The Longest Bridges in the World: The 164-Kilometre Crossing
The longest bridge on Earth runs for 164 kilometres — roughly the distance from London to Birmingham — carrying high-speed trains across the rice paddies and rivers of eastern China. The Danyang–Kunshan Grand Bridge is so long that calling it a 'bridge' almost understates it; it is an elevated railway the length of a small country. But the real engineering drama lies elsewhere: in the bridges that span the widest single gaps without touching the ground.
