Brave Men's Bridge —
It's called Haohan Qiao -- Brave Men's Bridge in English. The 300-meter-long overpass in Shiniuzai National Park in southern China has a bottom made of glass, allowing walkers to see the stomach-churning view below their feet.

Transformation —
Hovering 180 meters over ground, the span was originally made of wood. It's been converted to a glass walkway over the past year.

Just in time —
The bridge opened just in time for Golden Week, the biggest week for tourism in China. It begins on October 1 -- China's National Day.

Opening soon —
Also in Hunan Province, another glass-bottomed suspension bridge is planned for the Zhangjiajie Great Canyon area. When completed, the structure will be the world's highest and longest glass bridge.

Real life 'Pandora' —
Hunan Province, home to striking quartz cliffs and scenery, is a popular tourist destination. Part of it is said to have inspired the creation of "Pandora" in James Cameron's "Avatar."

Eiffel Tower —
