About This Dataset

Longest Bridges in the World

Every bridge in the top four carries high-speed rail across soft or flood-prone ground, which is why they run so long: a continuous viaduct proved cheaper and more stable than raising embankments. The Danyang-Kunshan Grand Bridge on the Beijing-Shanghai line stretches 164.8 km, more than four times the Lake Pontchartrain Causeway, which remains the longest bridge over open water.

Analysis

Danyang-Kunshan Grand Bridge heads the table on 164.8, ahead of Changhua-Kaohsiung Viaduct (157.3) and Tianjin Grand Bridge (113.7) in Total Length (km). The total is spread widely: even Danyang-Kunshan Grand Bridge accounts for only 23.8% of the 8 combined. Only 3 of the 8 reach even half the leader's figure (82.4 or more).
