Set over the Bow River in the town of Banff — Canada’s first national park — this slender 370-foot long timber bridge serves pedestrian traffic and provides a new sanitary crossing replacement.
The 270-foot clear span - perhaps the longest of its kind for a timber bridge - is formed from two 130-foot tapered haunch girders, cantilevering from either side to support a central 111-foot suspended span. A replaceable modular timber deck sits atop twinned Glulam beams which grow to six feet deep. A custom built tuned mass damping system was implemented to help achieve the slender 13-foot wide deck section and to deal with vibrations from pedestrian loading.
