There’s a reason that a new walkway in China’s Hunan province is called “Haohan Qiao,” or Brave Men’s Bridge. Billed as the longest glass suspension bridge in world, the structure offers striking—and stomach-turning—panoramic views of the region’s jagged mountains and plunging valleys.

The 300-meter long overpass connects two cliffs at the popular Shiniuzhai National Geological Park. Its floor is constructed from two layers of glass, and is less than an inch thick. The walkway’s transparent bottom allows visitors to stare directly down into the rift below—a chasm 180 meters beneath their feet.

According to the South China Morning Post, the 300-meter-long bridge was originally made of wood. However, the park’s managers added a small section of glass last year and were so pleased with the outcome that they updated the entire thing.

The bridge’s opening coincided with Golden Week, a semi-annual week-long national holiday that starts on October 1 and commemorates the founding of the People’s Republic of China. Tourists from all over the country are expected to flock to Brave Men’s Bridge. However, whether they muster up the nerve to cross the glass bridge when they get there is a totally different story.
