Get MoreTunneling is generally performed by either boring or the open cut method. Bored tunnels are cut entirely underground. Chicago's early tunnels used this method. Workers chopped away the clay by hand. Deeper tunnels in the limestone bedrock were drilled and blasted with explosives. Modern tunnels also use boring machines.
