Circling Edmonton

Earth Tech Canada Left: the North Saskatchewan River Bridge on the southwest leg of the Anthony Henday Road is the first major new river crossing to be built in Edmonton in 30 years. Designed by Earth Tech, with Stantec, EBA and several other subconsultants, the bridge is a parallel twin structure, 360-metres long. It is designed for two future stages of widening and has a suspended pedestrian walkway beneath the southbound bridge. Unstable headslopes and soft foundation conditions called for special detailing. The north abutment fills, for example, are expected to shift 200 mm, either laterally or to the river. To accommodate this, the abutments were designed to move with the fills, while allowing the girders to be adjusted with time as the movements progress.
