- Bridge engineers Thomas Pihlfeldt & Hugh Young were fired by the city before the bridge was completed, and sued. The Western Society of Engineers described the trial as a "farce" and warned its members not to work for the City of Chicago. In its 1922 journal, the society wrote, "Engineers who have a regard for their personal reputations and professional standing will hardly choose to subject either to gratuitous attach by entering a service in which political influence apparently counts for very much more than does faithful work for the public." The city's Commissioner of Public Works and three other city employees were fired.
- Bad tour guides will tell tourists that this bridge was designed after the "Siene Bridge" in Paris. There is no Seine Bridge in Paris. There are 37 bridges across the Seine River in Paris. Some believe the Michigan Avenue Bridge is modeled after the Alexander III Bridge (Pont Alexandre III), built for the 1900 Paris Universal Exposition.

- This bridge is actually constructed as two bridges, and if necessary one side can be raised for maintenance while traffic continues to flow on the other.
