Peace Bridge is a pedestrian bridge, designed by Spanish architect Santiago Calatrava, that accommodates both pedestrians and cyclists crossing the Bow River in Calgary, Alberta, Canada. The bridge opened for use on March 24, 2012.
Contents
The bridge was built by The City of Calgary to connect the southern Bow River pathway and Downtown Calgary with the northern Bow River pathway and the community of Sunnyside. This connection was designed to accommodate the increasing number of people commuting to and from work and those utilizing Calgary's pathways. The bridge is reportedly used by 6000 people a day and has ranked among the top 10 architectural projects in 2012 and among the top 10 public spaces of 2012.
Design
The design follows strict requirements with no piers in the water (in an effort to minimize the ecological footprint) and restricted height (due to the vicinity of the City/Bow River Heliport).
The bridge has also been designed to:
The bridge is a departure from Calatrava's previous designs, which were typically asymmetric shapes anchored by high masts. Another atypical element is the color; while most of Calatrava's designs are white, the Peace Bridge features red and white as used in both the Flag of Canada and the Flag of Calgary.
Cost
Funding for the Peace Bridge was provided by the city's capital budget. For the transportation department, targeted expenditures of capital are directed by the Transportation Infrastructure Investment Program (TIIP), which defines the priority and timing of major infrastructure construction projects. This program emphasizes pedestrian and cycling in high-density areas where these modes are more efficient at moving people, supporting land use and lessening environmental impacts. As of February 2012, the approximate costs were:
History
On September 8, 2008, Calgary City Council approved report LPT2008-49 which set aside $25 million for the Pedestrian Gateways project for two bridges across the Bow River: one west of Prince's Island Park and one at the west of St. George's Island. The decision directed Administration to design and build one bridge and develop a concept design for a second one.
Construction started in March 2010. A temporary structure was built immediately upstream from the bridge location and served as a place to assemble the bridge before moving it to its final position.
The tubular bridge was manufactured in Spain and shipped to Calgary. Assembly of the bridge pieces started in Fall 2010 and the bridge was moved across the Bow River in November 2011.
During routine weld inspection, it was discovered that some of the welds did not comply with quality standards. As a result, the city hired an independent inspection company to do a more thorough inspection of the welds completed in Spain. The added inspections, red flags about the steel work's esthetics, weld repairs, and issues with damaged concrete slabs all contributed to multiple delays in the opening of the bridge.
The bridge, originally supposed to be opened in the fall of 2010, opened to the public on March 24, 2012.
Criticism
$700,000 for replacement lights. Originals couldn't hold up to Calgary winters. Welding was sub-par and had to be redone. Replacement glass was approximately $130,000.
The Peace Bridge has drawn much criticism from the public, namely:
The bridge bears some similarity to the Hans Wilsdorf Bridge in Geneva, designed by the architectural firm of Brodbek-Roulet.
