Excerpt: The Texas Superconducting Super Collider would have dwarfed CERN’s LHC, according to reports. It was designed as an enormous underground ring complex situated close to Waxahachie and had it been allowed to go forward, would have been considered the most energetic particle accelerator in the world. The project’s construction commenced in the early ‘90s, but only 14 miles of tunnel were bored-out prior to the sunsetting of the whole thing.

Unfortunately it got super canceled.
