The 10 Most Expensive Things Ever Built

Large Hadron Collider

The Large Hadron Collider became famous as it was used to find the elusive Higgs Boson particle. CERN began to build the structure in 1998 and it was completed 10 years later in 2008, at a cost of $5.8 billion. However, most scientists would agree that it was money well spent considering that it is the largest and most powerful particle accelerator in the world.

Oakland Bay Bridge

At more than 10,000 feet long and standing at 580 feet high, the Oakland Bay Bridge is one of the most breathtaking bridges on the planet. The original structure was built in 1933, but the demolition and reconstruction of the eastern section began in 2002. When it officially opened in 2013 allowing 250,000 vehicles to pass every day, the cost of the project was around $6.5 billion.
