The 10 Most Impressive Civil Engineering Projects of All Time
The 10 Most Impressive Civil Engineering Projects of All Time
With every day that passes, thousands of new civil engineering projects are completed around the globe. They might be as simple as building the foundation for a house or as complex as designing a suspension bridge that spans an entire river.
Once in a while, however, a very special type of civil engineering marvel gets finished that is earmarked to forever exist in a league of its own.
Civil Engineering Feats
Today’s infographic comes to us from Norwich University, and it 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.
Mapped: European Colonial Shipping Lanes (1700‒1850)
This map plots the colonial shipping lanes used by the British, the French, the Spanish, and the Dutch in the 18th and 19th centuries.
European Colonial Shipping Lanes (1700‒1850)
Every year, thousands of ships ferry passengers and transport goods across the world’s oceans and seas.
200 years ago, the ships navigating these waters looked very different. Explorers and traders sailed from coast to coast to expand colonial empires, find personal riches, or both.
Before modern technology simplified bookkeeping, many ships kept detailed logbooks to navigate, tracking the winds, waves, and any remarkable weather. Recently, these handwritten logbooks were fully digitized into the CLIWOC database as part of a UN-funded project by the University of Madrid.
In this graphic, Adam Symington uses this database to visualize the British, French, Spanish, and Dutch shipping routes between 1700 and 1850.
Colonial Shipping Lanes
In the 18th and 19th centuries, the British, French, Spanish, and Dutch empires dominated global trade through their colonial shipping lanes.
All four nations sailed across the Atlantic Ocean with some frequency over that timeframe, but these fleets were also very active in the Pacific and Indian Oceans as well.
The table below reflects the record of days spent by digitized logbooks from each nation.
|Country||N. Atlantic||S. Atlantic||Indian Ocean||Pacific||All Oceans|
Does this mean that the Netherlands had the widest colonial reach at the time? Not at all, as researchers noted that there were thousands of logbooks from each country that weren’t able to be digitized, and thousands more that were lost to time. The days simply reflect the amount of data that was available to examine from each country.
But they can still give us an accurate look at critical shipping routes between European countries, their trade partners, and their colonies and territories.
Let’s now take a closer look at the colonial powers and their preferred routes.
The British shipping map shows a steady presence across the Atlantic and the Indian Ocean. They utilized many of Europe’s ports for ease of trade, with strong pre-independence connections to the U.S., Canada, and India.
One of the most frequented shipping routes on the map seen is a triangular trade route that enabled the trans-Atlantic slave trade. This route facilitated the transportation of slaves from Africa to the Americas, raw materials such as sugar, tobacco, and cotton from the American colonies to Europe, and arms, textiles, and wine from Europe to the colonies.
During this period, Spanish maritime trade with its colonies was an essential economic component of the Kingdom of Spain (as with other colonial empires).
We can see the largest concentration of Spanish ships around Central and South America leading up to the Spanish American wars of independence, as those colonies were especially important suppliers of raw materials such as gold, silver, sugar, tobacco, and cotton. There are some lanes visible to Pacific colonies like the Philippines.
Of the four empires, France’s maritime logbooks were the most sparse. The records that were digitized show frequent travel and trade across the North Atlantic Ocean to Canada and the Caribbean.
The French empire at the time included colonies in the Caribbean, Indian Ocean, and West Africa. Their trade routes were used to transport goods like sugar, coffee, rum, and spices, while also relying on the slave trade to maintain plantation economies. The French colony of Saint-Domingue (now Haiti) was one of the world’s wealthiest colonies in the late 18th century.
Dutch shipping routes from the time had the most detail and breadth of any country, reflective of the Dutch East India Trading Company’s position as the world’s dominant company and trade force.
These include massive traffic to the Dutch East Indies (now Indonesia), Cape Colony (now South Africa), and the Guianas in South America.
Interestingly, researchers from Leiden University found that the Dutch empire was a “string of pearls” consisting mostly of strategic trading hubs stretched along the edges of the continents and focused on maritime power.
