A terrifying wooden bridge in China has just been replaced by a glass one. This, the world?s longest glass-bottomed walkway, is located in Shiniuzhai Geopark in Hunan, and spans 300m (984f) and is 180m (590f) above ground. The floor is made of double-layered glass that is 24mm (0.94in), and is reportedly 25 times stronger than regular window glass.
The bridge had previously been made of wood, linking the two peaks of Stone Buddha Mountain, but 11 engineers working 12 hours a day converted it to glass. Previously, you were considered brave if you steeled yourself to cross the wooden walkway; now, with its glass bottom, the bridge is already being referred to as ?hero bridge.?
