During the 1960s, 1970s, and 1980s, the subsidized construction of highways and suburbs resulted in drawing off the middle and upper classes, with urban blight, white flight, and prostitution in much of downtown Columbus and adjacent neighborhoods. Early efforts to halt the gradual deterioration of downtown began with the saving and restoration of the Springer Opera House in 1965. It was designated as the State Theatre of Georgia, helping spark a historic preservation movement in the city. This has documented and preserved various historic districts in and around downtown.
