Every year, the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of annual average daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that between 2,300 and 5,800 vehicles per day used the highway, mostly in the Montesano area.{{cite web |author=Staff |year=2011 |title=2011 Annual Traffic Report |publisher=Washington State Department of Transportation |url=http://www.wsdot.wa.gov/mapsdata/travel/pdf/Annual_Traffic_Report_2011.pdf |access-date=February 14, 2013}}
