Washington State Route 902
State Route 902 (SR 902) is a long state highway located entirely in Spokane County, Washington, United States. The highway serves to connect Lakeland Village and Medical Lake to the county seat of Spokane. The highway has existed since at least 1931, and before the 1964 state highway renumbering, it was numbered Secondary State Highway 11D. Between 1,600 and 9,200 vehicles used the highway on an average day in 2009. Route description. SR 902 begins at exit 264, a diamond interchange, on the concurrent Interstate 90 (I-90)/U.S. Route 395 (US 395) in western Spokane County. The  road travels northwesterly through sparsely populated light woodlands, passing west of a small lake, before turning north. The highway then passes Lakeland Village, an educational facility for the mentally disabled, before reaching the city of Medical Lake. The highway passes through western Medical Lake and Medical Lake High School before turning east at Brooks Road. The highway passes over a rail line belonging to the Eastern Washington Gateway railroad, before leaving Medical Lake city limits. The road continues northeast, clipping the southern border of Fairchild Air Force Base before intersecting the concurrent I-90/US 395 at exit 272. Every year , 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 2009, WSDOT calculated that as few as 1,600 vehicles used the highway at the western terminus, and as many as 9,200 vehicles at the eastern terminus. History. The first roadway linking now I-90/US 395 and Medical Lake first appeared on maps in 1931. By the 1933 map, the remainder of the highway  was present, linking back to I-90/US 395. Before the 1964 state highway renumbering, SR 902 was numbered Secondary State Highway 11D, a branch of Primary State Highway 11, the predecessor to US 395 through the region. No changes have been made to the alignment of the roadway, however the legal definition of the highway was changed during the 1991 legislative session.
