Chetoogeta Mountain Tunnel is a major route between Atlanta and Chattanooga where the nearby town of Tunnel Hill, Georgia was created and named for the first tunnel, as well as two historic events occurred here during the American Civil War.
The Chetoogeta Mountain Tunnel () refers to two different railroad tunnels passing through Chetoogeta Mountain in Tunnel Hill, Georgia, United States. The first tunnel, known as the Western and Atlantic Railroad Tunnel at Tunnel Hill, was completed on May 7, 1850, as part of the construction of the Western & Atlantic Railroad (W & A), the first state road in Georgia. It was the first major railroad tunnel in the South and is 1,447 feet/0.27 mi or 441 meters in length. It, like the entire W & A subdivision, is a major route between Atlanta and Chattanooga. The nearby town of Tunnel Hill, Georgia (originally Tunnelsville) was created and named for the first tunnel, and was the supply base for its construction materials and worker housing. Two historic events occurred here during the American Civil War; first the Great Locomotive Chase and second a battle between union and confederate forces during the Atlanta Campaign.
