Longest Bridge in the World: Where Record-Breaking Engineering Meets Stunning Landscapes

Ask most people to name the world’s longest bridge, and you’re likely to get a confident answer like the Golden Gate Bridge or the Brooklyn Bridge or some other famous landmark plastered across postcards and movies. But the world’s longest bridge is not a tourist attraction or an architectural icon in the traditional sense. It is the Danyang–Kunshan Grand Bridge, a 164.8-kilometre engineering marvel on China’s Beijing–Shanghai High-Speed Railroad.

Day after day, trains carrying commuters, students, and business travellers glide across its length, crossing wetlands, fish farms, rivers, canals, and endless paddy fields. Most passengers never realise they are travelling over a structure that holds a world record.

Its quiet existence is part of what makes it remarkable. Unlike bridges celebrated for dramatic skylines or dizzying heights, the Danyang–Kunshan Grand Bridge, known as the longest bridge in the world, was built for efficiency, speed, and scale. It is a testament to modern engineering on a level so vast that it often goes unnoticed, a record-breaking structure hiding in plain sight, carrying people across one of the busiest rail corridors on Earth.

These four titles get mixed up constantly, and each one describes a different kind of record. Keep reading since every one of them is explained below.

What Is the Longest Bridge in the World?

Danyang Kunshan Grand Bridge is the longest bridge in the world. Running 164.8 kilometres through Jiangsu Province, the Danyang Kunshan Grand Bridge (also written Danyang–Kunshan) carries the  –Shanghai High-Speed Railway from the coast into the country’s interior. Construction began in 2006 and finished in 2010, at a cost of roughly US$8.5 billion, with the line opening to passengers the following year.

Rather than crossing a single river or valley, the bridge threads through cities, lakes, rice paddies and wetlands on more than 9,500 concrete piers, allowing bullet trains to hold speeds of up to 300 km/h without slowing for the ground below.

For travellers, this is precisely what makes it worth experiencing: a window seat on the Beijing–  line offers an uninterrupted view over the Yangtze Delta countryside for nearly two hours, covering scenery that would otherwise take a full day to see by road. The bridge has held its Guinness World Record since 2011, and no other structure has come close to challenging it since.

Can You Visit the World’s Longest Bridge?

Yes, and the simplest way is to book a seat on the Beijing–Shanghai High-Speed Railway journey through China. Any train running this route crosses the Danyang–Kunshan Grand Bridge as a matter of course, so no special ticket or detour is required; a window seat on the Nanjing–Suzhou stretch is enough to appreciate its scale.

As the bridge is elevated and built for 300 km/h running, there is no pedestrian access or dedicated viewing platform along most of its length. The experience is meant to be had from inside the train, watching wetlands and rice fields drift by beneath you.

Top 10 Longest Bridges in the World

Length alone doesn’t tell you much unless you know what each bridge actually carries, why it was built that long, and what makes it worth knowing about. Here’s the full list.

Danyang Kunshan Grand Bridge: China, 164.8 km

The reigning record-holder since 2011, this elevated viaduct carries the Beijing–Shanghai High-Speed Railway across Jiangsu’s lakes, wetlands, and rice paddies on more than 9,500 concrete piers. Trains cross at up to 300 km/h without a single ground-level obstruction. For travellers, it’s the rare record you can experience simply by booking a train ticket rather than a special tour.

Changhua-Kaohsiung Viaduct: Taiwan, 157.3 km

The Changhua–Kaohsiung Viaduct in  was engineered so that bullet trains could stop safely mid-span during an earthquake, a genuine priority in one of the world’s most seismically active regions. It crosses flood-prone farmland and urban corridors, keeping western Taiwan connected at full speed year-round.

Tianjin Grand Bridge: China, 113.7 km

The Tianjin Grand Bridge, another segment of the Beijing–Shanghai line, runs between Langfang and Qingxian using modular precast sections that considerably sped up construction. It allows trains to bypass rivers, roads and flood zones north of Tianjin, keeping the capital-to-Shanghai run smooth and largely invisible to the passengers riding it.

Cangde Grand Bridge: China, 105.8 km

The Cangde Grand Bridge crosses the Wei River on more than 3,000 seismic-resistant piers, forming another critical link along the world’s busiest high-speed rail corridor. It is less well known than its record-holding neighbours, but structurally, it is among the most heavily reinforced sections of the entire route.

Weinan Weihe Grand Bridge: China, 79.7 km

The Weinan Weihe Grand Bridge, part of the Zhengzhou–Xi’an High-Speed Railway, briefly held the title of the world’s longest bridge before the Beijing–Shanghai corridor overtook it. It spans the Wei River, a major tributary of the Yellow River, using continuous beam and box-girder construction to keep central China’s rail network running at speed.

Bang Na Expressway: Thailand, 54 km

The Bang Na Expressway in  is the longest bridge built for road vehicles anywhere in the world. This elevated Bangkok tollway floats above existing streets rather than crossing water, built with 1.8 million cubic metres of concrete to ease congestion across Metro  without touching a river, sea or valley.

Beijing Grand Bridge: China, 48 km

The Beijing Grand Bridge guides bullet trains through the capital’s outskirts, bypassing dense road traffic and shifting terrain. Built with prefabricated box girders for faster assembly, it forms the final high-speed link between Beijing and the wider Beijing–Shanghai corridor.

Dhaka Elevated Expressway: Bangladesh, 46.7 km

The Dhaka Elevated Expressway, completed in 2023, is Bangladesh’s first large-scale elevated expressway, built to bypass chronic gridlock in one of the world’s most densely populated cities. It reflects a wider shift in global infrastructure: record-length engineering is no longer a China-only story, with developing economies now building at genuinely global scale.

Metro Manila Skyway System: Philippines, 39.2 km

The Metro Manila Skyway System, built in stages since the 1990s and completed in 2021, snakes through the  capital, linking with the NAIA Expressway to reduce journey times across the city. It stands as a practical, decades-long answer to Metro Manila’s chronic traffic congestion, rather than a single record-chasing project.

Lake Pontchartrain Causeway: USA, 38 km

Finally, the Lake Pontchartrain Causeway in Louisiana, made up of two parallel spans opened in 1956 and 1969, holds a separate Guinness World Record as the longest continuous bridge over open water, distinct from total length. Pre-stressed concrete pilings and a mid-span drawbridge allow it to endure hurricanes and heavy daily traffic alike.

Biggest Bridge in the World vs Longest Bridge in the World

“Biggest bridge in the world” and “largest bridge in the world” are search terms people use interchangeably with “longest,” and the good news is, they all point to the same structure. The Danyang Kunshan Grand Bridge is the record-holder, whichever phrase you search, because “big” and “large” here mean total length, not height, width, or how much material was used to build it.

If you ever see a bridge called the biggest by weight of steel or concrete, that’s a different and far less searched record altogether.

Highest Bridge in the World

Huajiang Grand Canyon Bridge

The title of highest bridge in the world changed hands in September 2025. China’s Huajiang Grand Canyon Bridge opened in Guizhou Province with a deck sitting 625 metres above the Beipan River, nine times the height of the Golden Gate Bridge’s deck, overtaking the nearby Duge Bridge, which had held the record at 565 metres since 2016. The suspension bridge stretches 2,890 metres in total with a 1,420-metre main span, cutting a journey that once took two hours by mountain road down to about two minutes.

It’s already become a destination in its own right, with a glass skywalk, a sky café perched roughly 800 metres above the canyon floor, and a bungee-jumping platform for travellers who want to feel the drop rather than just see it.

Tallest Bridge in the World

Millau Viaduct

“Tallest” and “highest” sound identical but measure different things. Tallest refers to a bridge’s own structural height, from its lowest support to its highest point, rather than the drop to the ground below. By that measure, France’s Millau Viaduct remains the record-holder, with its tallest pier and mast rising 343 metres above the Tarn Valley, 19 metres taller than the

Designed by engineer Michel Virlogeux and architect Norman Foster and opened in 2004, its slender cable-stayed profile has made it one of the most photographed bridges in Europe, and a scenic stop for travellers exploring southern France through France tour packages.

Top 10 Highest Bridges in the World

Nine of the world’s ten highest bridges sit in or around Guizhou province, a mountainous pocket of southwestern  that Chinese state media has nicknamed the “world museum of bridges.” Outside China,  ‘s Baluarte Bridge is the highest of its kind, and Colorado’s Royal Gorge Bridge remains the highest bridge in the United States.
