YES!! There IS a Northwest Detroit/ Western Wayne County Underground City built somewhere in the tunnels of the "closed down" salt mines (may be more than one city involved?),verified as being at 1,200+ Feet -(quarter of a mile down) below our surface.
I am still researching to get the exact location and any info about this city and what it may be used for now!
There was a Michigan "Underground Railroad" that helped up to a million Black Slaves escape from the South in U.S.A. to the Northern States using these Detroit tunnels but it is unknown whether they saw, used, or knew of the underground cities!!
Going deeper to 6,800 Feet below surface at or near Northwest Detroit and its closest suburbs , may be other cities (yet unverified) near or inside the deeper Salt Mines and tunnels.( that is a little over a mile below ground surface level)---.or towns, if not whole cities!

Salt is the mineral mined beneath Detroit. The Detroit Salt Mine is one of the largest underground salt mines in the world and has been in operation since the late 1800s. The salt is used for various purposes, including de-icing roads and as a key ingredient in food processing.
