The American Society of Civil Engineers created a list of Seven Wonders of the Modern World in 1994, including a tunnel, tower, skyscraper, bridge, dam, dike, and canal. These marvels are diverse and chosen based on function, design, and engineering achievement. Interesting facts include five wonders’ connection to bodies of water and Itaipu Dam being the largest hydroelectric power station in the world. The society continues to ask for nominations for worthy contenders.
As a counterpoint to the Seven Wonders of the Ancient World — feats of architecture and sculpture from ancient times — the American Society of Civil Engineers created a list of Seven Wonders of the Modern World in 1994. Each structure was chosen based on its function, design, , and the engineering achievement at the time of its construction. In some ways, these marvels are more diverse, each representing a distinct type of structure: a tunnel, a tower, a skyscraper, a bridge, a dam, a dam, and a canal.

Interesting facts about the seven wonders of the modern world:
Five have a close connection to bodies of water, while only two of the wonders of the ancient world – the Pharos and the Colossus – do. Various wonders of the modern world pass through water, under water and above water. While two of the ancient wonders were in Africa, two in Asia Minor, two in Europe and one in the Middle East; modern wonders include three in North America, two in Western Europe, and one in Central and South America. Itaipu Dam is the largest hydroelectric power station in the world. The Golden Gate Bridge was the longest suspension bridge in the world when it was built. The cables used to support the bridge are long enough to go around the globe three times. While there are many stories about how often the bridge is painted, since 1995 it has only required touch-up work on areas prone to environmental corrosion. The Channel Tunnel is nicknamed the Chunnel and includes over 300 miles (482.8 km) of cold water pipes, designed to compensate for the heat caused by train speed in the closed tunnel. Toronto’s CN Tower is the tallest free-standing structure on the planet and is actually three times taller than Seattle’s Space Needle. The Empire State Building was the tallest building in the world from 1931 to 1972, when the first World Trade Center tower was completed. While not known for it, one of the most impressive things about the Empire State Building is that it took just 13 months to complete, with no overtime.
The American Society of Civil Engineers has asked people from around the world to submit nominations for worthy contenders for the Seven Wonders of the Modern World./li
