Countless times, many people wonder that among popular bridges, which is the longest bridge in the world? Which is the highest or tallest bridge in the world? And many other similar popular questions. This is why our team at finds this type of write-up really fascinating because every single detail is just exciting and breathtaking.

It is often said that as humans, “whatever we put our mind to, we can achieve”. Well, this expression might be the perfect explanation and the reason why some of the amazing bridges around the world could be built. Bridge construction has never been recorded to be an easy task anywhere around the world.


The Iron Bridge which was opened in 1781 initially seemed like an unrealistic and impossible idea

As a matter of fact, most bridge construction workers are fond of remarking that initially, a bridge would first seem almost impossible and difficult to build. But with hard work, courage, persistence coupled with quality materials and tools, any bridge can be built, like the very first iron bridge as in the picture above. And today, we gather here the most amazing works of humans around the world, let's dive in!

1. The world's longest bridge

Even though there are countless numbers of high, big and long bridges all over the world, China, however, has been one nation that blows everyone’s mind with their amazing and notable bridges. Don’t be surprised that they have lots of bridges with high reputation and popularity all over the world. Some of their bridges even hold quite a number of the Guinness World Records. So, as you would guess, the world’s longest bridge in the world is in China. It is the Danyang–Kunshan Grand Bridge. This same bridge also happens to be the longest railway bridge in the world. Read the full details of this bridge below:

1.1. Longest railway bridge in the world: Danyang-Kunshan grand bridge

Like we just mentioned above, the bridge that stands to be the longest railway bridge in the world is the Danyang–Kunshan Grand Bridge. It really gets confusing when you are searching up the titles given to these bridges over the Internet and in books, because records change with time and different characteristics and measurement standards are considered and used when given choosing these world records. As a matter of fact, most of the bridges holding one title or the other are always closely similar in measurements to their rivals/ competing runner-ups.


Danyang–Kunshan Grand Bridge is the longest bridge in the world

The world’s longest bridge – Danyang - Kunshan Grand Bridge was opened around June in the year 2011 with a span of 165 km (102.4 miles) long viaduct and on the High-Speed railway of Beijing-Shanghai. It is located between Shanghai & Nanjing in the Jiangsu province on the rail lines. This bridge falls in the Delta of the Yangtze River at about roughly 8-80 Km parallel to the river. It spans from west to the east, passing through the edges (northern) of the population centers which begins in Danyang, cuts through Suzhou, Wuxi, Changzhou, and ends in Kunshan.

 It took China just 4 years to construct the Danyang - Kunshan Grand Bridge with about 10,000 employed workers and at a total cost of around ₦3.1 billion ($8.5million).


It has been discovered that often times, people confuse the Qingdao Haiwan Bridge or Jiaozhou Bay Bridge as the world’s longest bridge. This is not true, the Jiaozhou Bay Bridge is of course in China but it’s just one of the longest bridges in the world. The Danyang - Kunshan Grand Bridge is the only record holder for the “World’s longest bridge” as of date.

Also, as at the time of writing this article, the latest record holder among China’s most popular breathtaking bridges just bagged the world record for “Longest sea bridge in the world”. Read about this bridge below:

1.2. Longest sea bridge in the world: Hong Kong-Zhuhai bridge

It is now official as of October 2018, that the Hong Kong-Zhuhai bridge is currently the longest sea bridge in the world. It was opened by President Xi Jinping (Chinese president after about 10 years since its construction began). This bridge spans 34 miles (55 km) and it connects the Chinese mainland city (Zhuhai) to Hong Kong and to Macao. It really extended over all its initial target opening dates and budgets many times.

First, it was supposed to have been opened in 2016 but extended till 2018. Then, its final construction cost rounded up to about ₦7.3 trillion ($20 billion) which was way over the initial undisclosed budget. 

World's longest sea bridge! Hong Kong-Zhuhai-Macao Bridge to boost logistics

It is rumored that some of the locals tagged the Hong Kong-Zhuhai bridge as “The bridge of death”. This is due to the fact that a total of at least 10 workers lost their lives during the construction of the bridge while a few other workers incurred several injuries. Well, we find it worth mentioning that this world’s longest sea bridge has some fascinating features. One of the features is that it is built in such a way that it can withstand typhoons and earthquakes with strong steel of about 400,000 tonnes. This amount of steel is enough to build sixty more Eiffel Towers practically.

1.3. Longest river bridge in the world

The longest river bridge in the world is the “Lake Pontchartrain Causeway”. Yes, we could already guess that at this is point people will find our information confusing. You might think that we have gotten things mixed up because we mentioned earlier and discussed “the longest bridge in the world”. Of course, we did. But, that was the Hong Kong-Zhuhai bridge which we clearly stated that it holds the world record for the Longest sea bridge in the world, right?

Well, the difference between these two is just in the title. The Hong Kong-Zhuhai bridge is the world’s longest sea bridge while the Lake Pontchartrain Causeway is the world’s longest river bridge or the world’s longest continuous bridge over water. This “continuous” category had to be created by the Guinness world record as the Lake Pontchartrain Causeway remains the bridge in the world with the highest number of spans over a straight length of water.

The longest bridge in the world over water (continuous)

So, officially the world’s longest continuous bridge over water is the “Lake Pontchartrain Causeway”. It can be found southern Louisiana in the United States of America.


The Lake Pontchartrain Causeway hold the title for the world’s longest continuous bridge over water

It is actually 2 parallel bridges laid closely side-by-side. The longer one among the two bridges measures 38km (23.83miles) in length and both bridges are held firm by huge 9,500 concrete pilings altogether.

2. Extra nuggets: World’s highest bridge

We mentioned earlier in the introduction of this article that China holds many world records when it comes to bridges and that is so true. The world’s highest bridge also happens to be in China. Yes, they unveiled this bridge sometimes in the year 2016 and it is indeed a marvel as it stands 1,854ft tall, connecting two known mountainous regions in China. This bridge is officially called the “Duge Beipanjiang Bridge” and it links the Guizhou province with Yunnan province in China.


The world’s highest bridge “Duge Beipanjiang Bridge” build cost is approximate ₦52.5 billion

According to "The Guardian UK", this bridge shortens the familiar 5 hours Liupanshui - Xuianwei travel time to just 2 hours. The bridge’s construction which had commenced since 2013 ended in 2016. Launched in the same year, the Duge Beipanjiang Bridge is reported to cost about ₦52.5 billion ($144 million) in total to be built. China also happens to home the 2nd highest bridge in the world (the Sidu River bridge) as well as the 3rd world’s highest bridge (the Puli bridge) together.

There is a lot of controversies when comparing the two titles; “World’s highest bridge” and “World’s tallest bridge”. This is because the world’s tallest bridge is currently “the Millau Viaduct bridge” in France and it stands 1,125ft (343m) tall in height. Its construction cost approximated to about ₦164.9 billion. Even though the Millau Viaduct bridge is 8,070ft (2,460m) long, it is really just a mere 270m above the ground. This makes it not the highest bridge in the world as the Duge Beipanjiang Bridge is 565m above valley level.

If you are a bridge expert, you will understand the nitty-gritty behind this comparison and records. But, if you are curious and confused about these records, you can research into how bridges height is measured and determined for better understanding 😊.

3. Conclusion

Now you know which one are the longest bridge in the world and the highest bridge in the world right? When planning your next international vacation, you might want to include in your to-do list “enjoy a ride over world’s longest bridge”. Just imagine how you would feel when driving or walking over any of these bridges 😊.
