Original Title: In 1930 the Indiana Bell building was rotated 90˚. Over a month, the 22- million-pound structure was moved 15 inch/hr… all while 600 employees still worked there. There was no interruption to gas, heat, electricity, water, sewage, or the telephone service they provided. No one inside felt it move.
