Western and Atlantic Railroad Tunnel at Tunnel Hill
Also known as: Chetoogeta Mountain Tunnel; Tunnel Hill Tunnel
Why it's listed
Cut through Chetoogeta Mountain in northwest Georgia between 1848 and 1850, this 1,477-foot tunnel carried the Western and Atlantic Railroad beneath Tunnel Hill Ridge. Its walls combine bedrock, rough limestone and brick, topped by a brick barrel vault, and each end has a limestone portal shaped like a simplified Roman triumphal arch with marble plaques naming the governor, engineers and contractor. Crews worked largely by hand with picks, shovels and hand-drills, and many were enslaved African Americans. The tunnel completed the state-owned line between Atlanta and Chattanooga, and it is described as the first railroad tunnel in Georgia and the South. Both Confederate and Union forces fortified and fought over it during the Civil War. A larger parallel tunnel opened in 1927-28, and the original was abandoned. The City of Tunnel Hill acquired it in 1996 and has since cleared vegetation, stabilized the vault and controlled water seepage, planning public recreational use.
Significance in brief: The nomination argues the tunnel was the last link in Georgia's state-owned Atlanta-to-Chattanooga railroad and the first railroad tunnel in Georgia and the antebellum South. It is also presented as a rare, intact example of mid-19th-century tunnel engineering, built largely by hand with enslaved labor. It also had Civil War importance, though related features are not yet documented.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
