The Most Expensive Construction Projects Known to Mankind
1. Airport in Al Maktoum
Location: UAE's Dubai Total Expense: $82 billion * Completed Year: 2010 The nearly eight thousand weekly flights that are operated by about 140 airlines that depart from the Al Maktoum Airport each week reach more than 270 destinations. The over fifteen thousand-foot runway was constructed in just six hundred days, and its safety testing took nearly two-thirds of a year longer.

2. The pipeline system in Alaska
Place: Alaska Total Expense: $8 Billion* Completed Year: 1977 The 1973 oil crisis gave rise to a significant spike in oil prices, which gave rise to the Trans-Alaska Pipeline System, a "pipe" dream. After a little over three years, work on the eight hundred miles of the Trans-Alaska Pipeline System was finished in the first half of 1977, and the pipeline was operating at full capacity by the end of the same year. More than seventeen billion barrels of oil are said to have been delivered through the pipeline's eleven pump stations by 2014.
