List of former state routes in Washington

For a list of current state highways, see List of state routes in Washington.

Since the 1964 state highway renumbering, which established the current state route system, the Washington State Department of Transportation has decommissioned some state routes. Once a highway has been decommissioned, the highway is turned over to the local county or city that it is in, they are then responsible for all maintenance on the former highway. All former highways are codified in Washington law under the Revised Code of Washington, chapter 47.17, section 420.^{[citation needed]}

SR 901 was created in 1964 from Secondary State Highway 2D. At the time of its creation, SR 901 began at the intersection of Lake Washington Boulevard and State Route 520, on the border of Kirkland and Bellevue. It then traveled north along Lake Washington Blvd. to downtown Kirkland. At the intersection of Lake St. and Central Way, SR 901 turned right, traveling east along Central Way. It then continued as Redmond Way into Redmond turning south onto West Lake Sammamish Parkway when the roads intersected. It then followed West Lake Sammamish Parkway into Issaquah, ending at its intersection with State Route 900. SR 901 also had a spur leading from West Lake Sammamish Parkway into downtown Redmond along Redmond Way.^{[citation needed]}

In 1971, SR 901 was broken into two parts. The western part, from SR 520 to the intersection of Redmond Way and West Lake Sammamish Parkway (including the spur into Redmond), was renamed State Route 908.

Effective April 1, 1992, SR 901's path was changed again; now it ran through the city of Sammamish along East Lake Sammamish Parkway from Front Street in Issaquah to State Route 202 east of downtown Redmond.
