Imagine the St. Lawrence River at the end of the 19th century—a powerful and untamed artery that bisects Quebec. The construction of the Quebec Bridge was meant to be the ultimate triumph of human will and the pinnacle of civil engineering at the time. Yet, this project went down in history not only as the longest cantilever bridge in the world, but also as one of the darkest chapters in engineering history.
In this documentary, we delve into an era of boundless ambition and fatal errors. Discover the story of Theodore Cooper, the "infallible" genius of New York, whose pride and miscalculations led to the 1907 disaster. We reconstruct the chronology of those terrifying 15 seconds when 19,000 tons of steel plunged into the abyss, taking the lives of 75 workers, including the elite ironworkers of the Mohawk community of Kahnawake.
But the story of the Quebec Bridge is not just a chronicle of collapse. It is an epic of incredible resilience. Relive the second attempt in 1916, when a new structure, twice as heavy, once again defied the river. We recount the dramatic moment of the lifting of the 5,000-tonne central span, which, before the eyes of a crowd of 50,000 spectators, broke apart and disappeared into the depths of the river.
Why was this project called "cursed"? How did Canadian engineers find the strength to launch a third attempt in the midst of the First World War? And why, even today, does every Canadian engineer wear a simple iron ring on their little finger?
The Quebec Bridge still stands today as a monument to human triumph built upon the ruins of pride. It is the story of the birth of a professional ethic through tragedy, and of how steel taught humankind humility in the face of the laws of nature. From the first plan to the last rivet, walk this path with us.

J'ai lu plusieurs commentaires négatifs, moi, je trouve cette vidéo très bien, l'histoire est fidèle à la réalité.
Bravo pour cette vidéo. Je vais assurément la partager!
PS: J’avoue avoir eu plusieurs sourires à voir ces erreurs visuelles générées par l’IA. Appel à ceux que ça intéresse: J’aurais aimé voir un travail similaire contenant des images d’archives ;) .
