Provincial highways in Alberta
The Crowsnest Highway is an east-west highway in British Columbia and Alberta, Canada. It stretches 1,161 km (721 mi) across the southern portions of both provinces, from Hope, British Columbia to Medicine Hat, Alberta, providing the shortest highway connection between the Lower Mainland and southeast Alberta through the Canadian Rockies. The mostly two-lane highway was officially designated in 1932, mainly following a mid-19th century gold rush trail originally traced out by an engineer named Edgar Dewdney. It takes its name from the Crowsnest Pass, the location at which the highway crosses the Continental Divide between British Columbia and Alberta.
In British Columbia, the highway is entirely in mountainous regions and is also known as the Southern Trans-Provincial Highway. The first segment between the Trans-Canada Highway and Highway 5A is locally known as the Hope-Princeton Highway, and passes by the site of the Hope Slide. In Alberta, terrain is initially mountainous, before smoothing to foothills and eventually generally flat prairie in the vicinity of Pincher Creek. The highway forms part of the Red Coat Trail and the CANAMEX Corridor from Highway 2 near Fort Macleod to Highway 4 in Lethbridge.
