Abstract: Constructing a curved steel bridge high above a canyon floor presents a unique set of conundrums, including how to elevate the girders high enough without inducing warping and how to protect them from strong and unpredictable wind gusts. In British Columbia, a public-private partnership of design and construction professionals resolved these issues for a bridge above Kicking Horse Canyon by choosing a girder launching system that had not previously been attempted on a bridge of that magnitude anywhere in North America.
