A bridge is defined as “a connecting, transitional, or intermediate route or phase between two adjacent elements, activities, conditions, or the like.” Bridges are important for any kind of transportation because they provide safe passageway for people traveling over bodies of water, valleys or roads. Even though bridges are precisely engineered structures with strength that can support hundreds and even thousands of cars and automobiles, they are sometimes traumatizing to look at and scary to cross. There are a number of bridges in the world that certainly cause travelers to fear for their lives, most likely causing several panic attacks.

The Glass Skywalk at China’s Tianmen Mountain in Zhangjiajie National Park is the world’s longest glass-bottom bridge stretching 1,410 feet and spanning two cliffs over a 984-foot drop. The footbridge was designed by Israeli architect Haim Dotan, who says the bridge can hold up to 800 people at once. The Skywalk also stole the title of highest bungee jump from Macau Tower’s 764-foot-high attraction. Eshima Ohashi Bridge is another scary bridge because it’s more like a roller coaster. The concrete road bridge spans one mile across Lake Nakaumi in Japan, connecting the cities Matsue and Sakaiminato. Eshima Ohashi Bridge has a gradient of 6.1% on one side and 5.1% on the other, making for an interesting roller coaster ride.
