Coming in 2022: New roundabout at the intersection of SR 500 and NE 182nd Avenue in Clark County
WSDOT seeks public input to help inform highway closures during construction
WSDOT is planning to make improvements at the intersection of State Route 500 and Northeast 182nd Avenue by building a compact roundabout in summer 2022. Located in east Clark County, the intersection is situated along a curved stretch of roadway which makes it difficult to see the intersection or traffic ahead and has a speed limit of 50 mph. Crash data collected between 2013 and 2017 shows a history of crashes along this stretch of highway, most of which were rear-end or at-angle crashes. Increased growth and development over the last several years has resulted in an increase of travel through the area – about 10,000 vehicles travel along this stretch of roadway, daily.
A compact roundabout at this location offers the greatest safety benefit by reducing the potential for severe collisions, while keeping traffic moving through the intersection. Studies have shown that roundabouts are safer than traditional stop signs or intersections with traffic lights. The Federal Highway Administration also has determined that roundabouts can increase traffic capacity by 30 to 50% compared to traditional intersections.
Intermittent lane closures and a full closure of the SR 500 and Northeast 182nd Avenue intersection are required to build the roundabout. To minimize travel delays during construction we need your input
