In 1988, the City of Winnipeg, Manitoba, Canada, used architectural precast concrete to build three multispan pedestrian bridges spanning a retention pond in Kil-Cona Park. The 12 arch panels required for the three bridges were cast from one form. The three bridges' superstructures use 39 precast concrete components: arch span panels, end span panels, and diaphragms. The foundations use 42 precast concrete piles. Precast erection of the three bridges took just 3 days.
The color, size, and shape of the exposed precast concrete arches blend in well with the stone veneer. The precast panels were cut so that the exposed portions of the handrail could be given a steel trowel finish resulting in a hard, durable surface, free of defects. The polyethylene sheet curing technique used by the precaster resulted in a mottled finish that complements the natural finish of the cut stone handrail trim. Workers installed irregular crack control joints in the stone veneer at precast component joints to accommodate differential movement. The joints are almost invisible because a continuous foam joint fill was used and the caulking matched the mortar color.
