Top 10 most expensive construction projects in the world
Coming in at $22.4 billion, the Channel Tunnel stretches 31.4 miles connecting Britain with France. Buried beneath the English Channel, it is the favourite means of people to cross the watery divide between the UK and mainland Europe.
 9. The Big Dig
The whole project was concluded on the last day of 2007, ten years behind schedule and costing millions of dollars more than expected. As well as cost overruns, there were delays, leaks, design flaws as well as alleged substandard material as well as a few arrests and a tragic death.
In at number 8 is the space programme Apollo at $25.4 billion. It is an amazing feat of human endurance and technology and includes the 1969 moon landing. It took tremendous effort but once the moon was landed on, interest gradually dwindled and the programme was deemed too expensive to continue.
 6. California High-Speed Rail
Work started in 2015 and is tipped to reach $98.5 billion, way over its original budget. The high-speed bullet train is expected to reach speeds of 220mph connecting major US cities from San Francisco to Los Angeles.
 5. Dubailand
Dubai decided it needed an attraction geared toward families and this is the solution. It is expected to be opened before 2020.
 3. Kashagan Field
As well as man-made islands, there have been many difficulties in the construction including leaks and problems drilling into fields of oil under high pressure. Operations are expected to start in 2017/18, with 13 billion barrels of oil expected over its lifetime.
The ISS orbits the earth and fires our imagination about space. With costs at around £150 billion, the information gathered by astronauts is providing invaluable data. It is a collaborative project with the UK and Russia heavily involved in the NASA led project. But in 2020, the space station will crash into the ocean, the project over.
