Seal Island Bridge
From Wikipedia, the free encyclopedia
The Seal Island Bridge is an arch truss bridge crossing the Great Bras d'Or channel of Bras d'Or Lake in Victoria County on Nova Scotia's Cape Breton Island.
With the third longest bridge span in the province, the Seal Island Bridge opened in 1961 as part of the Trans-Canada Highway project, the structure carries 2 traffic lanes of Highway 105, connecting Boularderie Island to the north side of the channel.
The bridge crosses part of the channel on a causeway connecting the north shore of the channel to Seal Island, a small wooded island. It consists of eight steel truss spans: a main arch of 152 m (500 ft), two side spans of 106 m (350 ft), and five approach spans of 76 m (250 ft).
