How can a bridge provide a walkable view of a national treasure?

Located in the Most Beautiful Small Town in Canada of Lunenburg, Nova Scotia, Anchored is a bridge to a view of the quaint port town’s colourful waterfront and its surrounding peninsula. Inspired by the town’s main attraction of Bluenose II, a replica of an early 1900’s racing ship and vessel that served as a provincial icon for Nova Scotia, the bridge presents itself as an historic ship anchored to a dock. The main structure is supported by 5 masts placed at the junctions between each section with sloping supporting cables that represent sails, and a steel tieback system that invokes a traditional capstan.

In order to achieve the “anchored” effect, the bridge had to be designed accordingly. The tensile forces of the steel tieback system (which is anchored by a concrete deadman) are equaled by the mast and tension cables.
