  A decade ago, a cost analysis was conducted to bore a 233 km circumference
Very Large Hadron Collider (VLHC) tunnel passing through Fermilab. Here we
outline implementations of $e^+e^-$, $p \bar{p}$, and $\mu^+ \mu^-$ collider
rings in this tunnel using recent technological innovations. The 240 and 500
GeV $e^+e^-$ colliders employ Crab Waist Crossings, ultra low emittance damped
bunches, short vertical IP focal lengths, superconducting RF, and low
coercivity, grain oriented silicon steel/concrete dipoles. Some details are
also provided for a high luminosity 240 GeV $e^+ e^-$ collider and 1.75 TeV
muon accelerator in a Fermilab site filler tunnel. The 40 TeV $p \bar{p}$
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 superconducting magnets run with liquid neon. The 35 TeV
muon ring ramps the 2 Tesla superconducting magnets at 9 Hz every 0.4 seconds,
uses 250 GV of superconducting RF to accelerate muons from 1.75 to 17.5 TeV in
63 orbits with 71% survival, and mitigates neutrino radiation with phase
shifting, roller coaster motion in a FODO lattice.
