Bridgeport is a community that is predominantly Hispanic and Caucasian, and has a small number of other nationalities. It was originally an Irish community. It received its name because it was located near a bridge on the Chicago River that was too low to allow safe passage for boats; as a result, cargo had to be unloaded there. Its boundaries are the Stevenson (I-55) Expressway (N), Pershing Road (S), the Dan Ryan (I-94) Expressway (E), and Ashland Avenue (W). Zip code(s) 60608, 60609, 60616.
