State Route 102 (SR 102) is a 2.86-mile-long (4.60 km) state highway serving the Washington Corrections Center and Washington State Patrol Academy in the U.S. state of Washington. The highway extends northeast and east as Dayton Airport Road from the Washington Corrections Center through rural Mason County to an intersection with U.S. Route 101 (US 101) northwest of Shelton. SR 102 was established in 1984 on an unpaved roadway that was built by the 1950s.

Route description edit

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. The highway turns east, passing the Washington State Patrol Academy and The Ridge Motorsports Park, before it ends at an intersection with US 101 north of Sanderson Field and west of Turtle Lake. The entire highway is located northwest of Shelton in unincorporated Mason County.^[3]

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 2,000 and 4,100 vehicles per day used the highway, mostly at the US 101 intersection.^[4]
