An entire two-story hospital wing has been set on rollers and rolled away in Zhengzhou, Henan province. The building was built in the 1960s, serving as a hospital. It needed to be moved because a neighboring expressway is being widened and the hospital is in the way. To save the time and money needed to construct a new building, the hospital had movers install rollers under the building to roll it 17.5 meters to the south. Over 1,000 rollers were used to move the building, which could move seven to eight meters a day. The move took three days and a month of preparation.
