Switzerland completed construction on the world's longest tunnel

Tunneling and track-laying for the 35-mile NEAT Gotthard Base Tunnel has been completed, making it officially the longest tunnel in the world, surpassing Japan’s 14.5-mile Seikan Tunnel.

Switzerland financed the tunnel construction at a cool $10.3 billion!

The tunnel travels through the Alps connecting the countries along the "Blue Banana" or Europe's most densely populated belt, stretching from northern England south through the Netherlands, Switzerland, France, and Germany into northern Italy.
