The world's highest and longest glass bridge is set to open in China soon but would you walk on it?

The 430m bridge is suspended 300m over a canyon in Zhangjiajie National Park, Hunan province, China, and cost 250 million yuan (S$51.7 million) to construct.

On Saturday, Chinese officials conducted a safety test ceremony (left) and finished putting the final touches to the bridge ahead of next month's opening.

The skyway, which offers a captivating view of the scenic Tianmenshan National Forest Park in Hunan province, can hold up to 800 visitors at a time.

Designed by Israeli architect Haim Dotan, the glass-bottom bridge will also feature the world's highest bungee jump and serve as a runway for fashion shows.

But experience suggests that tourists are likely to tread carefully.

In October last year, cracks appeared in a mountainside glass walkway in Yuntaishan Scenic Park, in China's central Henan province, just two weeks after opening.

The incident sent visitors running and screaming in panic.
