16 Avenue N is a major road in Calgary, Alberta, that forms a 26.5-kilometre (16.5 mi) segment of Highway 1 and connects Calgary to Banff and Medicine Hat. It is a four to six-lane principal arterial expressway at its extremities, but is an urban arterial road between the Bow River and Bowness Road, and also between Crowchild Trail and Deerfoot Trail. Due to Calgary's quadrant system, it is known as 16 Avenue NW west of Centre Street and 16 Avenue NE to the east.

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 is designated as Highway 1A by Alberta Transportation. 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.
