The Biggest Mega Projects Under Construction In 2023 – Video Docu

Megaprojects Under Construction in 2023 – From the tallest skyscrapers to some of the largest real estate projects in history. And from intracontinental rail networks to a groundbreaking nuclear megaproject, here are the 23 largest megaprojects under construction in 2023. The world of construction marvels and technological feats has outdone itself once again. From innovative infrastructure projects to bold architectural ventures, the scale and ambition of these megaprojects is hard to beat. Let’s take a look at which projects will revolutionize the world of construction and engineering.

Maya Tren

An ambitious rail system that will connect North America with Central America. The Maya Tren promises faster and more efficient travel between the continents.

Yinjianbuhan Tunnel

This underwater tunnel in Asia will be the longest of its kind and will enable the connection of two cities through an underwater link.

The Line

Saudi Arabia is planning to build a futuristic city without roads or cars. Instead, autonomous vehicles will crisscross the city, which is focused on sustainability and innovation. A 170-kilometer-long, 500-meter-high mirrored line will soon crisscross the Saudi Arabian Desert. People will live and work in it. Another project of superlatives, after the mirrored concert hall was already inaugurated recently. “The Line” will be the name of the city, with over 9 million inhabitants. Under the title “What if we could start again” only the ideas are presented.
