Design and construction of a 476 meter long by 20 meter wide bridge crossing the Bow River as part of the Stoney Trail N.W. dual carriage-way bypass being built by the City of Calgary. The bridge is being constructed employing the Incrementally Launched Method for precast concrete bridges. Each section is 25 meters long by 4.5 meters deep, except the ends which are 22 meters long. The bridge is a double cell box structure and will be matched case in two stages, i.e. soffit and webs followed by the deck in two adjacent casting yards. Four permanent and five temporary piers vary in height from 22 up to 33 meters. The work includes a 130 meter long by 3 meter wide pedestrian suspension bridge which is under-hung from the substructures at Piers 2 and 3.
