Which railway bridge in China is part of the Beijing–Shanghai high-speed line and is the world’s longest bridge?

The Danyang–Kunshan Grand Bridge is the world’s longest bridge, stretching about 164.8 kilometres along China’s Beijing–Shanghai high-speed railway.

The viaduct runs through Jiangsu Province between Danyang and Kunshan, including areas of rice paddies, waterways, lakes, and developed land. It opened in 2011 as part of the high-speed rail route, which greatly reduced travel time between major Chinese cities.

Most of the structure is an elevated concrete viaduct rather than a single dramatic crossing over open water. That distinction explains why photographs can make it look less like a conventional bridge while it still holds the overall length record.

It is sometimes confused with the Tianjin Grand Bridge, another enormous Chinese railway viaduct. Tianjin Grand Bridge is also among the world’s longest bridges, but it is shorter than Danyang–Kunshan.
