China opened the tallest bridge in the world, the Huajiang Grand Canyon Bridge in Guizhou. It was built in less than 4 years. 

It stands 625 meters (that's 114 giraffes, for the metrically challenged readers) above the Beipan River from deck to riverbed.

The 2890 meters long bridge (96 blue whale lengths), which has cut the time to cross the gorge from 2 hours to 2 minutes, also features a restaurant, a glass elevator, bungee jumping platform and a waterfall.
