About this chart

The Danyang–Kunshan Grand Bridge carries the Beijing–Shanghai high-speed railway for 164.8 km. It opened in 2010 and has been the longest bridge in the world since Guinness World Records designated it in 2011. Second is Taiwan's Changhua–Kaohsiung Viaduct at 157.3 km (2004). Japan's Kita–Yaita Viaduct on the Tohoku Shinkansen, at 114.4 km (1982), is the longest outside China and Taiwan, and the Tianjin Grand Bridge follows at 113.7 km.

Lengths here are total structure length including approach viaducts, and there is no standard way to measure a bridge. Most entries are high-speed rail or expressway viaducts rather than spans over water, and seven of the 15 are in mainland China. A ranking by main span would give a different order. The Hong Kong–Zhuhai–Macau Bridge (49.968 km, completed 2018) is the longest sea crossing listed, and the Lake Pontchartrain Causeway (38.4 km) is recorded by Guinness as the longest continuous bridge over water.

The data

Source: Wikipedia, List of longest bridges (Completed table; lengths converted from metres; sorted by total length). Retrieved November 4, 2026. Total length means the full length of the structure including approach viaducts, as listed by Wikipedia; there is no standard way to measure bridge length. Most entries are high-speed-rail or expressway viaducts, not spans over water. Ranking by main span (the longest unsupported span) would give a different order. Hong Kong-Zhuhai-Macau figure is the bridge-tunnel system's bridge length as listed.
