Both southbound lanes SR 503 will be closed overnight for paving work from 9 p.m., Monday, Aug. 29 to 5 a.m., Tuesday, Aug. 30
VANCOUVER – Travelers who use State Route 503, also known as Northeast 117th Avenue, in northern Clark County, will need to plan ahead for possible overnight delays.
On Monday (Aug. 29), the Washington State Department of Transportation maintenance crews will close the southbound lanes of SR 503 between Southwest 40th Street and Caples Road, to repave a portion of the highway.
Paving work smooths the roadway surface for drivers and extends the useful life of the highway for many years to come.
What to expect when paving work starts
- Both southbound lanes SR 503 will be closed overnight for paving work from 9 p.m., Monday, Aug. 29 to 5 a.m., Tuesday, Aug. 30.
- During the overnight closure, travelers on southbound SR 503 will follow a signed detour using Southwest 40th Street to Northeast 179th Street and continuing onto Northeast 122nd Avenue/Northeast Caples Road, then back onto southbound SR 503.
As with any highway maintenance and construction project, travelers must exercise caution through the work zone. Traveling at slower speeds, having patience and obeying warning signs and flagging personnel instructions benefits all users of the roadway and ensures everyone’s safety.
