Alberta Provincial Highway No. 4 is a north-south highway in southern Alberta, Canada. It is designated a core route in Canada's National Highway System, connecting Lethbridge to the United States, and comprises the southernmost leg of the CANAMEX Corridor. Highway 4 spans approximately 103 km (64 mi) from Alberta's border with Montana to the Crowsnest Highway (Highway 3). It is preceded by Interstate 15, which connects Alberta with American cities such as Salt Lake City, Las Vegas, Los Angeles, and San Diego.
Between Lethbridge and Stirling, Highway 4 is designated part of the Red Coat Trail, which continues as Highway 61 east towards the Saskatchewan border and continues as Highway 3 west to Highway 2 near Fort Macleod.
Interstate 15 becomes Highway 4 as it crosses the international border between Montana and Alberta. The route is a four-lane divided highway for its entire length from the Village of Coutts, which is located at the border, to Highway 3 in the City of Lethbridge. Outside urban areas, the speed limit of Highway 4 is 110 km/h (70 mph).
Generally travelling in a northwest direction from Coutts, the highway bypasses the Town of Milk River and the Village of Warner, passes by the Hamlet of New Dayton, and provides access to the Village of Stirling via Highway 846. The highway enters Lethbridge as 24 Avenue S, and then turns north onto 43 Street S to Highway 3.
Within Lethbridge, Highway 4 once continued along 24 Avenue S, beyond 43 Street S, to Highway 5 (Mayor Magrath Drive), and then continued in a northwest direction along Scenic Drive S to Highway 3.
In September 1999, Highway 4 and Interstate 15 in Montana — being the main highway between the cities of Helena and Lethbridge — was designated the First Special Service Force Memorial Highway. It was named after this force as this was the route travelled in 1942 by its Canadian volunteers to join its American counterparts for training at Fort William Henry Harrison.
