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.
Visualizing the Footprint of Highways in American Cities
Highways improved mobility for the average American, ingraining the automobile into the urban fabric of American cities, for better and worse.
Visualizing the Footprint of Highways in American Cities
Driving on the open road is a defining feature of the American experience, made possible by coast-to-coast highways. It defined a generation of life and ingrained the automobile into the urban fabric of American cities, for better and worse.
Today’s animations show how highways reshaped the downtown cores of six American cities and created new patterns of urban life. But first, some background information on the creation of the interstate system.
The Interstate Highway System
The U.S. Interstate System was created on June 29, 1956, when Dwight Eisenhower signed the Federal-Aid Highway Act. It would eventually run 46,876 miles, cost $521 billion and take 36 years to complete.
From San Diego to Bangor, the interstate highway system connected Americans and opened up the country to commerce and geographic mobility like never before, but for all its benefits, this new transportation network ripped through established patterns of urban and town life, creating a new era of urban development.
The Legacy of Highways: The Suburbs and Inner Cities
The vast geography of continental America helped to entrench personal mobility and freedom into American society. Highways and automobiles accelerated this lifestyle and even changed the shape of entire cities.
According to Prof. Nathaniel Baum-Snow of the University of Toronto, between 1950 and 1990, the population of central cities in the U.S. declined by 17% despite a population growth of 72% in larger metropolitan areas during the same period. Baum-Snow posits that, had the interstate highway system not been built, central cities’ populations would have increased 8%.
Firms followed the workers to the suburbs, but the highways system also created additional benefits for these firms. Cross-country road access freed manufacturing from ports and downtown rail hubs, while allowing economies to operate across larger distances, altering the dynamics of typical urban economies.
Faced with this new reality, inner cities struggled in years to come.
The introduction of highways created an increase in the supply of land for development through faster commutes to outlying areas. In 1950, half of all jobs were located in central cities. By 1990, less than one-third of urban jobs were located in the core of American cities.
“Not TV or illegal drugs but the automobile has been the chief destroyer of American communities.” Jane Jacobs, Author The Death and Life of Great American Cities
Benefits of new development accrued to the outer areas while the construction of the highways in inner cities displaced largely low-income communities, segregated neighborhoods, increased the amount of air and noise pollution, devalued surrounding properties, and removed access to jobs for those without a car, further concentrating poverty.
Before and After: Six American Cities
A bird’s eye view of six American cities reveals what was and what is now. By overlaying existing highways over the neighborhoods they replaced, it becomes clear how much interstate construction drastically altered America’s urban landscape.
Public opposition to the construction of I-980 was so strong that developers abandoned the project in 1971, only to complete it over a decade later.
The I-95 carved through Miami’s largely black Overtown neighborhood. The construction of a single highway cloverleaf resulted in 20 square blocks being demolished, displacing over 10,000 people in that community.
The I-95 comprised unconnected segments between 1957 and 1965 through the densest urban areas in a deliberate effort to prevent premature suburbanization and to revitalize the downtown core.
The I-71 cuts downtown Cincinnati off from its waterfront and a massive freeway interchange forced the destruction of dozens of blocks west of downtown.
Freeway construction transformed Detroit between 1951 and 2010. Previously, its downtown had been surrounded by a high-density street grid. Today, it’s totally encircled by freeways.
Rochester is one of many cities opting to undertake freeway removal projects.
As the dotted line above shows, the “moat” surrounding downtown is slowly being removed. The city used reclaimed land from the Inner Loop freeway to construct three mixed-use developments that include below-market-rate units.
The Future of Urban Living: Do Highways Matter?
A new era of living is reconsidering the impacts of these highways on urban centers. As property values rise and existing housing stock is pressured, there are growing concerns over the environmental impacts of suburban life. As a result, urban planners and residents are looking to revitalize city cores and re-purpose land occupied by burdensome slabs of highway concrete.
Since 1987, there have been more than 20 urban highway segments removed from downtown cores, neighborhoods and waterfronts, mostly in North America. The pace of removals has picked up significantly and an additional 10 highways are now planned for removal in the United States.
During the COVID-19 pandemic, American cities have seen their traffic plummet. Rush-hour trips into cities are taking nearly half the time while some are not even commuting at all.
While this situation is likely temporary, it is offering a moment for reflection of how cities operate and whether the car should be at the center of urban planning.

In just a few decades, it’s possible that some of today’s most recognized companies may no longer be household names.
Corporate longevity, or the average lifespan of a company, has been shrinking dramatically.
In the 1960s, a typical S&P 500 company was projected to last for more than 60 years. However, with the rapidly transforming business landscape today, it’s down to just 18 years.
The Companies With the Strongest Staying Power
Even with companies skewing younger, there are always exceptions to the rule.
Luckily, many companies around the world have stood the test of time, and today’s detailed map from Business Financing highlights the oldest company in existence in each country.
For centuries, here are the world’s oldest corporations which have made their mark:
|578||Kongō Gumi Co., Ltd.||Japan||Construction|
|803||St. Peter Stifts Kulinarium||Austria||Service Industry (Restaurant)|
|862||Staffelter Hof||Germany||Distillers, Vintners, & Breweries (Winery)|
|864||Monnaie de Paris||France||Manufacturing & Production (Mint)|
|886||The Royal Mint||England||Manufacturing & Production (Mint)|
|900||Sean’s Bar||Ireland||Service Industry (Pub)|
|1040||Pontificia Fonderia Marinelli||Italy||Manufacturing & Production (Bell foundry)|
|1074||Affligem Brewery||Belgium||Distillers, Vintners, & Breweries|
|1135||Munke Mølle||Denmark||Manufacturing & Production (Flour Mill)|
|1153||Ma Yu Ching’s Bucket Chicken House||China||Service Industry (Restaurant)|
Whether they were born out of necessity to support a rapidly growing population—requiring new infrastructure and more money circulation—or simply to satisfy peoples’ thirst for alcohol or hunger for fried chicken, these companies continue to play a lasting role.
The Oldest Company in Every Country, by Region
Let’s dive into the regional maps, which paint a different picture for each continent.
In the following maps, countries are color-coded based on the major industry that the oldest company falls under:
- Primary: Natural resources
- Secondary: Manufacturing and processing
- Tertiary: Services and distribution
- Quaternary: Knowledge and information
Notes on Methodology:
This research considers both state-run and independent businesses in their definitions. For countries where data was hard to pin down, they have been grayed out.
As well, since many countries have a relatively new inception, present-day names and borders have been used. The map does not factor in older companies that are no longer in operation, or if it was unclear whether they were still open.

Mexico’s La Casa de Moneda de México (founded 1534) is the oldest company across North America, and the first mint of America. Owned by the Spanish conquistador Hernán Cortés, it was where the famous ‘pieces of eight’, or Spanish dollars were created.
In the U.S., the Shirley Plantation in Virginia is an ongoing reminder of the history of slavery. First founded in 1613, business actually began in 1638—and as many as 90 slaves were under indentured labor on the estate growing tobacco.
Further north, Canada’s Hudson’s Bay (founded 1670) was at the helm of the fur trade between European settlers and First Nations tribes—the two parties agreed on beaver pelts as a common, valuable trade standard.
Three of the five oldest companies in South America are mints—specifically in Brazil, Colombia, and Peru.
The oldest of these mints, Casa Nacional de Moneda in Peru, was built on order from Spain and established in 1565. After the great influx of newly-mined silver from America to Europe, the Spanish crown outlined to King Felipe II that building a mint would give the colony economic benefits and more control.
In total, 15 of Europe’s oldest companies are related to the food and beverage industries, from distilleries, vintners (winemaking), and breweries alongside restaurants and pubs. Austria’s St. Peter Stifts Kulinarium (founded in 803) is Europe’s oldest restaurant, located inside the St. Peter’s Abbey monastery.
Although Germany is famously known for its beer culture, its oldest company is in fact the Staffelter Hof Winery (founded in 862). Today, Germany is still a top wine country, with the industry generating up to $17 billion in revenue per year.
Asia has six oldest companies in the banking and finance category, as well as another six in the aviation and transport sector. The continent is also home to two of the world’s oldest companies, located in Japan and China.
The Japanese temple and shrine construction company, Kongō Gumi Co., Ltd. (founded in 578) has weathered a few storms over the millennia, from nuclear bombs to financial crises. In 2006, it was bought by the construction conglomerate, Takamatsu Construction Group Co., and continues to operate today.
In neighboring China, Ma Yu Ching’s Bucket Chicken House has endured dynasties of change as well. The company’s simple premise has come a long way, and it was named a cultural heritage in the country’s Henan Province.
Africa’s oldest companies are another vestige of the colonial legacy, with 11 transport companies—airlines, ports and shipping, and railways—and 9 postal services.
In fact, Cape Verde’s Correios de Cabo Verde (postal service, founded in 1849) and the DRC’s Société nationale des Chemins de fer du Congo (national railway company, founded in 1889) still go by their Portuguese and French names respectively.
Banking is another one of the oldest industries, with 17 companies across Africa. Zimbabwe’s Standard Chartered branch has been around since 1892, a subsidiary of its London-based parent company.
Australia officially became a country on January 1st, 1901—but its oldest company, the Australia Post (founded in 1809) precedes this by almost a century.
Interestingly, just one more old company could be located for this region, which is the Bank of New Zealand—one of the country’s Big Four banks.
All in all, these oldest companies paint a historical picture of the major industries which have shaped entire regions.
