Tourists attempt to cross China’s first glass-bottomed suspension bridge

The whole contraption hangs between two lush cliffs in Shiniuzhai National Geological Park, giving travelers an astonishing view below.

The bridge was originally made of wood, then added a section of glass to the bridge past year.

Stretching almost a quarter of a mile across a nearly 600-foot deep chasm in China’s Hunan province, is the Haohan Qiao bridge. But in a bid to introduce a more thrilling experience for tourists, the floor of the bridge was changed to a glass surface. Specifically, the glass is three-quarters of an inch thick and is treated to be extremely resistant to both bending and shattering.

It took a team of 11 engineers who carried out the work, adding new steel cables and struts for support before replacing the wooden slats with panes of glass. I’d be a bit nervous about walking on a bridge that was 590 feet in the air and had a glass bottom no matter where it was.

The glass is 25 times stronger than normal, and the steel frame would keep people from falling even if the glass did break. The Grand Canyon in Arizona boasts a glass walkway, and other glass-floor attractions exist around the world.
