Crowchild Trail is a major expressway in western Calgary, Alberta. The segment from the 12 Mile Coulee Road at the edge of the city to 16 Avenue NW (Trans-Canada Highway, Highway 1) is designated as Highway 1A by Alberta Transportation (although inside the City of Calgary the 1A designation is not signed except at the Alberta Transportation built interchange with Stoney Trail). The road is a critical north-south link in West Calgary for both downtown bound traffic and travel between the two quadrants of the city it passes through. Although planned to be one single freeway from Glenmore Trail to the city limits, the route is currently divided by a section of slow moving arterial road with four signalized intersections between 24 Avenue and Memorial Drive. This causes the freeway in the northwest to separated from the freeway south of the Bow River. Filling the gap and making the whole route a minimum six lane freeway is currently planned for construction beyond 2027. Route description Crowchild Trail's south terminus is located at North Glenmore Park as a minor park access road. It soon exits the park and becomes a minor arterial road where it intersects several residential streets within the communities of Lakeview and North Glenmore Park, several residential dwellings are located on the Trail itself. Continuing northward, its first major intersection is with Glenmore Trail at an interchange that was built in 1981. Traffic flows freely from Westbound Glenmore on to Crowchild north and vice versa through a 2-lane flyover but all other movements on Crowchild pass through signal lights. North of this interchange Crowchild becomes a freeway, following Glenmore there are interchanges at 50th Avenue SW, Flanders Avenue SW, 33 Avenue SW and 17 Avenue SW. From there it enters a system interchange with 10 Avenue SW and Bow Trail before crossing the Bow River on an eight-lane bridge. The south section of freeway from Glenmore to Bow Trail has eight through lanes, however the outermost set are HOV lanes for public transit only, leaving six lanes for drivers. After crossing the Bow River it passes through an incomplete systems interchange at Memorial Drive before the freeway ends. The speed limit on the freeway sections of Crowchild are to . Traffic slows immediately north of the Memorial Drive (dropping to a seven lane wide principal arterial with a limit), passing signal-controlled intersections at Kensington Road NW and 5
