 It runs mostly west to east across aspen parkland through Hairy Hill, turning north through Duvernay, Brosseau, Foisy, St.Brides, and east to St. Paul before ending at Highway 41 approximately north of Elk Point, concurrent with Highways 36 and 45 for lengthy sections.The route was established in 2006 when Alberta Transportation renumbered portions of Highways 637, 45, 860, 36, and 28 between Highways 15 and 41, forming a more coherent route between St. Paul and Edmonton that involved only two numbered highways.
