The Most Expensive Construction Projects Ever

The Kansai International Airport cost an estimated $29 billion to make. It is located off of Japan, in the middle of Osaka Bay. It rests on a man-made island, which was constructed to resist the semi-frequent earthquakes and tidal waves of the region. Another reason for building it in the water was to avoid noise complaints.Kobe and Osaka were losing trade to Tokyo, so plans for the airport were introduced in the 1960’s. Metal SUPPORT columns and other structural pieces have had to be added to it over the years, in order to prevent it from sinking.
