Calgary is blessed with almost 1,000 km of pathways (one of the world’s largest urban pathways) used by pedestrians, runners and cyclists year-round. One of the key elements of the pathways system is its pedestrian bridges which range from “plain jane” functional bridges to multi-million dollar iconic bridges designed by world renowned architects and engineers. Some have been created with much controversy, while others have flown under the radar.
This is the story of three recently completed pedestrian bridges that I have been following for several years – Bow Trail, Peace and St. Patrick’s Island bridges.
Calgary’s “Other Red Bridge”
While the Peace Bridge and St. Patrick’s Island bridges got all the media attention, the new pedestrian bridge over Bow Trail at the western entrance into the downtown just quietly got built. As a minor element in the massive billion-dollar West LRT project, there was no international design completion, nor any elaborate public engagement process. The design was given to two local engineers - Edmund Ho and Monty Knaus of Calgary’s MMM GROUP.
In their 2014 Transportation Association of Canada (Structures Session) Conference presentation, the bridge is described as a “rotated-ellipse arch,” but most people just see it as a representation or interpretation of Calgary’s iconic Chinook Arch. In my mind, there couldn’t be a more appropriate design for one of the downtown’s key gateways, seen by 100,000+ Calgarians and visitors who pass under it, cross over it or by it (Crowchild Trail) every day.
Its Canada Flag red colour helps make it stand out against the dramatic Calgary sky that can range anywhere from pure white to deep blue. Usually I am the guy asking for more ornamentation, but in this case, the simplicity of the design works well. Who says engineers have no sense of urban design? It also offers one of the best views of Calgary’s stunning downtown vista, which becomes visible at exactly this point when travelling east.
This bridge is an important connection in Calgary’s pathway system as it provides a connection to the Bow River pathway for all of the communities west of Crowchild Trail and south of Bow Trail, for both leisure and commuter use. It also provides access to a bus stop on Bow Trail.
The bridge spans all six lanes of traffic as well as the LRT track, with a span length of 50 metres from end-to-end of the half ellipse and another 12 metres of deck supported by steel props on the south end of the bridge. Narrowest of the three bridges at only 3 metres wide; this means it has no room for segregated bike and pedestrian traffic. It also has no lighting on the bridge itself; though there are street lamps that lights up both the bridge for nighttime use. Note: The City was unable to give me the cost of this bridge as it was buried in the cost of the West LRT project, but in chatting with engineers the thought is the cost would be in the $6M range (this is the smallest of the three bridges).
The Bow Trail Bridge opened in December 2011, if you haven’t visited it, you should check it out for its spectacular view.
