It runs southeasterly for 31 miles (50 km) in the Eastside region of King County, connecting Woodinville, Redmond, Fall City, and North Bend.

The highway travels along the western end of Education Hill and turns due south onto 164th Avenue NE while approaching downtown Redmond.

[5][8] SR 202 continues into unincorporated King County, traveling east and south around the Sammamish Plateau by following the course of Patterson Creek.

The highway continues southeast along the Snoqualmie River, passing Fall City Airport and crossing Tokul Creek via a long hairpin turn.

The highway turns southwest onto Bendigo Boulevard and travels through the city's downtown, exiting via a crossing of the South Fork Snoqualmie River.

SR 202 passes the North Bend Premium Outlets mall and intersects I-90, where it terminates at a partial dumbbell interchange.

[35] Since the early 2000s, the Washington State Department of Transportation (WSDOT) has built several roundabouts on SR 202 in Woodinville,[4] Snoqualmie,[36] Fall City,[37] and North Bend,[38] in an effort to improve the road's safety as traffic increases along the corridor.

[40] In 2007, WSDOT also studied possible improvements to SR 202 in the Sammamish area, recommending the construction of new lanes, traffic signals, guardrails, and other projects.

[41] The study's recommended projects would cost an estimated $52.9 million to complete, and were not funded by the state government.
