Canada. The speed limit along most parts of the highway between Fort Macleod and Morinville is and in urban areas, such as through Claresholm, Nanton, Calgary and Edmonton, it ranges from to . During the winter, accidents are common on the stretch of the highway between Calgary and Edmonton as the weather can change rapidly and drivers underestimate the conditions, overwhelming emergency services attempting to respond. As the main north–south access in Alberta, Highway 2 is the preferred path of the CANAMEX Corridor. Between Fort Macleod and Edmonton, Highway 2 maintains no fewer than four lanes of traffic and is largely a freeway between Okotoks and Edmonton, with improvements underway to eliminate the at-grade crossings that remain. Southern Alberta Foothills Highway 2 begins at the United States border, as the two lane U.S. Route 89 crosses into Canada at Carway. The road proceeds north through the Rocky Mountain Foothills to a brief concurrency with Highway 501, before bisecting the town of Cardston. At the north end of town, the highway enters Blood Indian Reserve No. 148 and Highway 5 splits west to Waterton Lakes National Park; it is briefly concurrent with Highway 2 before splitting east to cross the St. Mary River en route to Magrath and Lethbridge. Highway 2 continues north to another short concurrency with Highway 505 during which it crosses the Waterton River to Stand Off, continuing across the Belly River to Fort Macleod in the Municipal District of Willow Creek. Less than 1 km before meeting Highway 3 southeast of Fort Macleod, Highway 2 becomes a divided highway. Highway 3 splits east to Lethbridge, and the combined Highways 2 and 3 turn due west through town as a divided highway at a speed limit of 50 km/h. West of town, the highways diverge at an interchange; Highway 3 continues west as the Crowsnest Highway to Pincher Creek and British Columbia, and Highway 2 turns north across the Oldman River as a divided highway. It continues approximately north to Granum from which Highway 519 splits to the east. In tandem with Highway 23, Highway 519 is often used by CANAMEX traffic to bypass Fort Macleod. Further north on Highway 2, the towns of Claresholm and Nanton are each bisected at a reduced speed limit of 50 km/h. The highway is concurrent with Highway 533 for its brief distance through Nanton. North of Nanton, the highway continues into
