Within Taber, Highway 36 runs concurrently with Highway 3 for 3 km (2 mi). The highway meets the northern end of Highway 4 at the eastern limit of Lethbridge before continuing east to Coaldale and Taber. Highway 3 again crosses the Oldman River in central Lethbridge and the freeway segment ends at Mayor Magrath Drive, marking the northern terminus of Highway 5. It then becomes a freeway named Crowsnest Trail as it reaches Highway 25 which branches north to Picture Butte while University Drive runs south to the University of Lethbridge as the main thoroughfare through West Lethbridge. Īfter Coalhurst, the highway reaches Westview Drive W, which provides access to West Lethbridge. Highway 3 then crosses the Oldman River east of Fort Macleod near Monarch, prior to a partial interchange with Highway 23.

It proceeds for 5 km (3 mi) into the town of Fort Macleod, after which Highway 2 splits south to Cardston and the United States border. Approximately 50 km (31 mi) east of Pincher Creek, the highway becomes divided and interchanges with Highway 2 with which it is briefly concurrent, assuming the designation of the Red Coat Trail and CANAMEX Corridor. Highway 6 splits south near Pincher Creek. It begins in Crowsnest Pass paralleling the Canadian Pacific Railway, first meeting Highway 40 at Coleman, then running 26 km (16 mi) east to the southern terminus of Highway 22. The Alberta portion of the Crowsnest Highway is also designated as Highway 3, running for approximately 323 km (201 mi) from the British Columbia border to Medicine Hat. 31 km (19 mi) northeast of Elko, the Crowsnest Highway reaches Fernie, then it goes north another 30 km (19 mi) to its junction with Highway 43 at Sparwood, and another 19 km (12 mi) east, the highway reaches the boundary with Alberta at Crowsnest Pass. Highway 93 and the Crowsnest share a common alignment for the next 53 km (33 mi) southeast to Elko, where Highway 93 diverges south. Another 6 km (4 mi) east, Highway 95 diverges north while Highway 93 merges onto the Crowsnest Highway from a shared alignment. The two highways share a common alignment for 72 km (45 mi) northeast to Cranbrook and the junction with Highway 95A. 40 km (25 mi) later, south of Yahk, Highway 95 merges onto the Crowsnest Highway. 67 km (42 mi) east of Burnt Flat, the Crowsnest Highway reaches Creston, just past junctions with Highway 21 and Highway 3A. The Crowsnest Highway continues through the Kootenay Pass on the Salmo-Creston Highway, a stretch known colloquially as the Kootenay Skyway, or Salmo-Creston Skyway. Approximately 26 km (16 mi) east of Castlegar, the Crowsnest Highway reaches its eastern junction with Highway 3B another 11 km (6.8 mi) to the east it converges with Highway 6 at Salmo and the two highways share a concurrency for 14 km (9 mi) to Burnt Flat. It is another 26 km (16 mi) east to Castlegar, where the Crowsnest Highway intersects Highway 22 and Highway 3A, leading towards Nelson. The Crowsnest Highway travels for 47 km (29 mi) through Bonanza Pass to its junction with Highway 3B at Nancy Greene Lake, which is the cutoff to Rossland and Trail. Another 26 km (16 mi) east, the Crowsnest Highway meets Highway 395 at the southern end of Christina Lake. The highway forms part of the Red Coat Trail and the CANAMEX Corridor from Highway 2 near Fort Macleod to Highway 4 in Lethbridge.Īpproximately 52 km (32 mi) east of Osoyoos, the Crowsnest Highway reaches its junction with Highway 33 at Rock Creek, then the highway heads east for 70 km (43 mi) to its junction with Highway 41, just before passing through Grand Forks. In Alberta, the terrain is initially mountainous, before smoothing to foothills and eventually generally flat prairie in the vicinity of Pincher Creek.

The first segment between the Trans-Canada Highway and Highway 5A is locally known as the Hope- Princeton Highway, and passes by the site of the Hope Slide.

In British Columbia, the highway is entirely in mountainous regions and is also known as the Southern Trans-Provincial Highway. It takes its name from the Crowsnest Pass, the location at which the highway crosses the Continental Divide between British Columbia and Alberta. Mostly two-lane, the highway was officially designated in 1932, mainly following a mid-19th-century gold rush trail originally traced out by an engineer named Edgar Dewdney. It stretches 1,161 km (721 mi) across the southern portions of both provinces, from Hope, British Columbia to Medicine Hat, Alberta, providing the shortest highway connection between the Lower Mainland and southeast Alberta through the Canadian Rockies. The Crowsnest Highway is an east-west highway in British Columbia and Alberta, Canada.
