Deerfoot Trail is a 46.4-kilometre (28.8 mi) freeway segment of Highway 2 in Calgary, Alberta, Canada. It stretches the entire length of the city from south to north and links suburbs to downtown via Memorial Drive and 17 Avenue SE. It also forms part of the CANAMEX Corridor which connects Calgary to Edmonton and Interstate 15 in the United States via Highways 3 and 4. The freeway begins south of Calgary where it splits from Macleod Trail, crosses the Bow River into city limits, and reaches the Stoney Trail ring road. Crisscrossing twice more with the river, it intersects Glenmore Trail and Memorial Drive; the former is a major east–west expressway while the latter is a freeway spur into downtown. In north Calgary, it crosses Highway 1 and passes Calgary International Airport before ending
