The Eurotunnel Is One of the Seven Wonders of the Modern World. With More Than 50 Km in Length and a Construction Cost of Nearly 120 Billion Reais

The Eurotunnel is one of the seven wonders of the modern world, according to the American Society of Civil Engineers. With more than 50 km in length and a cost of nearly 120 billion reais, this construction is one of the most notable and useful projects in recent human engineering.

Created to simplify transportation and benefit the economy of two of the world’s major economic powers, England and France, the Eurotunnel will celebrate 30 years of operations in 2024. In this article, you will learn more about this masterpiece and all the benefits it has provided to millions of Europeans.

The idea of creating a fixed link between Great Britain and France dates back to the early 19th century, but it was only in 1986 that the project gained significant momentum with the signing of the Anglo-French Treaty on the Channel Tunnel. This treaty established the foundations for the construction and operation of the Eurotunnel by private companies, culminating in the formation of the joint venture TransManche Link, composed of British and French builders.

The Construction of the Eurotunnel: A Brief History

Inaugurated in 1994, the Eurotunnel connects the town of Folkestone, in Kent County, England, to the commune of Coquelles, in the Pas-de-Calais department, France. This underwater tunnel runs beneath the English Channel, a stretch of the Atlantic Ocean that separates southern England from northern France, serving as the only fixed link between the island of Great Britain and the European continent.

With a length of 50.45 km, the Eurotunnel is the third longest operational railway tunnel in the world. The underwater section of the tunnel, measuring 37.9 km, is the largest in this regard. The Anglo-French construction consists of two main railway tunnels with a diameter of 7.6 m, separated by a service tunnel, all connected by cross passages and piston relief ducts.

Benefits and Services Offered by the Eurotunnel

The Eurotunnel offers various services, including Eurostar, a high-speed train that connects London to Paris and Brussels; Le Shuttle, which transports vehicles through the tunnel; truck transport by train, allowing drivers to travel separately; and Europorte, which is the conventional freight transport service. These services significantly contribute to the integration and economic development of the regions served by the Eurotunnel.

Challenges and Impacts of the Eurotunnel

During its construction, the Eurotunnel faced various technical challenges, including the geological variation of the region and the need to excavate through varying geological conditions. Additionally, the tunnel also faced challenges related to illegal immigration, being seen as an attractive route for people seeking to enter the United Kingdom clandestinely.

The Eurotunnel is truly a masterpiece of global engineering, representing a successful union between England and France for mutual benefit. Over the years, the Eurotunnel has provided an efficient link between the United Kingdom and Continental Europe, generating better accessibility and strengthening the local economy. As one of the greatest achievements of modern engineering, the Eurotunnel will continue to be an important part of Europe’s history and infrastructure.

Challenges and Impacts of the Eurotunnel

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.

An astronaut spent 340 days in space while his twin brother stayed on Earth, and NASA found a “rejuvenating” effect, genes, microbiome, cognition, and immune system that revealed the biological cost of living outside the planet.

After 14 years of construction and a diplomatic crisis that nearly led to a military confrontation over control of the Nile, Ethiopia inaugurated the largest hydroelectric power plant in Africa — the dam is 170 meters high, holds 74 billion cubic meters of water, and generates 5,150 megawatts.

Maximum alert for the South: an extratropical cyclone puts 24 cities in Rio Grande do Sul in danger this Sunday, with gusts of up to 60 km/h, intense rain, and risk of flooding, fallen trees, and power outages.

On a scale few countries can imagine, China is preparing thousands of robots to take over the operation of its power grid, reduce human error, sustain the explosive advance of artificial intelligence, and transform energy into a smarter and more autonomous infrastructure.

The Brazilian state most vulnerable to natural disasters accounts for 41% of Civil Defense alerts, faces cyclones, floods, hail, and tornadoes, and lives under a climatic combination that seems like a perfect storm.

The coldest day of the year already has a date set, and the most intense polar air mass of 2026 will drop temperatures to 0°C in the South with a risk of frost between Monday and Tuesday, when thermometers reach historical lows for April.

Seen from high in the stratosphere, a Lego Star Devourers rose to 34,988 meters attached to a balloon, returned to Earth intact, and entered the Guinness World Records in a record that seems like science fiction.
