To keep travelers moving during the closure, a temporary signal will be used at Northeast 88th Street and Ward Road

VANCOUVER – Travelers in east Clark County who use the intersection of Fourth Plain Boulevard, also known as State Route 500, and Northeast 182nd Avenue will need to plan ahead and find an alternate route in the coming days.

Beginning Thursday (Aug. 4), crews working for the Washington State Department of Transportation will close the intersection for 10 full days while they work to construct a roundabout.

Closure details

• Both directions of Fourth Plain Boulevard/SR 500 and Northeast 182nd Avenue will close from 3 a.m. Thursday (Aug. 4) and will reopen on Sun., Aug. 14.

To keep travelers moving during the closure, a temporary signal will be used at Northeast 88th Street and Ward Road. Travelers should slow down and expect delays through the area. 

A roundabout at this location was chosen to improve safety and reduce crashes, and will improve traffic flow within the intersection from all directions.

Further east and separate from this project, contractor crews working for WSDOT will be performing paving work along SR 500 between Northeast 28th Street and Northeast Robinson Road, Thursday, Aug. 4 through Saturday, Aug. 6. Travelers will alternate through a single lane with flaggers and follow a pilot car through the work zone.

To minimize delays travelers are reminded to plan ahead by signing up to receive construction updates. Real-time roadway and weather information is available 24/7 via the WSDOT mobile app or by following the Southwest Region Twitter account.
