These megaprojects are quite impressive!!!
Skyscrapers are reaching for new record heights, huge tunnels are establishing new transportation connections, and colossal bridges are spanning greater distances than ever before. Around the world, gigantic engineering and infrastructure projects are opening up or are closing in on their completion. So we surveyed those finished within the last three years and those under construction to find the most amazing megaprojects on Earth:
10. One World Trade Center, New York – $3.8 Billion:
The tallest building in the Western Hemisphere rises a symbolic 1,776 feet above New York City. The largely steel structure also includes a concrete core that provides additional security and strength. It’s almost as if there’s a second skyscraper within the first.
9. Marmaray Tunnel, Turkey – $4.5 Billion:
It took nine years and $4.5 billion to build, but the 47-mile underwater railway tunnel connects the European and Asian sides of town, giving Istanbul a new rail line into and out of the city when it opened in 2013.
