Millennium Bridge -

The Millennium Bridge in London was opened to the public on June 10, 2000, connecting St Paul's Cathedral with the Tate Modern art gallery. Everything seemed perfect, until "wobbling" occurred when people walked across it. The phenomenon gained attention because the wobbling was significant enough to make people feel uncomfortable and unsteady while walking on the bridge.

Quebec bridge collapse, Canada -

The collapse of this bridge happened twice—first in 1907, and then again in 1916—due to inadequate verification of initial calculations during the early planning phases. The bridge was essentially designed to bear a load far beyond its actual capacity, resulting in these catastrophic failures.

Banqiao Dam -

In 1975, a combination of factors, including bad design, inadequate maintenance, faulty construction practices, and the impact of a typhoon (depicted), led to the failure of this Chinese dam. The aftermath of the dam breaking resulted in a devastating loss of 230,000 lives, and forced approximately 11 million people to relocate.
