Human error. Construction on the Quebec bridge began in 1903, but miscalculations in planning meant that the actual weight of the bridge exceeded its carrying capacity. Quite simply, it was not strong enough for the job for which it was built. As the bridge neared completion in 1907, engineers noticed the structural problems but did not recognise how bad the situation was. The consulting engineer ordered all work to be halted on August 27, but work continued anyway. On 29 August 1907, the south arm and part of the central section of the bridge collapsed into the river in a matter of seconds. Of the 86 workers on the bridge at the time, 75 were killed.
A second collapse during construction in 1916 killed another 11 people. The bridge was finally completed in 1919.
