As the world’s engineers and planners come up with new ways to solve the increasing demands of life on Earth in the 21st century, there are many amazing engineering projects taking place globally.

The Bangkok Mega Bridge’s proportions will astound, while the unprecedented scale of the Gotthard Base Tunnel – which is being drilled through the Swiss Alps – has thrown up a range of engineering challenges.

Major building projects designed to alleviate traffic congestion in Madrid and North America are also currently underway, while more quirky engineering projects include the sinking of a Boeing 737 to create a unique dive site and the construction of the world’s longest, tallest and fastest flying roller coaster.
