History

The roadway currently signed as SR 906 was assigned many route numbers over the years. The Washington State Legislature established State Road No. 2 in 1909 over Snoqualmie Pass (elevation 3,022 feet) and Old Blewett Pass (elevation 4,071 feet).[2][3] The first car crossed Snoqualmie Pass on State Road 2 in 1915.[4] State Road 2 was concurrently designated U.S. Route 10 in 1926. State Road 2 was designated Primary State Highway 2 (PSH 2) in 1937. By 1940, US 10 was realigned to close to present day I-90. When US 10 was realigned, the former US 10 was designated US Route 2. In 1964, PSH 2 was renumbered State Route 2.[5] US 2 would later be realigned to its current route over Stevens Pass. The federal government removed US 10 from the U.S. Route system after I-90 was built.
