Statement of Significance

Description of Historic Place

The High Level Bridge is a massive steel truss multi-function bridge with a total of 28 spans, set on a combination of concrete piers and steel legs. The High Level Bridge is 777.24 metres long and the base of the rail deck is 47.55 metres above the North Saskatchewan River mean water level. It links 109 Street on Edmonton's south side with 109 Street in Edmonton's downtown.

Heritage Value

The High Level Bridge is significant as one of the four great steel truss bridges constructed by the Canadian Pacific Railway (CPR) in Canada before World War One. The High Level Bridge was constructed between 1910 and 1913, and its design employs two distinct truss types, the Pratt Truss and the Warren Truss, for the steel substructure. The steel superstructure features two decks, one twenty feet above the other. The High Level Bridge, despite alterations and ongoing maintenance, retains its historical character and integrity of design and fabric.

The High Level Bridge has unique significance in western Canada for its original combination of four modes of transportation: train, streetcar, automobile and pedestrian. Streetcar traffic ceased in 1951, and the CPR stopped running trains over the upper deck in 1989. Vehicular traffic and a pedestrian walkway continue on the lower deck, while a tourist streetcar runs seasonally on the upper deck.

The High Level Bridge is also significant as a landmark and as an icon for the city of Edmonton.
