How many years did it take to build a artificial island?

The time required to build an artificial island can vary significantly depending on its size, purpose, and construction methods. For instance, the Palm Jumeirah in Dubai took about six years to complete, from 2001 to 2007. Other projects, like the Kansai International Airport in Japan, took around 6 years as well. Overall, the construction of artificial islands can take anywhere from a few years to over a decade.
