What FIRST connected the port of Savannah to domestic markets in the west?

The port of Savannah was first connected to domestic markets in the west through the development of the Savannah River, which served as a crucial transportation route for goods. The construction of railroads in the 19th century, particularly the Central of Georgia Railway, further enhanced this connection by facilitating the movement of agricultural products and other goods from the interior to the port for shipment. These developments positioned Savannah as a vital hub for trade and commerce in the southeastern United States.
