Abstract
Two distinct bridge superstructures were recently launched in Western Canada using a system specifically designed to accomplish challenging launch projects. The Park Bridge is a steel plate girder superstructure on Trans-Canada Highway #1 in the mountains of the Kicking Horse Canyon, British Columbia. The Coast Meridian Overpass is a steel box girder and cable-stay structure in the City of Port Coquitlam, British Columbia. Although very different in appearance and design, these bridges have three similarities: they are both composed of steel, both are the result of fast track design-build process, and both were erected by a specialised system that employs the incremental launch method. This paper provides an overview of the launching of these two steel superstructures.
