Scariest Bridges Around the World

Vine Bridges

Like the monkey bridges of Vietnam, the vine bridges of Iya Valley, Japan are a cultural tradition. However, no one is quite sure who created these intricate and delicate structures. They are believed to be at least 900 years old. There is evidence that the valley was once home to 13 of these woven vine and plank bridges. Today, however, only 3 survive. Despite the fact that modern engineers have reinforced these ancient bridges with steel, the 45-foot drop into the valley below is still a bone-chilling experience for tourists.
