Longest Bridges in the World

About This Dataset

The world's longest bridges ranked by total span length in kilometres. China dominates this list almost entirely, having constructed the vast majority of the world's mega-bridge projects since 2000 as part of an infrastructure investment programme of unprecedented scale. The Danyang-Kunshan Grand Bridge, which carries the Beijing-Shanghai High Speed Railway, is longer than the distance from London to Paris.

✨ AI Insight

The stark contrast between the lengths of the top two bridges and the rest of the list illustrates China's unparalleled commitment to infrastructure development. The Danyang-Kunshan Grand Bridge, at 164.8 km, dwarfs the Changhua-Kaohsiung Viaduct by over 7 km, while the gap to the third place Cangde Grand Bridge at 115.9 km is even more pronounced. This trend reflects China's focus on high-speed rail networks and urban connectivity, driven by rapid urbanization and economic growth. Meanwhile, the inclusion of the Bang Na Expressway from Thailand and the Lake Pontchartrain Causeway from the USA, both significantly shorter at 54.0 km and 38.6 km respectively, highlights the global disparity in bridge construction capabilities.
