1. The Québec Bridge Marker
This is the longest span cantilever bridge in the world, stretching 548.6 meters between the main piers. Completed in 1917, it is a remarkable engineering achievement. To overcome technical problems that had caused the collapse of an earlier span and the loss of 76 lives in 1907, Canadian engineers used nickel steel as a structural material and an innovative K-truss design. Designed and built by the St. Lawrence Bridge Company of Montréal, this impressive work is universally recognized as a symbol of engineering excellence.
French:
Ce pont cantilever possède la plus longue travée centrale du genre au monde, laquelle couvre une distance de 548,6 mètres entre les piliers principaux. Complété en 1917, il est reconnu comme un chef-d'oeuvre d'ingénierie. Pour résoudre les problèmes techniques qui avaient causé l'effondrement d'une travée et la mort de 76 personnes en 1907, les ingénieurs utilisèrent de l'acier au nickel comme matériau de construction et un système de poutres en K. Conçu et construit par la St. Lawrence Bridge Company de Montréal, cet imposant ouvrage symbolise mondialement l'excellence du génie canadien.
Erected 1997 by Heritage Trust of Nova Scotia.

2. The Québec Bridge Marker
1. Quebec Bridge - Wikipedia. In Canada, and many other countries, the aftermath of the Quebec bridge collapse still affects many today. This disaster showed what unquestionable power an engineer could have at the time in a project that was improperly supervised. As one result, Galbraith and others formed around 1925 what are now recognized as organizations of Professional Engineers. P.Engs are under different rules and regulations based on the organization to which they belong. (Submitted on March 6, 2015, by Barry Swackhamer of Brentwood, California.)
2. Quebec Bridge Disaster - The Canadian Encyclopedia. High above the St. Lawrence River, on a hot August day in 1907, a worker named Beauvais was driving rivets into the great southern span of the Quebec Bridge. Near the end of a long day, he noticed that a rivet that he had driven no more than an hour before had snapped clean in two. Just as he called out to his foreman to report the disquieting news, the scream of twisting metal pierced the air. (Submitted on March 6, 2015, by Barry Swackhamer of Brentwood, California.)
