Top 10 Longest Bridges in the World You Must See

The oldest bridges were natural structures, composed of logs, vines, or stone. The Romans created and taught ways to build bridges that could go further and survive longer. In a new era, the Brooklyn Bridge in New York is a fine example of the new kind of suspension bridge. These bridges are more than a way to pass over a gap in your way; they are well-known in the world and tell you a lot about what the past and the time they were made were like. Now, for the 10 longest bridges in the world, see how mankind keeps on moving past the old and on to the new way of building.

1. Pontchartrain Causeway

In southeast Louisiana, it is a famous work that used prestressed concrete and pre-made bits on a large scale. It's one of the longest bridges that goes over water in the world. It was made as a two-lane bridge. A second part was added in 1969. It is made of a bunch of block-like pieces that are on piles all along. Two of these have bascule spans on the north side so ships can get through. The causeway shows the skill of the USA in the mid-1950s, as it can withstand the winds of the hurricane.

• Length: 38 km
• Location: USA
• Completed: 1956

2. Metro Manila Skyway 

The Metro Manila Skyway System is a highway that goes over the others and links the north Luzon express way NLEX, and the south Luzon express way SLEX. It also gives a way to the Ninoy Aquino International Airport and by the NAIA expressway. This is the first highway in the Philippines that is all built up away from the ground; it has no places at the level of the ground. The highway has 4 to 6 lanes, and it has concrete bridges that go over the streets and the buildings, and the forests. The way is helping people not get stuck in traffic, and this gives us a way to see how the large cities will grow up and not out, and this will be a way for the highways of the future.

• Length: 39.2 km
• Location: Philippines
• Completed: 2021

3. Beijing Grand Bridge

It covers 48 km it is one of the world's longest bridges, called the Beijing Grand Bridge. It is for a train line called high speed the high-speed Shanghai line. The bridge goes over a busy part of the city. There are rivers and many buildings all along the way. It suits well with the city's mix of transport it does not take much extra space. They used thin support pillars and lifted tracks to save land. Most of the bridge was built in a factory and then sent to the site. This speed up the work and ensured the work was strong and was good quality.

• Length: 48 km
• Location: China
• Completed: 2010

4. Bang Na Expressway

The Burapha Withi Expressway is one of the longest road bridges in the world. It helps fix the big traffic jam problems on the busy city roads with smart design. The bridge pays to show how new ideas are changing how we build city roads. It has many layers of roads, with a height of about 42 meters, held up by strong H-shaped columns made from concrete. In two parts, the six-lane bridge gets bigger to make space for twelve toll lanes. The plan used a design-build way of doing things, which means the plus and play were done at the same time. The bridge was made by Jean M. Muller with Asian Engineering Consultants, and Louis Berger gave it technical help. The build was done by Ch. Karnchang and Bilfinger & Berger.

• Length: 54 km
• Location: Thailand
• Completed: 2000

5. Hong Kong Zhuhai Macau Bridge

It is the world’s longest sea. The bridge has many parts. There are three cable bridges, a 6.7 km tunnel under the sea, and four man-made islands that join the bridge and tunnel parts. At the Hong Kong end is a 9.4 km road on tall supports and a 1 km tunnel under a hill. The Zhuhai side has a 13.4 km road with tunnels and raised roads that join the bridge to the city. This project is a big win for engineers. They used new ways to build in the sea and underwater.

• Length: 55 km
• Location: China
• Completed: 2018

6. Weinan Weihe Grand Bridge

The Weinan Weihe Grand Bridge is a very long and well-built bridge. It crosses the Wei River twice. It crosses small rivers, roads, and train lines. The bridge was built to link the High-Speed Railway. This made fast travel easier. Ten thousand laborers built the bridge. They put 2.3 million cubic meters of concrete and 45,000 tons of steel. The bridge is built with a very strong beam and girder style that proves China's new skill for a long and safe bridge for fast trains.

• Length: 79.7 km
• Location: China
• Completed: 2008

7. Cangde Grand Bridge

It is on the Beijing-Shanghai high-speed railway. It crosses rivers and wet ground. It is held up by 3092 big poles. The bridge was built with precast construction. This helped the builders to finish it fast and to make it durable and long-lasting. Because the rail is built on high poles with deep bases, the ground does not change too much. The design lets trains go through touchy natural areas without hurting the place. The bridge keeps animals and the land safe, and it also shows that modern train projects can be safe for nature while still being good for mankind.

• Length: 105.8 km
• Location: China
• Completed: 2010

8. Tianjin Grand Bridge

The Tianjin Grand Bridge is big in China, built for the high-speed train from Langfang to Qingxian. Instead of building lots of small bridges to go over roads and railways, engineers made one really long bridge. This made it save land and take less time to build. The bridge consists of girders. These parts are put together in factories before shipping to the work site and connected. This way of building makes work faster and cheaper.

• Length: 113.7 km
• Location: China
• Completed: 2010

9. Changhua-Kaohsiung Viaduct

The 157.3 km long bridge runs across the west of Taiwan. It carries the Taiwan high-speed rail between Changhua and Kaohsiung. It is one of the longest up-and-down bridges in the world, made with precast sections. The land has many earthquakes, so the bridge is set up so that the trains can stop on it safe during an earthquake. The bridge joins many cities and has very strong parts like piers and bearings that can withstand the ground shaking. This keeps the people safe. The whole build only took four years. The engineers used precast parts and new ways of building the whole thing. They built the bridge in parts and used the full span precast launch way and the balanced cantilever way, which made the build go faster.

• Length: 157.3 km
• Location: Taiwan
• Completed: 2007

10. Danyang Kunshan Grand Bridge

It is 165 km long. It links two big pest spots. The bridge is very strong. It is made to resist typhoon winds, and it is safe even if a tremor hits it, as big as 8. It could hold a navy ship that weighs 300,000 tons and hits the bridge straight on. The style it is built in makes use of many short spans and not just a few long ones. This is called viaduct and girder design. The bridge has 9500 big poles of cement and uses remolded cement, big pieces of metal, and deep sides that hold it up. One big piece of the bridge is 5.6 miles long and crosses Big Lake Yangcheng. Around 2000, big and small poles and ropes of metal helped to keep the bridge in place here. This amazing piece of work is a wonder of engineering. It gives you a neat show of use, size, and strength all in one. It looks great to boot.

• Length: 164.8 km
• Location: China
• Completed: 2010

Conclusion

To see the top 10 long bridges in the world is not just a big thing. It is a way for us to see how people join sights, make new things, and grow life. Some of the bridges are for fast trains. Others are for cars or for the busy town. All of them are very important because they help us go, do work, and see new sights. They want parts of towns, states, and even how nations help one another and work with each other. So, when you go over a long bridge, think about how it is. You are moving across a small part of a big network that keeps us joined and helps our world run.
