Calgary Trail/Ellerslie Road Interchange

The Calgary Trail and Ellerslie Road interchange is situated on the south side of Edmonton, Alberta. This $10.5 million interchange project involved the construction of two large bridge structures and more than 6 kilometres of roadway.

Crews used an innovative phased construction method to construct the first bridge, which measured 127 metres long by 27 metres wide. The bridge was cast-in-place at grade, post-tensioned and then excavated to expose the completed structure. A second bridge, measuring 38 metres long by 15 metres wide, was constructed using a single-span precast method.

The east and west retaining walls were more than 700 metres long and supported by drilled cast-in-place concrete piles. Crews constructed more than 6 kilometres of roadway including 65,000 cubic metres of excavation, 112,000 cubic metres of native fill, 66,000 tonnes of road base and 23,000 tonnes of asphalt.

Thorough planning by project personnel minimized impacts to the traveling public and allowed for completion of the project in June 2001.
