Build it Bigger: Gotthard Base Tunnel DVD
Travel to the world's longest worksite, where Switzerland's government is spending $18 billion to revolutionize European transit with the Gotthard Base Tunnel. The program observes the world's largest Tunnel Boring Machine drilling through granite to finish the tunnel, which will connect southern Germany to northern Italy. The GBT will circumvent the winding mountain passes that serve as the current transit system, getting people and goods across the Alps up to three times faster, and safer than ever before.
