1 – Building theWorld’s Longest Undersea Railway – The Channel Tunnel Story
Reveal the epic challenges faced by over 13,000 workers, from battling the elements to overcoming technological hurdles, culminating in the completion of a colossal collaboration connecting Britain and France.
The Channel Tunnel, or “Chunnel,” connects the United Kingdom and France under the English Channel and is a magnificent feat of engineering. This innovative project’s construction started in 1988 and ended in 1994. The English Channel Tunnel Connects United kingdom and France By Rail network. This Tunnel is the world longest under water tunnel. This video will explain how the world longest underwater tunnel was built
The Channel Tunnel or Euro Tunnel was an extremely complex engineering and construction undertaking. More than 13,000 people on both sides of the Channel worked on the project, making use of cutting-edge technology and methods.
To create the underwater tunnels, enormous tunnel boring machines (TBMs) were used. These TBMs might gnaw through the chalky subsoil beneath the ocean floor. The soil and rock were hauled away for reuse in landscaping and land restoration.
During construction, worker safety was of utmost importance due to the presence of hazardous geological features and the possibility of water infiltration. To protect the safety of its users, the English Channel tunnel was precisely planned with escape routes and high-tech ventilation systems.
The engineers had a difficult task ahead of them in joining the tunnel’s two ends. To get the two pieces of tunnel to line up perfectly, they used cutting-edge surveying and positioning technologies.
The train which travel between United Kingdom and France Through English Channel Tunnel is also called Euro Tunnel Train.
The Channel Tunnel or Euro Tunnel is a symbol of international cooperation and human inventiveness. It has opened up new opportunities for business, travel, and tourism between the United Kingdom and France. The Chunnel is a symbol of what can be achieved when imaginative ingenuity and tenacity are combined, and it continues to be one of the most recognizable engineering feats in the modern world

S1 billion Beipanjiang Bridgeworld’s highest bridge in China
This is a story of pushing beyond limits and embracing the unknown. China has constructed the world’s highest bridge, accomplishing it in a remarkable three years. The completion of this bridge not only showcases a significant breakthrough in science and technology but also presents a miracle where the impossible becomes possible.
China’s rapid economic development has brought numerous large-scale construction projects to the forefront, including the Sichuan-Tibet Railway and the Baihetan Hydropower Station. However, when it comes to advanced bridge engineering, Guizhou, China stands out. As the saying goes, eight out of the world’s top ten highest bridges are located in Guizhou. Among them, the most impressive is the “Beipanjiang Bridge,” renowned as the highest bridge globally, with a total height exceeding 565 meters. Some even compare driving on this bridge to flying an airplane.
The Beipanjiang Bridge is situated in western Guizhou, characterized by its karst landforms with steep gullies and clusters of karst caves. The bridge spans the Beipan River, which separates Yunnan and Guizhou provinces. Construction on the Beipanjiang Bridge began in 2013, undertaken jointly by China’s West China Design Institute and China Railway Construction Corporation, with a total investment of 1 billion yuan.
The suspension bridge stretches 1341.4 meters across the Beipanjiang Canyon, with a vertical height of 565 meters from the bridge deck to the valley bottom, equivalent to the height of a 200-story building. By the end of 2014, the main structure of the bridge was completed, and in June 2016, it was fully opened to traffic. This significantly reduced travel time between Liupanshui City and Xuanwei City from five hours to one hour. The astonishingly short construction period of only three years has earned it the reputation of a miracle in Chinese construction history. Surpassing the Haijijiao Canyon Bridge, the tallest bridge in foreign countries, the Beipanjiang Bridge aspires to become the highest bridge globally
, the construction of the world’s tallest bridge faced skepticism from some American experts. They believed that completing such a large-scale project in just three years was impossible. They also expressed doubts about the bridge’s durability, questioning its ability to withstand heavy traffic and natural disasters. Nevertheless, the bridge, costing over 1 billion yuan, defied expectations and became a reality within three years. Utilizing cutting-edge technologies and overcoming numerous challenges, Chinese scientists and construction workers accomplished what was initially deemed impossible.
Upon completion of the Beipanjiang Bridge, American experts were amazed and impressed. They praised the strength and expertise of Chinese engineers and construction workers, acknowledging China’s leadership in global construction technology and expressing the need to learn from them.

Information about the canal, from Wikipedia-
The Panama Canal (Spanish: Canal de Panamá) is an artificial 82 km (51 mi) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Straits .

OCTOBER 23, 2024
By Joshua Klemm, Co-Executive Director
As world leaders gather this week in Washington, DC for the World Bank’s Annual Meetings, over 100 civil society organizations are raising the alarm over the World Bank’s plans to lend billions of dollars for ill-conceived and destructive megadams around the world. A letter sent to the World Bank today notes these plans “will not bring reliable, environmentally sustainable, affordable, accessible electricity” and fail to consider lessons from the Bank’s past failures and ongoing challenges for dam-affected communities seeking redress.
The Bank’s imminent approval of the Rogun dam in Tajikistan would be among the more egregious projects in recent memory. The dam – slated to be the world’s tallest – would displace 60,000 people, irreparably harm the livelihoods of tens of thousands of more, and destroy vast stretches of riparian ecologies in violation of the Bank’s own environmental and social standards. With a conservative price tag of over $11 billion, Rogun would rank among the costliest dams ever built and by far the largest dam the Bank will have supported in decades. With project completion projected to take at least another 15 years, Rogun’s electricity will be significantly more expensive than readily available alternatives. In the short-term, there remain significant risks, cited by the IMF, that the costs of constructing Rogun could lead to an unsustainable debt burden while preventing needed public investments in other sectors, including health and education.
The proposed Upper Arun dam in Nepal and its associated cascade of dams have engendered serious concern over the expected physical, cultural and economic dislocation of Indigenous Peoples without their consent, as required by World Bank policy. At the same time, Nepal’s hydropower output has been and will continue to be curtailed by climate change, while the growing risk of glacial lake outburst floods in the Himalayas poses existential threats to millions downstream. In September last year, the brand new, $1 billion Chungthang dam on the Teesta River washed away in minutes, impacting tens of thousands.
The World Bank’s apparent interest in re-engaging on the ill-fated Inga project in the Democratic Republic of Congo (DRC) is even more inexplicable. Eight years on since it was forced to cancel its $73 million investment in what has been promoted as the world’s largest hydropower scheme, the Bank is trying once again to revive a project that has for decades seen a revolving cast of actors come and go, leaving a trail of broken promises. Congolese civil society and communities have long criticized the project for its expected impacts that would include the displacement of 30,000 people, many of whom were displaced and impoverished by dams previously built at the Inga site; the debt burden that generations of Congolese would be saddled with; and the massive opportunity cost of not exploring energy options better suited to addressing persistent energy poverty.
Unfortunately, none of this is new. The World Bank’s voracious appetite for dams and the resulting legacy of environmental and social impacts led to the creation of the World Commission on Dams (WCD) process, whose recommendations still serve as the standard for how to avoid the worst impacts of dams and whose lessons remain highly relevant today. The WCD process also precipitated a relative fallow period for the Bank in funding new dams, though the size and scale of projects currently under consideration suggests the Bank once again plans to take up the mantle as a prominent financier of megadams.
However, times have changed, and the conditions for developing new dams have worsened considerably in recent years. Large hydropower has rightly fallen out of favor around the world, experiencing several years of decline globally in the face of high costs, dwindling output, the declining costs of renewable alternatives, the steep environmental and social costs, and the climate crisis upending its rationale and purported benefits. The World Bank should learn from the hard-earned lessons of its past and invest in real renewable energy solutions rather than megadams.
