Secondary State Highway 10D

SSH 10D was added to the state highway system in 1937. This highway began at Jct PSH 10 (US 97, now Alt US 97) in Chelan and headed southeasterly to Chelan Falls, crossed the Columbia River to Beebe, and continued southerly, ending at Jct PSH 2 (US 10, now US 2) at Orondo. A branch of SSH 10D beginning a few miles NE of Chelan and extending south to Chelan Falls was added to SSH 10D in 1959. When the current state highway numbering system was first posted in January 1964, SSH 10D became signed as SR 151. SSH 10D Spur became SR 151 Spur.
