(CNN) — Cue the sweaty palms.
This week, workers were photographed installing the bridge's first piece of glass.
Set against dramatic landscapes in Zhangjiajie National Forest Park, the bridge is 430 meters long, six meters wide and hovers over a 300-meter vertical drop.
Construction on the bridge was originally expected to be finished at the end of 2015.
It's now set to open in May this year.
World's highest catwalk?
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.
Hanging above Zhangjiajie Grand Canyon, it will be able to hold up to 800 people at once.
Digital renderings of the bridge highlight the architectural firm's vision -- to build a glass structure that fades into the clouds.
Stunning as the view is, tourists will likely 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, according to witnesses.
Park officials said the damage was superficial and posed no threat to safety.
