Heart of the City Value Collection by Lauren Bavin

It was built by The City of Calgary in 1916 for $375,000. It replaced the MacArthur Bridge, a steel truss bridge built by a land developer called the Centre Street Bridge Company Limited. The MacArthur Bridge was destroyed by a flood in 1915. Centre Street Bridge was designed by John F. Green, featured an upper and lower deck, and large cast concrete lions on four massive plinths, two at each end of the bridge. The lions were cast by Scottish mason James L. Thompson, and were modelled after the brass lions at the base of Nelson's Column in Trafalgar Square, London. The upper deck, a reinforced concrete arch structure, spans 178 meters (584 ft) and is 15 meters (49 ft) wide. The lower deck, an "I" girders structure, runs for 150 meters (490 ft) and is 5.5 meters (18 ft) wide.
