Cue the sweaty palms.

这可能会让你吓得手心出汗。

Travelers will soon be able to walk across the world's longest and highest glass-bottom bridge, which spans two cliffs in China's Hunan province.

游客们很快就可以体验这座世界最长最高的玻璃桥了。这座桥建在中国湖南省，横跨两座悬崖。

This week, workers were photographed installing the bridge's first piece of glass.

本周，工人被拍到正在桥上安放第一块玻璃。

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.

这座桥悬于半空，全长430米，宽6米，垂直高度达300米。站在桥上面可以一览张家界国家森林公园的壮丽景观。

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.

玻璃桥原本预计将在2015年底完工，最新消息称将于今年5月份开放。

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.

这座桥悬挂在张家界大峡谷的上空，一次可以容纳800名游客。

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.

尽管桥上美景震撼人心，游客们在行走的时候还是会小心翼翼。

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.
