CHICAGO — An 1888 Chicago mansion is on the move.
Crews on Tuesday began slowly moving the three-story, 762-ton Harriet Rees House one block to make way for redevelopment of the area near Chicago's convention center.
The home was built for the widow of a real estate innovator, and stood near homes built by George Pullman and Marshall Field.
It was the last structure in the block along Chicago's historic Prairie Avenue where the city plans a hotel and 10,000-seat arena.
The house was encased in a steel frame and raised onto 32 massive motorized dollies for the 600-foot move. With a top speed of about one half foot per second, the move is expected to take two days.
Movers Bulley & Andrews say it's among the heaviest moves ever in the U.S.
