This famous canal was one of the most difficult feats of engineering in the world. It’s just over 50 miles in length and connects the Atlantic Ocean to the Pacific Oceans. This enables ships to pass from ocean to ocean without having to travel around Cape Horn. The canal can knock about 8,000 miles off of a single journey, such as San Francisco to New York.

The Skywalk is located on the rim of a side canyon which sits about 4,000 feet over top of the mighty Colorado River. The skywalk is very sturdy and can support over 71,000 pounds of weight and can handle 100 mile-per-hour winds.

This dam is known as the world’s biggest hydroelectric power station. It has a reservoir that’s 375 miles in length inside of a 7,661-foot concrete bulk. It’s a controversial dam because the sheer size of it has already displaced hundreds of thousands of people and has submerged dozens of cultural sites in the local Three Gorges region. It took seven years to build the dam.
