Provincial highways in Alberta

Alberta Provincial Highway No. 4, commonly referred to as Highway 4, is a 103-kilometre (64 mi) highway in southern Alberta, Canada that connects Highway 3 in Lethbridge to Interstate 15 in Montana, and is the southernmost portion of Alberta's Export Highway. It begins at Alberta's busiest border crossing in Coutts, winding north through gentle rolling hills and farmlands in the south of the province. It bypasses Milk River, Warner and Stirling before reaching Lethbridge where it becomes 43 Street and ends at Crowsnest Trail on the east side of the city. In 1995, it was designated as part of the CANAMEX Corridor that links Canada to Mexico and the United States, including the major cities of Salt Lake City, Las Vegas, Los Angeles, and San Diego which lie on Interstate 15. In 1999, the highway was renamed the First Special Service Force Memorial Highway in honour of elite soldiers who travelled to Helena, Montana for training in preparation for World War II. Between Lethbridge and Highway 61 near Stirling, Highway 4 is signed as part of the Red Coat Trail, a historic route stretching from southern Alberta into Manitoba that is advertised as that which was travelled by the North-West Mounted Police.
