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.

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.
