China’s Danyang–Kunshan Grand Bridge spans 164.8 kilometers (102.4 miles), making it the longest bridge in the world. Completed in 2010 and operational since 2011, the bridge plays a vital role in the Beijing–Shanghai High-Speed Railway, supporting bullet trains traveling up to 300 km/h. Built over a complex network of lakes, rivers, rice paddies, and urban sprawl, the bridge required over 10,000 workers and four years to complete. It’s designed to withstand typhoons, magnitude-8 earthquakes, and even direct hits from naval vessels—cementing its place not just as a record-breaker, but a masterpiece of civil engineering. #EngineeringMarvel #LongestBridge #ChineseInfrastructure #HighSpeedRail #CivilEngineering
