Kicking Horse Cantilever Structure

The largest cantilever roadway structure in B.C was completed in 2007 on the Trans-Canada Highway approximately 10 km east of Golden in the Kicking Horse Canyon. In September 2004, Emil Anderson Construction Inc. was awarded the $17 million contract to upgrade a section of Highway #1. The tender design included the construction of a pair of bridges crossing and returning over Kicking Horse River in order to facilitate the widening of a 2.1 km stretch of highway from two to four lanes. Klohn Crippen Berger was engaged by the contractor to develop a Value Engineering redesign for the project. The objective was to develop a more economical and constructible design within the extremely rugged and environmentally sensitive terrain of the Kicking Horse Canyon. The use of structural and geotechnical design innovations, along with highway alignment optimization, allowed the roadway to remain wholly on the south side of the river. A unique and simple design concept was used to cantilever a 155m long section of roadway off the south bank of the river. By eliminating the need for the two new bridges, savings of $2.5 million were realized, as well as dramatic reductions in the environmental impact of the project.
