The Airport That Is Slowly Sinking Into the Ocean

#KansaiAirport #Megaprojects #Engineering The ocean floor was never designed to support a $20 billion airport. Japan built one anyway. Welcome to How Cities Function. Travel back to 1987 as we examine Kansai International Airport — one of the most ambitious engineering projects ever attempted. This is not simply an airport terminal. It is a massive artificial island built in Osaka Bay that has been slowly sinking since construction began. Today, millions of passengers pass through Kansai Airport every year. Yet beneath the runways, terminals, and taxiways, the ground continues to settle. What began as a solution to Japan's aviation problem became one of the most fascinating engineering experiments in modern history.
