Crowsnest Highway

The peak of Allison Pass.

The Crowsnest Highway's western terminus is at Hope, where it branches off from the Trans-Canada Highway (Highway 1). The highway goes east for 7 km (4 mi) to its junction with the Coquihalla Highway (Highway 5), where it exits the freeway and continues for 127 km (79 mi) on a segment known as the Hope-Princeton Highway, passing the Hope Slide en route to Allison Pass, Manning Provincial Park, and Sunday Summit; at Princeton, the Crowsnest Highway meets Highway 5A.[2] East of Princeton, the Crowsnest Highway goes southeast for 67 km (42 mi) to Keremeos, where it meets Highway 3A, leading towards Penticton and Highway 97. Another 46 km (29 mi) southeast, and the Crowsnest Highway reaches Osoyoos and a junction with Highway 97.

Approximately 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. Another 26 km (16 mi) east, the Crowsnest Highway meets Highway 395 at the southern end of Christina Lake.[2] 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. It is another 26 km (16 mi) east to Castlegar, where the Crowsnest Highway intersects Highway 22 and Highway 3A, leading towards Nelson. 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.[2]

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. 67 km (42 mi) east of Burnt Flat, the Crowsnest Highway reaches Creston, just past junctions with Highway 21 and Highway 3A. 40 km (25 mi) later, south of Yahk, Highway 95 merges onto the Crowsnest Highway. The two highways share a common alignment for 72 km (45 mi) northeast to Cranbrook and the junction with Highway 95A. Another 6 km (4 mi) east, Highway 95 diverges north while Highway 93 merges onto the Crowsnest Highway from a shared alignment. Highway 93 and the Crowsnest share a common alignment for the next 53 km (33 mi) southeast to Elko, where Highway 93 diverges south. 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.[2]

Highway 3 near Cowley, Alberta

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. 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. Highway 6 splits south near Pincher Creek. 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. 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. Highway 3 then crosses the Oldman River east of Fort Macleod near Monarch, prior to a partial interchange with Highway 23.[3]

After Coalhurst, the highway reaches Westview Drive W, which provides access to West Lethbridge. 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. 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. The highway meets the northern end of Highway  4 at the eastern limit of Lethbridge before continuing east to Coaldale and Taber.[3] Within Taber, Highway 36 runs concurrently with Highway 3 for 3 km (2 mi). The highway reduces to a two-lane undivided road and the Crowsnest Highway ends 113 km (70 mi) later at the Trans-Canada Highway in Medicine Hat.
