Golden Given Road East / 99th Street East (CRP 5887)

What’s Happening
Engineering: Initial work on the preliminary engineering for the project began in March 2021. County crews surveyed the project area, and we started to evaluate conceptual layouts.

About the Project
Planned improvements to this intersection include a new urban compact roundabout with mountable center and splitter islands, crosswalks, streetlighting, and cement concrete curb and gutter. Also to be considered are pervious concrete sidewalks and Rectangular Rapid Flashing Beacons (RRFB) at the new crosswalks, as well as storm drainage treatment facilities.

Why A Roundabout?

While some drivers are initially hesitant about driving roundabouts, studies show that after driving a roundabout, most people favor them over a traditional traffic signal.


Studies have also shown that roundabouts are safer than traditional stop signs or signal-controlled intersections because they require drivers to slow down to maneuver through the intersection.


At intersections with relatively lower traffic volumes, urban compact roundabouts like the one planned at Golden Given Road East / 99th Street East can reduce, or avoid altogether, the additional right-of-way needed from normal roundabouts. Insurance Institute for Highway Safety (IIHS) and Federal Highway Administration (FHWA) studies have shown that roundabouts typically achieve:


  • A 37 percent reduction in overall collisions.
  • A 75 percent reduction in injury collisions.
  • A 90 percent reduction in fatality collisions.
  • A 40 percent reduction in pedestrian collisions.

Resources on Roundabouts

The Washington State Department of Transportation (WSDOT) has a fantastic web page, Roundabout Information. This web page is devoted to explaining all things "Roundabout" including a couple of brochures, references to some studies, and several videos on various roundabout related topics.

Project Timeline

March 2021 to March 2024: Complete the field survey, soils studies, preliminary engineering and right-of-way plans.


March 2024 and Beyond: A schedule for completion of final engineering, permitting, right-of-way acquisition, and construction will be determined during the preliminary engineering phase currently underway.
