The world's longest bridge that cost an eye-watering £6.58 billion and is 102.4 miles long

The Danyang–Kunshan Grand Bridge in China, renowned as the world's longest bridge, is a marvel of modern engineering, stretching an astounding 102.4 miles (165 kilometres). 

This impressive feat of infrastructure, which cost a staggering £6.58 billion to construct, is a key part of the Beijing-Shanghai High-Speed Railway.

Completed in 2010 and officially opened in 2011, the bridge traverses a variety of terrains, including rivers, canals, lakes, and expansive rice paddies. 

Its design and construction were overseen by the China Road and Bridge Corporation (CRBC), employing thousands of workers and taking approximately four years to complete.

The bridge primarily serves high-speed trains, significantly enhancing travel efficiency between Beijing and Shanghai. 

It reduces the travel time between these major cities to just about five hours, revolutionising transportation in the region. 

The Danyang–Kunshan Grand Bridge can withstand extreme weather conditions, including earthquakes and typhoons, ensuring its durability and safety for years to come.

Constructed using over 450,000 tons of steel and 2,300,000 cubic meters of concrete, the bridge features more than 2,000 pillars and a robust support structure designed to accommodate the high-speed rail's demands. 

Its construction required innovative techniques and advanced engineering solutions to address the challenges posed by the varied landscape it spans.

Beyond its functional benefits, the bridge has also become a symbol of China's rapid advancement in infrastructure and technological prowess.

It attracts engineers, architects, and tourists from around the world, eager to witness this extraordinary landmark.
