Architects design ‘invisible’ glass bridge in Hunan Province, China

Warning: This is not for the faint-hearted. China’s latest glass-bottomed attraction will make you feel like you’re floating on air.

Warning: This is not for the faint-hearted.

China made headlines earlier this year when it opened a glass bottomed bridge over the spectacular Zhangjiajie Grand Canyon and now there are plans to open another in the World Heritage Site.

Architects want to replicate the popularity of the first bridge, the longest and highest in the world, that was forced to close 13 days after opening due to unexpected crowds.

Stretching 430 metres long, and perched 300 metres above the canyon below, the bridge has a capacity of 8000 people per day however officials say at its peak the demand was around 10 times this.

Now plans have been unveiled for another bridge that will this time be "invisible" by using mirrored stainless steel for its structure and black stone, that becomes reflective when wet, for the flooring.

The bridge will be built in the mountains that were the inspiration for the film, Avatar, and is said to cost over $6.8 million according to the Daily Mail. There will be two layers, one that won’t have a see-through floor for nervous tourists and a lower level that will be 100 per cent glass.

Every seven minutes water will be sprayed onto the bridge to create a temporary cloud between the two mountains.

Designed by Martin Duplantier Architecture, there are also plans for three pavilions over three storeys including a 360-degree lookout deck, cafe and accommodation.

Glass bottomed attractions have gained increasing popularity in China including a sightseeing platform that opened on the highest peak of China’s Shilin Gorge in May.
