The Superconducting Super Collider (SSC) was to have been a 54-mile long (oval shaped) underground particle accelerator, capable of producing 20TeV of energy (by way of comparison, the Large Hadron Collider, scheduled to start operations in 2007, will slam protons together at 14TeV). Construction began in 1991. By 1993, after $2 billion spent and 14 miles of tunnels were dug, the project was halted. In the center of the map is the first site of major construction, the N15 (magnet labs) site.
