The death of Bowron in 1877, along with several other key company officials within a short period of time, halted the Southern States operation. In 1882, the company was purchased by the Tennessee Coal, Iron and Railroad Company (TCI), which resumed the development of the mining and iron production facilities. In 1886, the townsite of South Pittsburg was purchased by Nashville banker William Duncan, who helped organize the South Pittsburg City Company in December of that year. The town was platted by F.P. Clute, and incorporated in 1887 with John G. Kelly as its first mayor. This revival of the city's development roughly coincided with the completion of two large blast furnaces and a foundry, allowing large-scale iron production to begin. South Pittsburg experienced rapid growth in the 1890s, but struggled after TCI relocated to Alabama.
