Temporary measure: a suspension bridge over an abyss scares people from all over the world (2 photos + 2 videos)
The structure has no towers or foundations for support, relying on just four steel cables to support vehicles weighing up to 45 tons. 
A suspension bridge that spans 150 meters over the Dadong River Gorge in the Chinese city of Chongqing has been dubbed the "scariest suspension bridge" in the world due to its unsafe appearance.
For the past few years, videos have been popping up on social media showing heavy construction vehicles driving across a narrow, flimsy-looking bridge suspended some 300 meters above a wide river gorge. Despite being 240 meters long, the structure has no towers or foundations for support, relying on just four steel cables to support vehicles weighing up to 45 tons. It’s only wide enough for one car to pass through, and despite safety nets on each side, one misstep could spell disaster.
Luckily, the Dadong River Gorge Suspension Bridge in Chongqing’s Wulong District is a temporary project designed to facilitate the construction of an even more impressive piece of infrastructure, the Shuangbao Bridge. Once completed, it will be the world’s largest double-arch bridge. But in order to build this grand structure, the workers had to reach a small mountain that would eventually become a support for the central arch supports. And then they came up with the idea of a temporary suspension bridge.
The so-called "world's scariest suspension bridge", which stretches 240 meters across the western side of a huge gorge, is 12 meters wide. Technically, this is not a problem, since only trucks and construction equipment working on the Shuangbao Bridge drive on it, but that does not mean it is easy to drive across.
