It's touted as the "world's highest and longest" glass-bottom bridge, elegantly stretched between two mountain peaks in central China's Hunan province.


And as of this weekend, it's open to visitors. Now, one can walk the 470-yard length of the glass bridge, which is positioned a vertigo-inducing 328 yards above the ground, as China's state-run news agency 


The bridge is located in the Zhangjiajie National Forest, where the otherworldly, plummeting mountain faces reportedly provided inspiration for the forest setting in the film "Avatar."


"I wanted to feel awe-inspired by this bridge. But I'm not afraid — it seems safe!" visitor Wang Min told Agence France Presse.


The bridge cost $3.4 million dollars to construct, and is "paved with 99 panes of three-layered transparent glass," according to Xinhua. Only 800 people are allowed on the structure at a time, the news agency added.


And cameras, selfie sticks and stilettos are not permitted on the bridge, as AFP reported.


It was designed by Israeli architect Haim Dotan, who told Wired that he initially rejected the project: "[The developer] asked me, 'What do you think about a bridge from here to there?' And I said, 'No.' ... He looked at me and said 'Why, what are you talking about?' And I said, 'Why do you want a bridge? It's too beautiful."


But after more pressure from the developer, he gave in, as Wired reported. "I told him, 'We can build a bridge but under one condition: I want the bridge to disappear.' "


But the big question for many visitors is whether or not it's safe — especially after an "alarming glass bridge cracking incident at the Yuntai mountain in northern Henan in 2015," as AFP reported.


Prior to the Zhangjiajie opening, Chinese authorities tried to reassure visitors by holding highly-publicized safety tests for the media. For example, participants were invited to bash in the glass panels with sledgehammers. In one such demonstration, the BBC's Dan Simmons shatters the top layer of glass on the first swing, but fails to damage the lower layers after striking the panel a dozen times.


"Do you know what? I think this might be safe," Simmons said while laughing, winded from sledgehammering. Authorities also held an event where they drove a car over the bridge.


China has quite a penchant for glass-bottomed bridges and skywalks — and while officials say this is the longest, similar structures have been appearing around the country.


"Glass bridges in China have been a popular craze for the daring photo opportunities they provide," the BBC reported. "Events like mass yoga displays and even weddings have been staged on several such bridges."


Architect Keith Brownlie told the BBC that it's all about the "thrill."


"It is the relationship between emotionally driven fear and the logical understanding of safety," Brownlie said. "These structures tread the boundary between those two contrasting senses and people like to challenge their rational mind in relation to their irrational fear."
