WSDOT maintenance crews will remove brush and clear danger trees alongside SR 503 near Amboy
CLARK COUNTY – Travelers in both directions of State Route 503 in Clark County should expect delays.
Beginning Monday, July 21, the Washington State Department of Transportation maintenance crews will remove brush and clear danger trees alongside SR 503 near Amboy. This work improves visibility, lowers the risk of fires, and keeps plants from growing onto the road.
