The Nose Hill Interchange is a key transportation project that improves connectivity between Highway 1 (Trans-Canada Highway), Highway 2 (Deerfoot Trail), Stoney Trail (Highway 201), and Nose Hill Drive in Calgary, Alberta. By modernizing one of the city's busiest highway junctions, the project enhances traffic flow, improves safety, and supports the efficient movement of people and goods throughout the region.

ACCIONA served as the main contractor, responsible for the overall management and delivery of the project. While Alberta Transportation provided the primary design, ACCIONA also completed the detailed design of critical structural components, including bridge bearings, expansion joints, mechanically stabilized earth (MSE) walls, and steel diaphragms, working closely with specialist suppliers and engineering partners.

The 4.5-kilometre project involved the construction of three new bridges, including two road bridges and a pedestrian bridge, as well as the widening of an existing bridge over the Canadian Pacific Railway. Additional works included two new underpasses and the extension of two existing underpasses, requiring careful coordination to maintain traffic and minimize disruption during construction.

The completed Nose Hill Interchange delivers lasting transportation benefits by improving safety, reducing congestion, and increasing capacity at one of Calgary's busiest highway junctions. Enhanced traffic operations, more reliable connections between the city's major transportation corridors, and carefully planned construction sequencing have improved mobility for commuters, commercial traffic, and active transportation users while supporting Calgary's continued growth and strengthening one of the region's most important transportation gateways.
