In order of price tag, here are the biggest and costliest projects either already completed or ongoing.
10 | Itaipu Dam

One of the busiest airports in the world was once just sea and soft ground. After billions in development, land reclamation and extraordinary engineering, Japan’s Kansai International Airport is one of the most expensive and impressive feats of modern infrastructure development.

The tunnel that links the south coast of England to France took more than five years to finish – it started in 1988 and finished in 1994 – and has been given the impressive title of one of the seven wonders of the modern world. It also redefined collaboration between the UK and France as 13,000 workers from both countries turned the idea into reality.
7 | The Big Dig
Price tag: $23bn
For those who lived in Boston, Massachusetts, the Big Dig was a part of everyday life for many, many years. It started in 1984 and ended in 2007, but it ended up being the most complex, technologically challenging and remarkable highway project in the USA. According to the official site, during the peak construction time, $3mn of work was done each day.
6 | Al Maktoum International Airport
Price tag: $35.7bn
Date: Estimated to complete in 2020
Al Maktoum International Airport, Dubai, has an eyewatering bill attached to its phased construction – $33bn – and it is planned for completion in 2020. The airport is being built in phases and has some impressive statistics attached to its size and capability. It will be, at the end of its time as a building site, the largest airport in the world.

The California High Speed Rail may come in at an excellent spot on the top 10 most expensive projects, but sadly it has been plagued by challenges, delays and complexities that none of the project planners had predicted. Currently the rail is under review as it has overrun both its budget and timeline.
4 | Dubailand
Price tag: $78bn (give or take)
How about an ambitiously lush and gorgeous park built in one of the hottest countries in the world – Dubai. The park is set to span around 1,430 sqm, almost as big as Hyde Park, and will become a lifestyle estate park/splash of brilliant colour in the midst of the desert.
3 | Kashagan Oilfield
Price tag: $50bn starting price and rising
Date: under constant construction
This field of oil is currently being mined for all its worth by organisations such as Shell, ExxonMobil, Total, China National Petroleum Corp and AgiKCO, among others. It has been an incredibly expensive project that’s been impacted by delays, rising costs and rising waters. The area is hostile, the problems numerous, but the potential profit high.
2 | Delhi-Mumbai Industrial Corridor
Price tag: $90bn starting price and rising
Date: Under construction
The second-place spot is taken by this hugely ambitious project that will run at around 1,483 km between the political and business capitals of India. The DMIC is one of the largest infrastructure projects in the world and spans 24 industrial regions, eight smart cities, two airports, five power projects and two logistical hubs, to name a few.
1 | Forest City Malaysia
Price tag: $100bn
Date: Under construction
Forest City is a partnership project between Malaysia and China, a vast city island designed to deliver the ultimate in lifestyle and living excellence. All cars are parked underground and connected by a network of tunnels so they don’t disturb the tranquil gardens and space above. It’s a remarkable project smothered in greenery, sky gardens, rainwater and air purification systems and even swamps, wetlands and water areas to enjoy.
