This bridge is made of Glass.
It’s the world longest glass-bottom bridge in the world.
I can tell you: What a terrifying walkway!
You can visit it at The Yuntai Mountain Geological Park, in China (or it is better not and I’ll tell you why).
The reason is simple: the glass on the floor started cracking.
From the The Yuntai Mountain Geological Park they say that’s it no compromises the Global security of the bridge. But .. Will you walk on a broken glass bottomed bridge? Can you imagine the wind passing trough the cracks and the vibrations? 🙂
