transferred to the Town of Canmore. The roadway still carries the name "Bow Valley Trail". From exit 91, it heads eastbound, along the Canadian Pacific Railway tracks, until it reaches the Hamlet of Exshaw. From Exshaw, Bow Valley Trail heads to the northeast, past Highway 1X. Just east of Highway 1X, Bow Valley Trail narrows and the speed limit is reduced to for approximately thirty kilometres as it passes through the Stoney-Nakoda First Nation, where warning signs that there may be livestock and/or pedestrians on the road are posted. Highway 1A passes Morley approximately eight kilometres from the eastern boundary of the area; the community is situated just south of the highway. As the Highway leaves the area, it widens and the speed limit increases back to . Shortly after resuming its normal speed limit, the highway skirts the north shore of Ghost Lake, a manmade glacier lake that is a popular spot for Calgary's boating and sailing enthusiasts in the summer, as well as ice sailing in the winter. The lake also supplies most of the water power for Calgary through TransAlta Utilities. Highway 1A meets northbound Highway 40 approximately after passing Ghost Lake. From Highway 40, Bow Valley Trail proceeds towards the east, and then slightly to the southeast, before reaching the Town of Cochrane, where it intersects with Highway 22. There, the highway widens to 4 lanes as it leaves Cochrane and proceeds southeast until it reaches Calgary, meeting northbound Highway 766 about west of the city limits. Upon reaching the Calgary city limits at 12 Mile Coulee Road, it continues as Crowchild Trail, a major north-south expressway, (although it travels in a southeasterly direction from the city limits to 24 Avenue NW) through the northwest and southwest parts of the city. Within Calgary, it crosses Stoney Trail (Highway 201) as well as a number of major streets, before reuniting with the Trans-Canada Highway (known as 16 Avenue N) near McMahon Stadium and the University of Calgary. The section along Crowchild Trail is maintained by the City of Calgary rather than Alberta Transportation. Before 1972, this route was the only road to Banff National Park.
