By the 1850s, Emigrant Pass, slightly south of OR 58's crossing at Willamette Pass, was being used by emigrants to the Oregon Territory as a way over the Cascades. In October 1853, a party of 1,500 was almost stranded at the pass, but was saved from a Donner Party-style tragedy by nearby settlers who had begun to improve the route up the Middle Fork Willamette River earlier that year as a shortcut between the Oregon Trail near Boise, Idaho, and the Willamette Valley.
