Alberta Provincial Highway No. 22, commonly referred to as Highway 22 and officially named Cowboy Trail, is a highway in the Canadian province of Alberta. It generally parallels Highway 2, beginning in the foothills of southern Alberta at Highway 3 near Lundbreck Falls. It proceeds north along the eastern slopes of the Rocky Mountains passing through the foothills and ranch country to the aspen parkland of northern Alberta, ending at Highway 18 near Mayerthorpe. Cowboy Trail continues south and east of Highway 22 by following Highway 3 to Pincher Creek, Highway 6 to Waterton Lakes National Park, and Highway 5 to Cardston. Alberta Transportation is currently constructing a new interchange at the over-saturated intersection of Highways 22 and 1A in Cochrane. There are also long-term plans for twinning from Bragg Creek to the north end of Cochrane, and the implementation of passing lanes near the highway's south end. Route description Highway 22 begins as a two-lane rural highway in the Municipal District of Pincher Creek No. 9 near Lundbreck Falls at Highway 3, the Crowsnest Highway. It proceeds north across increasingly flatter terrain of the foothills, parallel to the Oldman River, and then crosses it before entering the Municipal District of Ranchland No. 66. The highway winds to the east of the Black Heritage Rangeland Natural Area, intersecting Highway 520 which branches east to meet Highway 2 at Claresholm. Highway 22 continues north through scenic terrain to the Chain Lakes Reservoir, from which Highway 533 splits east to meet Highway 2 at Nanton. The highway continues north through Longview, Diamond Valley (made up of the former twin towns of Black Diamond and Turner Valley), and Millarville. The highway then jogs west at Highway 22X. Approximately later, the road turns north again and passes through Bragg Creek where Highway 22X ends. Highway 22 continues north past the Trans-Canada Highway (Highway 1) west of Calgary, north through the Town of Cochrane, the Hamlet of Cochrane Lake, and the Village of Cremona to Highway 27. The highway continues in a generally northward direction (with a number of westward jogs), passing through Sundre, Caroline, Rocky Mountain House and Drayton Valley until it intersects Highway 16 (Yellowhead Highway) at Entwistle approximately west of Edmonton). After a jog to the west, it continues north to cross Highway 43 in Mayerthorpe, ending north of the town at Highway 18. History The original alignment of Highway 22 started
