Indigenous cables, the Peace Bridge is supported by

Indigenous Peoples, including the Piikani,
Kainai and Siksika of the Blackfoot Confederacy as well as the Tsuut’ina and Nakoda, have inhabited the Bow River Basin for more than 10,000 years.
Fluctuations in river flow often dictated where and how Indigenous Peoples
would travel in the plains. Permanent occupation of the floodplain began with
the establishment of Fort Calgary and a Hudson’s Company trading post in 1875.
Several years later in 1883, the arrival of the Canadian Pacific Railway marked
the beginning of The City of Calgary.

Connecting communities across the Bow and Elbow
Rivers has always been a priority for the City. The first bridges were
constructed in the late 1800’1 s and there are currently over 50
vehicle and pedestrian bridges spanning the rivers. In 2008, c2 ouncil approved the construction of
a new pedestrian and cyclist bridge over the Bow River to better connect
northern communities to downtown.

The location for what would become the Peace
Bridge presented some very site-specific challenges for the designers, Santiago
Calatrava Architects and Engineers. To avoid impacting fish habitat, permanent
foundations were not permitted in the river; the proximity of the adjacent
helipad necessitated a six-metre height restriction, and3 ;
and4  the bridge needed to be above the 1:100 flood event.5 

Calatrava called the bridge “the most
accessible, functional and technically challenging” bridge he’s ever designed. The steel structure
is a sculptural, mathematically-derived form that presents a striking contrast
with the surrounding landscape. With no beams, arches or cables, the Peace
Bridge is supported by foundations on either side of the river. The shape is
defined by a helix over an oval cross section with two clearly defined
tangential radii creating the space within. The upper openings are closed with
glass ‘leaves’ to offer protection from the elements. It is 126 metres long and 8 metres wide with
an interior width of 6.2 metres and height of 5.85 metres. 6 

Construction took over 27  years to complete. The steel was
shipped from Spain in 15-metre sections and welded on the banks of the Bow. Once complete,
hydraulic rams nudged the truss across the river on a temporary bridge and was
then lifted into place on the concrete abutments. 8 

The Peace Bridge represents Calgary’s commitment
to accessible, active-transportation infrastructure. With a designated cycling
centre lane flanked by pedestrian paths on either side, the Peace Bridge is
traversed over 6000 9 times daily, exceeding original
projections. It10  has become a landmark for the City
and a destination for both locals and visitors.
