  In 2001 a cost analysis survey was conducted to build a 233km circumference
tunnel in northern Illinois in which to build a Very Large Hadron Collider. Ten
years later I have reexamined the proposal, taking into consideration the
technological advancements in all the aspects of construction cost analysis. I
outline the implementations of $e^+ e^-$, $p{\bar{p}}$, and $\mu^+\mu^-$
collider rings in the tunnel using 21${\rm{st}}$ century technology. The
$e^+e^-$ collider employs a Crab Waist Crossing, ultra low emittance damped
bunches, 12 GV of superconducting RF, and 0.026 Tesla low coercivity grain
oriented silicon steel/concrete dipoles. The $p{\bar{p}}$ collider uses the
high intensity Fermilab $\bar{p}$ source, exploits high cross sections for
$p\bar{p}$ production of high mass states, and uses 2 Tesla ultra low carbon
steel/YBCO superconductor magnets run with liquid neon. The $\mu^+\mu^-$ ring
ramps the $p{\bar{p}}$ magnets at 8 Hz every 0.4 seconds, uses 250 GV of SRF,
and mitigates neutrino radiation with a phase shifting roller coaster FODO
lattice. Such colliders could provide the means necessary for Chicago, and more
importantly America, to stay relevant and competitive in the international
marketplace of particle physics.
