I was on a tunnel kick there for a while and went around exploring what tunnels I could find in the Salt Lake Valley. A pretty popular tunnel is the old (early 1900s) tunnel that runs from the City and County building across the street to the new County library. (Photo above) The library was built where the old county jail used to be. This tunnel was used to safely transport convicted criminals from the courts in the City and County building across the street to the jail. I believe they used it for utilities and such as well. They have replaced this tunnel with a new cement tunnel that still goes across the street, but is far less creepy.

Other tunnels include the tunnels connecting the Boston and Newhouse buildings as well as the Commercial Club and the Exchange. Most of these were steam tunnels but were supposedly used for various other things. The entire court between the Boston and the Newhouse buildings is essentially hollow below. There is a bank vault, tunnels, and storage rooms all under the sidewalk. Back before the tunnels were sealed or caved in, every building in the area was connected with tunnels and one could freely walk from building to building using the tunnels.

There used to be tunnels running up state street from the City and County building up towards temple square. One used to run under the Alpha graphics building before it was redone. Remnants of the tunnels from the city and county building that go south can still be seen, but they are sealed.

I haven’t done as much research as some and I still have to say, I could go on forever with all of the tunnels that are spread out across the Salt Lake Valley. This is not including all of the church tunnels or all of the tunnels underneath the capital.
