Danyang Kunshan Grand Bridge
As the name suggests, this is indeed a grand bridge. At 164-kilometer-long, the Danyang Kunshan is currently the longest bridge in the world. It’s located in China and runs from Shanghai to Nanjing in Jianpsu province.
This is not only the longest bridge in the world but probably the most expensive one, as its construction cost around $8.5 billion. The construction of the bridge took four years and was completed in 2010, and it was another year before it finally opened for traffic.
