Bridges have been a significant civil engineering accomplishment throughout history, with careful planning and construction ensuring their strength and resilience against traffic and weather. However, not all bridges are marvels of modern engineering, and some have been built in precarious locations, making them incredibly dangerous to cross. From old rope and wooden bridges to massive suspension bridges, these are the most hazardous bridges in the world. Those with a fear of heights would be relieved not to have to traverse them. Crossing these bridges can be perilous on foot or by car, representing some of the most dangerous feats of engineering in history.
