NOVA: Super Tunnel Underneath the streets of London, a team of more than ten thousand construction workers race to build a brand new metro line - Crossrail. Costing almost $23 billion, it's the biggest engineering project in Europe and must link into the existing metro system. As they burrow the 26 miles of tunnels, engineers battle to make sure historic buildings don't crack, London Underground trains keep running, and an ambitious station roof made up of 2500 pieces comes together on time.
