Today’s infographic counts down the 10 most impressive civil engineering projects ever completed by humanity.
These unique and extremely bold endeavors tend to exceed all normal standards of size, complexity, and manpower required. They transcend time and bestow wonder upon new generations, showing that incredible feats are possible with the right team, ideas, and expertise at hand.
Some of these projects were also included on the 1994 list of the Seven Wonders of the Modern World, put together by the American Society of Civil Engineers.
Meanwhile, the Great Pyramid is the only entry from the Seven Wonders of the Ancient World list.
Counting Down the Top 10
Here are the projects, going from #10 all the way to #1:
10. Qingdao Haiwan Bridge
This 26.4 mile (42.5 km) bridge was completed in 2011 in China, using 450,000 tons of steel and 3 million cubic yards of concrete.
9. Burj Khalifa
The world’s tallest skyscraper is one of many fascinating projects in Dubai. It reaches 2,717 ft (828 m) in height, almost a full 1,000 ft higher than One World Trade Center in New York.
8. English Channel Tunnel
This 31 mile (50 km) long tunnel is also up to 250 ft (76 m) deep, connecting England and France.
7. Golden Gate Bridge
This historic wonder connects San Francisco to the rest of the bay, and needed an incredible 600,000 rivets in its construction.
6. Hoover Dam
This dam formed the largest man-made lake in the Western Hemisphere, and it generates 4 billion kWh of energy per year.
5. Panama Canal
This 47 mile (77 km) long man-made canal was designed to connect the Atlantic and Pacific oceans to provide trade ships with passage between North and South America. It needed more than 60 million pounds of dynamite to dig.
4. Brooklyn Bridge
The first suspension bridge to use steel in its cables was also the longest in the world at the time of its construction.
3. Aqueduct of Segovia
This amazing aqueduct in Spain was made without the use of mortar, and is so well-preserved that it is still in use today.
2. Great Wall of China
What many people do not know about this enormous 5,500 mile (8,850 km) long wall is that the mortar connecting stones was made from rice flour.
1. Great Pyramid of Giza
This incredible creation is made of 2.3 million stone blocks, which required the constant labor of 30,000 people to build. It was the tallest man-made structure for more than 3,800 years.
A Final Note
The list represents the ranking as done by Norwich University’s civil engineering department, and surely there are other incredible feats that are missed by this ranking. Those would include projects like the Three Gorges Dam in China, the CN Tower, and many other worthy accomplishments.
