Route description

SR 102 begins as the two-lane Dayton Airport Road at an intersection with the Washington Corrections Center access road and travels northeast into a heavily wooded area.[3] The highway turns east and passes the Washington State Patrol Academy before ending at an intersection with US 101 north of Sanderson Field and west of Turtle Lake.[4][5][6] The entire highway is located northwest of Shelton in unincorporated Mason County.[7]

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 average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that between 2,000 and 4,100 vehicles per day used the highway, mostly at the US 101 intersection.[8]

History

Major intersections

The entire highway is in Mason County.
