In 1994, the American Society of Civil Engineers compiled a list of the Seven Wonders of the Modern World. This was done to pay tribute to the 20th century's greatest civil engineering achievements.
7. Golden Gate Bridge -
The Golden Gate Bridge is a suspension bridge spanning the 1.6 km wide, 4.8 km long Golden Gate Strait between the Pacific Ocean and San Francisco Bay. The Bridge links San Francisco in California to the Marin County of the country. A leading travel guide has described the Golden Gate Bridge as the most photographed bridge in the world, and it also enjoys being one of the Seven Wonders of the Modern World.
6. Empire State Building -
Manhattan in New York City hosts one of the Seven Wonders of the Modern World, the 102-story tall Empire State Building. The building rises to a height of 1,454 feet. For nearly 40 years, the Empire State Building enjoyed the title of being the world’s tallest building. The building serves as a cultural icon of America. The Empire State Building has been featured in several films, television shows, and literature. Nearly 110 million people have visited this New York City attraction. The 86th-floor observation deck of the Empire State Building offers an impressive view of the entire city.
5. CN Tower -
The 553.33 m-high CN Tower is another one of the modern marvels of our world and is thus credited as one of the Seven Wonders of the Modern World. The structure is located in downtown Ontario and was completed in 1976. It held the title of the world's tallest free-standing structure for 34 years since its completion. Presently, the CN Tower is the Western Hemisphere’s tallest free-standing structure and the iconic symbol of Toronto’s skyline and Canada. More than two million visitors visit the CN Tower every year.
4. Channel Tunnel -
The Channel Tunnel is a tunnel that runs beneath the English Channel at the Strait of Dover from Folkestone, Kent, the UK to Coquelles, Pas-de-Calais, France. The channel is 50.5 km long with a 37.9 km long undersea portion. The channel is 250 ft deep at its lowest point. Trains are allowed to run through the tunnel at a maximum speed of 160 km/hr. The tunnel provides passage to high-speed Eurostar passenger trains, Eurotunnel Shuttle, and international freight trains.
The construction of the Channel Tunnel was initiated in 1988 by Eurotunnel, and it was opened in 1994. Since its construction, the Channel Tunnel has faced several problems like cold weather and fires. Also, illegal immigrants have in the past tried to enter the UK via the tunnel. Despite these issues, the Channel Tunnel is regarded as one of the Seven Wonders of the Modern World.
3. Itaipu Dam -
The Itaipu Dam is a major hydroelectric project that is located on the Paraná River between Paraguay and Brazil. The project is a binational undertaking that was completed in 1984. The Itaipu Dam has an installed generation capacity of 14 GW. 20 generator units are part of the project of which ten generate at 60 Hz for Brazil, and the other ten generate at 50 Hz for Paraguay.
2. Delta Works/ Zuiderzee Works -
The Delta Works/ Zuiderzee Works is one of the largest hydraulic engineering projects undertaken by the Netherlands in the 20th century. The project involved the construction of a massive system of man-made dams, dikes, water drainage systems, land reclamation works, etc. The Zuiderzee Works involved the damming of a stretch of water in an inlet of the North Sea and reclamation of land in the newly created dam. It aims to control flood and facilitate agriculture.
1. Panama Canal -
The Panama Canal, an artificial 77 km waterway in Panama is one of the Seven Wonders of the Modern World. It serves the vital function of connecting the Pacific Ocean to the Atlantic Ocean across the Isthmus of Panama, facilitating international maritime trade. Regarded as one of the biggest and most difficult engineering projects of the modern times, the Panama Canal has greatly reduced the time for ships to move between the oceans. The ships can now avoid the hazard-filled and time-taking route around Cape Horn, South America’s southernmost tip.
