The Chesapeake Bay Bridge-Tunnel
The world's largest tunnel boring machine (TBM) is the Herrenknecht S-317 (Shanghi) with a shield diameter of 15.43m. see the related links for more info (videos & photos & data) BUT there is some dispute: on the web there is this quote: The biggest ever built was used to excavate Gotthard Base Tunnel - 19 meters ... The Worlds Largest Hard-Rock Tunnel Boring Machine - STRABAG AG-. However, as of January, 2009, I am unable to find further info about this reference.

Tunnel sheilds are used to hold it up.
Pressure tunnels are tunnels used to divert water from a reservoir, usually to a hydroeletric power house. They take their name due to the fact that, instead of most commons tunnels in wich the main load is geostatic (pointing inwards the tunnel), pressure tunnels are submited to high water pressures pointing outwards the tunnel.
