Engineering Feats

The Quebec Bridge stands as the world’s longest cantilever bridge, and this particular feature highlights its engineering brilliance. Spanning 987 m (3,239 ft), this feat was achieved through a meticulous design refined over the bridge’s tumultuous construction phases.

• Cantilever Design: Unlike traditional suspension or arch bridges, the cantilever structure uses a combination of suspended and balanced arms projecting towards the middle before connecting.
• Innovative Techniques: Engineers employed cutting-edge methods for the time, which included the first-ever use of steel trusses on such a large scale.

Construction Challenges and History

The journey of the Quebec Bridge’s construction is rife with obstacles, including catastrophic collapses. These challenges brought about vital changes in engineering practices.

• First Collapse (1907): Due to design flaws, the bridge tragically collapsed, leading to the loss of 75 workers’ lives. This incident emphasized the necessity for rigorous design checks.
• Second Collapse (1916): A repeat tragedy struck when the central span fell during installation, claiming 13 more lives.
• Completion (1919): After redesigns and stringent safety measures, the bridge was completed, standing as a testament to overcoming past failures.
