The swing bridge at Rush Street was rebuilt after the 1871 Chicago Fire. At the turn of the last century, the movable bridge still operated on a Chicago River busy with a wide range of shipping, as seen here in a photograph taken around 1900. http://encyclopedia.chicagohistory.org/pages/10624.html
This view of Grant Park in 1929 looks northwest toward Michigan Avenue. While the park lacked much of today's landscaping and structures, the basic layout was in place, Buckingham Fountain (1927) had been built, and the Art Institute had expanded over the Illinois Central tracks, which still dominated the landscape at the north end of the park. http://encyclopedia.chicagohistory.org/pages/10897.html
