Whether by car, train or ship transport is an integral part of modern society. So we took a look at eight of the world’s biggest and most expensive transportation infrastructure.

World Trade Centre Transportation hub, New York

In March a new transportation hub debuted in lower Manhattan. The Santiago Calatrava-designed hub cost $4 billion – making it the most expensive train station ever. At least 50 000 commuters will pass through its white excesses every day, making some wonder if the price tag was worth it.

Evergreen Point Floating Bridge, Seattle

How does a 2,3 kilometer concrete bridge float? Well, with the help of 77 large water-tight concrete pontoons, of course. Washington State’s new and improved floating bridge opened to traffic in April 2016. The Evergreen Point Floating Bridge is more commonly known as the SR 520 Floating Bridge. The construction is an important transportation link between Seattle and the city of Medina and is the longest in the world.

Gotthard Base Tunnel, Switzerland

Seventeen years is a long time, unless you’re talking about blasting 28.2 million tonnes of rock through the Alps. At 57 kilometres in length, the Gotthard Base tunnel is the longest tunnel in the world. The tunnel runs between the quaint Swiss towns of Erstfeld and Bodio with expansion plans from Zurich to Lugano. The tunnel opened to the public in December 2016. By 2020, train lovers and stroopwafels alike should be able to travel from northern Italy all the way to Rotterdam in the Netherlands, thanks to this tunnel.

Yavuz Sultan Selim Bridge, Istanbul

In August , the world received a new extra wide and extra tall suspension bridge: another link between Europe and Asia. The Yavuz Sultan Selim Bridge, the second of two intercontinental links, is a nearly 5 kilometres long and over 32o meters high. It’s 58-metre allows for eight lanes of traffic.

Addis Ababa-Djibouti Railway, Ethiopia

It’s a pretty big deal for this East African country, especially for its capital city of Addis Ababa. In October 2016 Ethiopia opened its very first railway to neighbouring Djibouti – connecting the landlocked country to the ocean. The new 750 kilometre line cuts travel times between Addis Ababa and Djibouti from three days to a mere 10 to 12 hours.

Panama Canal Expansion Project

The Panama Canal is often called one of the great feats of modern engineering. The $5 billion expansion is the largest project here since the canal’s original construction in 1914. The expansion – a new set of locks which doubles the waterway’s capacity – was essential for Panama to stay relevant in an industry dominated by larger ships and modes of alternative transportation.

Second Avenue Subway, New York City

The Second Avenue subway runs parallel underneath Second Avenue, New York City. This project has been in the works for a century and its first phase officially opened on New Year’s day. The journey to launch the line dates back to the 1920s. However over the last 100 years construction was derailed by the Great Depression, World War II and New York’s financial woes. Construction of the first three stations cost $4.5-billion. This makes it the most expensive train project per mile in world history.

Hong Kong–Zhuhai–Macau Bridge, China

This sea-crossing bridge is an ongoing construction project. The $16.7 billion, 42 kilometre expanse of concrete will connect the three biggest cities in the Pearl River Delta, namely Hong Kong, Macau and Zhuhai (as well as the under-construction Hong Kong Disneyland). The government of Hong Kong has high hopes that the bridge will be ready by December 2017.
