The world's longest glass-bottomed bridge opened in Zhangjiajie National Forest Park in China's Hunan province on Saturday (Aug 20).
But the 430m-long Zhangjiajie Grand Canyon Glass Bridge is not the only jaw-dropping glass walkway around.
For those not afraid of heights, here are other high-in-the-sky glass bridges around the world.
1. Tianmen Mountain skywalks, Hunan province, China
The Zhangjiajie glass-bottomed bridge is not even the only walkway with a see-through floor in the Zhangjiajie area.
Tianmen Mountain has three glass-bottomed skywalks that hug the cliff on the north, east and west faces of the mountain.
The first, named the "Walk of Faith", opened in 2011, while the latest, the 100m-long "Coiled Dragon Cliff" walk, opened earlier this August.
2. Brave Men's Bridge, Hunan province, China
Still in Hunan, the Shiniuzhai National Geological Park contains a glass-bottomed bridge - a suspension bridge, to boot.
Appropriately enough, the 180m-long bridge is known in Chinese as "Haohanqiao" or the Brave Men's Bridge.
On Aug 9, a couple made headlines around the world for dangling from the bridge on a platform to take their wedding photos mid-air.
3. Yuntai Mountain Glass Bridge, Henan province, China
The U-shaped walkway that wraps around Yuntai Mountain in Henan has a 68m-long glass-bottomed portion, which opened in September 2015.
Barely a fortnight later, the walkway was in the news again - this time when a glass pane cracked, giving tourists a nasty scare.
The Yuntai Mountain Geological Park management said that the glass floor was three layers thick and the damage affected only the top layer.
4. Yunduan Skywalk, Chongqing, China
In Chinese, "Yunduan" means "the end of the clouds". It is a fitting name for this 26.7m-long horseshoe-shaped observation deck, which extends from the top of a cliff in Longgang National Geographic Park. It opened in April 2015.
5. Grand Canyon Skywalk, Hualapai Reservation, United States
The Grand Canyon Skywalk is U-shaped observation deck that juts 21m beyond the edge of the Grand Canyon walk.
Open since 2007, the glass-bottomed skywalk offers a view of the gorge and the Colorado River more than 1km below. It is managed by the Hualapai nation, whose tribal lands are currently located in the US state of Arizona.
6. Glacier Skywalk, Alberta, Canada
From the Glacier Skywalk in Jasper National Park, visitors can stand on a glass platform 280m above the Sunwapta Valley to admire the snow-topped Canadian Rockies.
Designed to attract more tourists to the great outdoors, the skywalk opened in 2014.
7. Tower Bridge, London, United Kingdom
London's Tower Bridge, over the Thames River, is regularly raised to allow ships to pass beneath.
Since 2014, glass-bottomed walkways on both sides of the bridge give visitors a glimpse of the roads below.
