1920s, and was incorporated into the Seattle–Fall City branch of the Sunset Highway (Primary State Highway 2) in 1937. After the opening of the North Bend bypass in 1941, the branch highway was extended to North Bend over the former Sunset Highway. In 1963, the Washington State Legislature commissioned a new state highway numbering system to ease confusion over similarly-numbered routes. The new system debuted in 1964, assigning State Route 522 (SR 522) to the Seattle–Bothell–North Bend highway, and State Route 202 (SR 202) to a proposed branch of the Stevens Pass Highway between Monroe and Bothell. By 1970, SR 522 was moved to the completed Bothell–Monroe highway, retaining the Seattle–Bothell portion, while SR 202 was designated to the remaining highway from Woodinville (east of Bothell) to North Bend. SR 202 was extended southwest of downtown North Bend to a new interchange with I-90 in 1978, after it was moved to a freeway bypass of North Bend. The area around the new interchange was annexed by the city of North Bend prior to the opening of the I-90 bypass, and a factory outlet mall opened at the interchange in 1990. Since the early 2000s, the Washington State Department of Transportation (WSDOT) has built several roundabouts on SR 202 in Woodinville, Snoqualmie, Fall City, and North Bend, in an effort to improve the road's safety as traffic increases along the corridor. Another section of SR 202 between Redmond and Sammamish was widened in 2008 to accommodate additional traffic and included the construction of a new flyover ramp at the SR 520 interchange. 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. The study's recommended projects would cost an estimated $52.9 million to complete, and were not funded by the state government.
