One of the benefits of the way that we live in large societies is that we’re able to pool our resources to embark on huge megaprojects that, in theory, are intended to benefit everyone. Whether this be for scientific pursuits, infrastructure, or providing valuable resources to where they’re needed… complicated machinery, difficult terrain, or vast and ambitious designs can soon see the costs skyrocket. It’s time to travel the world, and beyond, to see just what’s possible when there’s enough commitment to an idea, as we take a look at the 15 most expensive construction projects ever built.

  1. This was a very informative video. I had never heard of a handful of these projects.

  2. fun fact: I-5 is the only continuous interstate highway that touches both the Mexican and the Canadian borders. second fact if you didnt know, even numbered interstates/highways travel east/west and odd numbered travels north/south

  3. Interesting projects, but I question the one about the interstate system in the US: The Chinese highways cover double the distance by now and has been built in much shorter time, so it makes more sense to classify them as one project,. It may have been cheaper of course, due to chinese wages.
    As for clean energy, another interesting project is the Wendelstein 7x stellarator.

  4. Man, the belt and road project seemed like such a cool idea at first until the political part is mentioned lol

  5. #top15 , china's Belt and Road Project is Dead coz china has lost more then $ 9.2 Trillion , consider china as Bankrupt now and that's the reason why International Businesses , companies , factories and industries are leavin china…

  6. Does anyone have a decent estimate of how much it cost to build the Palm Islands in Dubai? (including The World Islands and the marina)

  7. Russia is doing free teardown for another mega redevelopment project. It will be gentrified and too expensive for the ordinary people Ukraine is asking to stay and fight the demolition country .

  8. In 10 years countries who allowed themselves to be indebted for belt and road will look exactly like that paper. 8.08

  9. Can I know about Forest City? The Big Tower is it an Exam Place(a Human Ranking Place[Strength of Mind that is Equal to a Level of Education]) by Playing Games?
    What is the Plan of the Place? If a Kind of Formality to Crush Does it Exist(A Pretence or Pose) in an Approach to Someone(maybe Targeted) to Create Awkwardness Until Clumsiness that Can Be Injured(About Memory of Life – Reaction, Mouth Sayings or Writings, Actions, About Perfection Belief in "A Lovely Family")? If a Calculation of Reaction to Position(Heart of Person in the Care of Unique Belief?) Someone? Including A Kind Like Suicide-Move In Mass(Example: All Cars Accident At Once but Never Die On Purpose with Airbag to Attack a Company of Car) Type of Actions?

  10. 9. i understand the dangers of the old city that there trying to fix. but "bulldozing" the old beautiful and historic structures and replacing them with ugly modern cookie cutter buildings is not the answer.

  11. The euro tunnel is at the top of my road. Used to work there. Would always tell people to sit or try and park next to window so the can see all the fish as the trians going. 😇

  12. I believe you missed India. one of the projects here is delhi mumbai industrial corridor which costs around 100Billion. This is one of the few project costs more than 50B here.
