One of the world's greatest engineering feats, the four-mile Nanjing Yangtze River Bridge is truly a sight to behold. It is double-decked, with the China National Highway up top and the Beijing-Shanghai Railway on the bottom. Completed in 1968, the bridge carries a massive 80,000 vehicles a day, in addition to 190 trains. If you're cruising the Yangtze River, this bridge is a must-see attraction.
We bet you're waiting to hear what danger might befall you if you cross the bridge. This is definitely a dangerous spot, but not for the reasons you might think. The Nanjing Yangtze River Bridge is actually the most frequent suicide site in the world, with more than 2,000 people ending their own lives there since its opening in the 60s. It's definitely not somewhere we've got on our bucket lists.
