Vietnam has just launched its latest tourist attraction for tourists with a fondness for heights. The Asian country has opened a glass-bottomed bridge suspended 150 m (490 feet) above a lush jungle. The Bach Long pedestrian bridge, which translates to white dragon, is set in the northwest Son La province. The bridge boasts a total length of 632 m, whereas the glass floor is made up of French-produced tempered glass. The bridge is strong enough to support up to 450 people at a time.
