This bridge is an extremely long-span cantilever deck truss bridge, and one of the few surviving heritage bridges in this area. Construction took place from 1956 to 1960. During construction there was a tragic collapse on June 17, 1958. According to Wikipedia, "On June 17, 1958, as a crane stretched from the north side of the new bridge to join the two chords of the unfinished arch, several spans collapsed. Seventy-nine workers plunged 30 meters (98 ft) into the water. Eighteen were killed either instantly or shortly thereafter, possibly drowned by their heavy tool belts. A diver searching for bodies drowned later, bringing the total fatalities for the collapse to nineteen. In a subsequent Royal Commission inquiry, the bridge collapse was attributed to miscalculation by bridge engineers. A temporary arm, holding the fifth anchor span, was deemed too light to bear the weight." Contractors for the bridge were the Dominion Bridge Company of Montréal, Québec, Kiewit Raymond, and John Laing and Son.
