the Foothills County to a major junction with Highways 23 and 2A at High River, after which it veers northwest to cross the Highwood River. On the other side of the river, a second interchange provides access to Okotoks via Highways 7 and 2A, and Highway 2 continues north across the Sheep River to De Winton where Highway 2A splits into southwest Calgary as Macleod Trail, and Highway 2 veers northeast toward the Bow River valley and southeast Calgary. Calgary From its split with Macleod Trail, Highway 2 becomes a major freeway named Deerfoot Trail that descends to cross the Bow River before entering Calgary city limits. In the city it crosses the river twice more, jogging back and forth between its east and west bank. The freeway intersects the Stoney Trail ring road at the south end of Calgary, with signage recommending that traffic en route to Calgary International Airport, Edmonton, and Medicine Hat use eastbound Stoney Trail as a bypass.
