Tourists were invited to smash sledgehammers into the highest and longest glass bridge in the world, which is suspended 300 meters above a canyon at Zhangjiajie's Tianmen Mountain National Park, to test its strength and safety on Saturday.

Some 30 local citizens and tourists were asked to swing the 12-pound hammers at the structure to test its durability.

According to 9news, one glass panel was repeatedly struck by visitors to ensure that it could safely hold its tourists, even when compromised. Then, after several blows from the public, a two-ton SUV vehicle, which can hold up to 11 people, ran over it as well. However, there were still no breaks, although a few cracks were left on the topmost layer.

"Even if the glass cracks, it will not break into pieces. Pedestrians can still walk on it," Chen Zidong, an official from the park told the South China Morning Post.

The bridge is made up of 99 panes of three-layered tempered glass, each three by 4.5 meters and 15 mm thick. Destroyed pieces can also be replaced with new ones.

The event was intended to assuage fear and brush off rumors over the risky-looking glass bridge. Last year, many tourists panicked after they discovered some cracks in a glass bridge at Yuntain Mountain.

The 430 meter long bridge is a creation of Israeli architect Haim Dotan. The glass bridge, which can hold up to 800 individuals, reportedly costs 250 million yuan (around $37.57 million) to build. It is scheduled to open to the public next month.
