a history of collisions. A roundabout at this location offers the greatest safety benefit by reducing the potential for severe collisions, while improving connectivity along the corridor. Roundabouts move traffic through an intersection more efficiently and with less congestion.

Traffic approaching a roundabout yield rather than coming to a complete stop and waiting for a traffic signal. Other benefits include improved access onto Meridian Road Northeast and increased sight distance. 

How to use a roundabout:

  • Slow down before entering the roundabout.
  • Yield to traffic already in the roundabout. Wait for a gap and then enter the roundabout.
  • Use turn signals when exiting the roundabout.

New pavement will cut down on the cost of maintenance by reducing the risk of costly emergency work to fill potholes and repair cracks.
