Bridges are among the most remarkable feats of human engineering, connecting cities, countries, and continents. While many are known for architectural design, others are recognized due to their length, often spanning rivers, oceans, valleys, or swamps. However, defining the “longest” bridge isn’t always straightforward. Some are measured by total length (including approach spans), others by the main span, or elevation above terrain.
This article lists the Top 10 Longest Bridges in the World by total length, followed by the Top 10 Longest Bridges in the World by type, such as suspension, cable-stayed, arch, cantilever, and continuous truss bridges.
Types of Longest Bridges in the World
Before exploring the Longest Bridges in the World, it's important to understand the different types of bridge structures:
| Types of Longest Bridges in the World | |
| Bridge Names | Key Features / Description |
|
Viaducts |
Long bridges with a series of spans; ideal for high-speed rail and highways |
|
Suspension Bridges |
Deck hangs below cables suspended between towers; allows for very long spans |
|
Cable-Stayed Bridges |
Cables run directly from one or more towers to the deck; modern and efficient design |
|
Arch Bridges |
Curved arch structure bears loads through compression; visually strong and durable |
|
Cantilever Bridges |
Horizontal beams extend into space, supported at only one end; allows construction without falsework |
|
Continuous Truss Bridges |
Connected truss framework spans long distances without hinges; ensures uniform load distribution |
Longest Bridge in the World - Danyang-Kunshan Grand Bridge
Spanning approximately 165 kilometers (102.4 miles), the Danyang-Kunshan Grand Bridge in China is the Longest Bridge in the World. It’s a viaduct, constructed primarily for high-speed rail, stretching across the Yangtze River Delta.
The Danyan Kunshan Grand Bridge supports the Beijing-Shanghai High-Speed Railway and crosses rice paddies, lakes, and river systems. Built to withstand earthquakes and extreme weather, the project employed over 10,000 workers and took four years to complete. It opened in 2011 and showcases China's dedication to infrastructure-led growth.
