The 164km Bridge With No End in Sight #engineering #howitworks #history #megastructures #technology

The Danyang–Kunshan Bridge is 164.8km long. You can’t see the end.

It’s the longest bridge in the world. But only 9km is over water. The other 155km goes over land. Why?

The ground is soft rice paddies that flood every year. So China built 2,000 pillars 80m deep and put the whole railway in the air.

10,000 workers. 4 years. 8 Hoover Dams of concrete. 65 Eiffel Towers of steel. Built for earthquakes and typhoons.

50 million people ride it yearly at 300 km/h. If you stand at one end, the curve of the Earth hides the other end.

The longest bridge on Earth… and it’s mostly over land.
