Built in 1976, the Hog’s Back Bridge is an unequal arm swing bridge spanning the Rideau Canal. The swing features operate from mid-May to mid-October, with the bridge opening up to 20 times per day during the peak of the navigation season. Hog’s Back Road is an integral pedestrian, bicycle and vehicle linkage across the Rideau Canal (carrying 18,000 to 26,000 vehicles per day).
