A very special attraction recently opened in the Shiniuzhai Nature Park in the Japanese province of Hunan: the world's longest bridge with a glass floor! It is 300 meters long and leads over an abyss that is up to 180 meters deep. However, there is a problem: although the glass used is 25 times stronger than conventional window glass, few tourists dare to cross the bridge. That's why the building is unofficially called "Hero's Bridge". Originally a wooden bridge led across the valley. Then the park management thought about a way to attract more visitors and first replaced part of the bridge with glass. It was then completely rebuilt this year, when eleven engineers used the new glass panels twelve hours a day. They are so stable that you could jump around on them without breaking them. And even if something were to happen, the steel construction would prevent a fall into the depths. Incidentally, the Heroes' Bridge will soon be replaced as the longest glass bridge in the world. One is already under construction in Zhangjiajie National Park and will be 430 meters long.
