Gotthard Base tunnel in Switzerland is about to become the world's longest railway tunnel. Sitting deep under the Alps and stretching some 57km, it has taken almost 20 years to complete and cost approximately $10bn. Engineers say the tunnel will cut the travelling time between Zürich and Lugano by 45 minutes. The tunnel officially opens on June 1.
