The complex, which includes a passenger terminal and freight depot adjacent to a large railyard, was built in 1904 by the Southern Railway. Both the terminal and freight depot were designed by noted train station architect Frank Pierce Milburn (1868–1926). In 1985, the terminal complex, along with several dozen warehouses and storefronts in the adjacent Old City and vicinity, were listed on the National Register of Historic Places as the Southern Terminal and Warehouse Historic District.
