Mount Hunter Creek Bridge spans a steep ravine along the Trans-Canada Highway approximately 20 kilometers east of Golden, BC, in the Rocky Mountains.

This bridge consists of six steel plate girders with a composite concrete deck. Each girder is 3.5m deep and spans 80m. Once completed, this four lane crossing will replace the existing truss bridge increasing the capacity for this critical transportation route.

Girders were braced in pairs, lifted onto dollies, and then floated over the existing bridge into the lifting position with a semi-tractor. A temporary work platform and outrigger supports were designed for a DEMAG CC1500 and Liebherr LTM 1250 crane respectively. The girders were lifted, swung into position, and lowered onto sliders at the north end of the new abutments. A slider beam and pulley enabled a transverse launch of the girders to their bearing locations. These 220 ton lifts required the full capacity of both cranes.
