Top 10 Most Impressive Civil Engineering Projects of All Time
Whether engineering is an art, a skill, or just a regular profession, history has shown that through engineering, mankind is continuously surpassing expectations and our natural limitations. There are many great civil engineering projects all over the world, but here we countdown the ones that transcend time and continue to impress and inspire new generations.
10. Qingdao Haiwan Bridge
Qingdao Haiwan Bridge,
also known as Jiaozuo Bay Bridge, is the world’s longest bridge over
water at 41.58 km (25.84 miles). It connects the city of Qingdao in
Eastern China with the Huangdao suburbs, across the water of Jiaozuo
Bay. The bridge was designed by the Shandong Gaosu Group, and it took
four years to build, with at least 10,000 workers employed for its
construction. Also, its construction costs equate to 900 million in
British pounds.
9. Burj Khalifa
As the tallest structure in the world, standing
at 829.8 meters, Burj Khalifa in Dubai was designed as the centrepiece
for a new development called Downtown Dubai. The building was named in
honour of the ruler of Dubai and president of the United States Arab
Emirates. It was designed by Skidmore, Owings and Merrill (SOM), and the
design is inspired by the patterns and structures in Islamic
architecture. The structure cost $1.5 billion to build. At the time of
its opening in 2010, it had the highest observational deck in the world.
The building has even featured in popular culture, as it can be seen in
2016 film, ‘Independence Day: Resurgence’. Burj Khalifa has broken
numerous other records, including building with most floors at 211 and
it has received immensely positive reception.
8. English Channel TunnelThe channel tunnel
links Folkestone, Kent in the UK with Coquilles, Pas-de-Calais in
northern France. Despite Japan’s Seikan tunnel being longer overall, the
channel tunnel has the longest undersea portion of any tunnel in the
world. It carries high-speed Eurostar passenger trains, as well as
Eurotunnel shuttle for road vehicles, which is the largest transport
system in the world. When it opened in 1994, the final cost came in at
an astounding £9 billion, making it the most expensive construction
project ever at the time.
7. Golden Gate Bridge
The Golden Gate Bridge is often considered one
of the most beautiful bridges in the world. This $27 million project is a
suspension bridge that spans the golden gate strait, connecting the
city of San Francisco to Marin County. It opened in 1937 and was until
1964, the longest suspension bridge in the world. The bridge is one of
the most recognised and influential symbols of the United States.
6. Hoover DamConstructed during the Great
Depression, the Hoover Dam is a concrete arch-gravity dam in the Black
Canyon of the Colorado River. The construction of the Hoover Dam claimed
hundreds of workers’ lives, and impounds Lake Mead, the largest
reservoir in the United States. The dam is named after President Herbert
Hoover, and it took five years to build and cost around $49 million.
5. Panama Canal
Panama Canal is a 48-mile waterway in Panama
that connects the Atlantic Ocean with the Pacific Ocean. The canal
consists of several artificial lakes and channels, and two locks at
either end. The canal cuts across the Isthmus of Panama and is crucial
for international maritime trade. Work on the canal began in 1881, and
it was finally opened in 1914, costing the Americans $375 million.
4. Brooklyn Bridge The Brooklyn Bridge is one
of the oldest bridges in the United States, and it’s both a suspension
and cable-stayed bridge. Completed in 1883, it connects the boroughs of
Manhattan and Brooklyn by spanning the East River. The bridge was
initially designed by German engineer, John August Roebling, but due to
his death, he was replaced by his son, Washington Roebling who took
charge of the project. It cost $15.5 million to build. Since it opened,
it has become a historic icon of New York City, and was designated a
historic landmark in 1964.
3. Aqueduct of Segovia
More precisely known as the aqueduct bridge,
this Roman aqueduct is one of the most significant and best-preserved
ancient monuments left on the Iberian Peninsula. It is located in Spain
and is the symbol of Segovia, and has been kept in excellent condition
over the centuries. It provided water to Segovia until the 19th century.

2. Great Wall of ChinaWith a history of more
than 2,000 years, many sections of the Great Wall of China are in ruins,
but it is still one of the greatest wonders of the world, and an
immensely popular tourist attraction. The Great Wall stretches from
Dandong in the east to Lop lake in the west. The entire wall with all
its different branches, measures out to be 13, 171 miles. It isn’t
possible to know exactly how much the wall would have cost to build, but
modern calculation say it would be somewhere between $13billion and $65
billion.
1. Great Pyramid of Giza
The Great Pyramid of Giza is the oldest of the
Seven Wonders of the Ancient World. It is the oldest and largest of the
three pyramids in the Giza pyramid complex, bordering El Giza, Egypt. It
is believed that the pyramid was built as a tomb for the fourth Dynasty
Egyptian pharaoh, Khufu and was constructed over a twenty-year period.
It is believed by many that Khufu’s vizier, Hemon, or Hemiunu, is the
architect who designed the pyramid. It remained the tallest man-made
structure in the world for over 3,800 years. Also, experts estimate that it would cost around $5 billion to build a replica today.
So, over the centuries, we have seen many great civil engineering projects that have become historic landmarks and icons. Engineering has created some of the biggest structures in the world, and are a showcase of our ability to construct a unique vision. Every engineer will have a different opinion on the most impressive creations, but these ten are widely considered the greatest. However, there are many other engineering creations that have impressed the world, such as the Millau viaduct, which is the tallest cable-stayed road bridge in the world. Also, as recently as 2015, the Shanghai Tower skyscraper in China, was completed and it’s now the second-tallest building in the world. The future is bright for engineering, as advanced technology will pave the way for even more stunning creations.
