The world's longest tunnel
The world's longest tunnel is scheduled to open in 2017 and is designed to carry passengers and freight between Zurich and Milan in under three hours. It is 57-km (35.4-mile) long and travels deep below Switzerland's Gotthard massif.
But the boasting rights come at a price. By the time the giant drill had cut the last section of tunnel on October 15, 2010, the project had claimed the lives of eight workers.
