Fort Edmonton Footbridge and Icefields Interchange


While the rebuilding of Edmonton's Quesnell Bridge seemed to grab all the attention, another bridge project over the North Saskatchewan River not far away is equally impressive.

It's the $23.5-million Fort Edmonton Footbridge. Designed by HFKS Architects Inc. and built by Alberco Construction Ltd. of St. Albert, it's one of the few suspension bridges in Alberta. The bridge's centre span is 138 m with abutment spans of 54 m for a total of 246 m. The two piers that hold the 110 mm main suspension cables rise 32 m above the river, and the abutments each contain 60 soil anchors for the suspension cables.

The superstructure deck? It has 72 precast deck segments, which are suspended with vertical cables from the main cables. The superstructure precast is grouted and post tensioned and incorporates a wind-dampening system at each abutment.

CH2M Hill was the engineer. Cohos Evamy also played a key role in the project.


The upgrade of the Icefields Interchange at the junction of Highway 93 and the Trans-Canada near Lake Louise, Alta., involved demolition, design and construction on a busy highway, yet it was completed in just 14 months.

Graham Design Builders was general contractor for the design-build project. It was designed by EBA Engineering Consultants Ltd.

The $22-million project included demolishing the overpass, removing 250,000 tonnes of rock, placing 132,500 tonnes of granular materials and 35,000 tonnes of asphalt pavement, and constructing a new overpass and ramps. The Trans-Canada Highway was widened and twinned, and a bridge was built over the Bow River.

Street lighting, signage, culvert installation, landscaping, fencing and traffic accommodation were also all accomplished while traffic continued to flow.

CH2M Hill provided structural engineering while Fortis Alberta provided electrical engineering. Thurber Engineering Ltd. was responsible for pavement design.
