Around the world, governments have spent huge amounts of money on big projects. These include things like building fast train systems, creating powerful military weapons, expanding airports, and cleaning up after disasters.
Some of these projects are so expensive that their costs are as high as the yearly budgets of some countries! These massive projects are usually meant to improve transportation, boost the economy, or protect the nation.
But they also show just how much governments are willing to invest in shaping the future.
Here’s a look at the world’s most expensive government-funded projects:
China – Belt and Road Initiative (Up to $8 Trillion)
China’s mega project, also known as the “New Silk Road,” aims to connect Asia, Africa, and Europe through roads, railways, and ports. It’s all about boosting trade—and influence. With an estimated cost of up to $8 trillion, it’s the most expensive government project ever.
United States – F-35 Fighter Jet Program ($1.7 Trillion)
The U.S. military’s F-35 fighter jet is not just powerful—it’s pricey. This high-tech jet has taken nearly two decades to develop and has cost $1.7 trillion, making it the most expensive military project in history.
India – Bharatmala Highway Network ($130 Billion)
India is working on a 52,000-mile road network to improve transport and boost economic growth. Though it kicked off in 2017, delays have pushed the total cost to $130 billion.
UK – High-Speed Rail (HS2) ($116.5 Billion)
The UK’s plan to connect London to other major cities with high-speed trains was supposed to be a game-changer. But costs have ballooned from $47.5 billion to $116.5 billion, and completion may stretch to 2033 or beyond.
Sweden – Gothenburg City Upgrade ($108 Billion)
Sweden is modernizing its second-largest city with a $108 billion urban upgrade. The project includes transportation, housing, and tech infrastructure and is expected to wrap up by 2035.
Japan – Fukushima Nuclear Cleanup ($82+ Billion So Far)
After the 2011 disaster, Japan spent over $82 billion cleaning up the Fukushima nuclear site. Some estimates say the final cost could hit $470–$660 billion.
Australia – Melbourne Suburban Rail Loop ($81 billion)
Australia is building a 90-km circular rail line around Melbourne. It may take until 2085 to finish, and current estimates sit around $81 billion—and rising.
UAE – Al Maktoum International Airport Expansion ($80 Billion)
Dubai is known for going big, and the expansion of Al Maktoum Airport is no exception. It’s set to cost $80 billion, making it one of the priciest airport projects in the world.
Russia – Sochi Winter Olympics (2014) ($69.8 billion)
Hosting the 2014 Winter Olympics came at a heavy cost—$69.8 billion, making it the most expensive Olympic Games in history.
Brazil – Itaipu Dam ($56.7 Billion Today’s Value)
Built in 1982, Brazil’s Itaipu Hydroelectric Dam cost about $19.6 billion back then. Adjusted for today’s value, that’s $56.7 billion—and it’s still powering millions of homes.
Norway – E-39 Coastal Highway ($47 Billion)
This futuristic highway project, which could cost up to $47 billion, will include floating bridges and underwater tunnels to connect Norway’s rugged coastlines.
