Which is the longest man made object?

Answer 1

== == == The Great Wall of China is the longest man-made object on earth, which spans almost the entire length of northern China. In order to make this wall complete, thousands of Chinese were put to work. Segments of already standing walls had been connected and extended. The US Interstate Highway system is a mite longer, I'd say.

Answer 2

The Great Wall of China is generally considered the largest man-made structure, at least in terms of length and volume. The tallest man-made structure is currently the Burj Khalifa skyscraper, which is located in Dubai, United Arab Emirates.
