Seal Island Bridge, Highway bridge in Cape Breton, Canada
The Seal Island Bridge features eight steel box truss spans supported by reinforced concrete piers, crossing the Great Bras d'Or channel of Bras d'Or Lake.
The construction of this $6 million infrastructure project began in 1960 as part of the Trans-Canada Highway initiative and reached completion in 1961.
The bridge replaced two ferry routes, changing the traditional maritime transportation patterns of local communities and reshaping regional connectivity patterns.
Regular inspections and maintenance work ensure the bridge can support over 7,500 vehicles daily, with occasional closures during strong winds for safety measures.
Between 2001 and 2004, the bridge underwent major renovations that introduced a precast concrete deck system, earning the Lieutenant Governor's Award for Engineering Excellence.
