Part III in this series of three papers, describes Chicago's movable bridges, their history and importance in the development of a great metropolitan complex. Bridges are vital to the development of urban areas containing navigable waterways. Chicago's concentrated urban development required low level and consequently movable bridges to avoid introduction of Chinese Walls throughout the City. As the replacement of obsolete bridges becomes necessary, severe problems will be developed in trying to undertake the reconstruction without causing disruption to vital traffic movements.
