History

An unpaved road connecting the Manson area to Chelan was built in the 1890s after the establishment of Chelan in 1886, with an extension of the road to Chelan Falls was built in 1919 to connect to the newly dedicated

. During the formation of the Primary and secondary state highway system in 1937, the route from Manson to Chelan became SSH 10C, ending at US 97, and the route from Chelan to Chelan Falls became a segment of SSH 10D, beginning at US 2 in Orondo and traveling north to US 97. During the 1964 highway renumbering, SSH 10C became SR 150 and SSH 10D became SR 151. US 97 was re-routed onto the former route of SR 151 towards Chelan Falls in 1987, proposed in the 1950s, and SR 150 was extended to the new bypass of Chelan. U.S 97 Alternate was created on the former route of US 97, becoming
