The City of Airdrie stated on its website, that along with the construction of the structure itself, other construction work including realigning Nose Creek, moving, importing, placing, and compacting over 500,000 cubic metres of clean fill, as well as installing four sets of traffic signals would also be undertaken.

"The interchange at Highway 2 and 40th Avenue was identified by the Province as a necessary project in the early 2000’s. In 2019, the project was ranked [number] 2 in a study of critical North Calgary Regional Transportation projects. Significant growth pressure and traffic congestion on local roadways led the City of Airdrie to move forward on this project in 2021," the City added.

The project cost $65 million, with the province contributing $11.5 million, while The City of Airdrie was responsible for the remainder of the cost.
