It is a steel girder bridge, built in 1983 as part of the Circle Drive freeway system in northeast Saskatoon.

However, rather than widening the bridge by filling in the centre gap, it was deemed to be more cost effective to convert the outside pedestrian walkways into driving lanes.

In 2006, construction started on adding a third outside lane in both directions to increase capacity and ease congestion during peak traffic times.

Her car went over built-up snow along the guard rail, which launched the vehicle up and over the side of the bridge.

Pegg escaped the vehicle by kicking out the windshield, standing on top of the car and swimming to a nearby sheet of ice.
