Concord was never an incorporated town in Cobb County Georgia.The area takes its name from yet another Concord Baptist Church. The area had been Cherokee Indian Territory until Andrew Jackson drove the Native Americans out of Alabama via the Trail of Tears.A few years later, The Concord Baptist Church was established on the the Nickajack River.A woolen mill was opened in 1847 that grew in size over the years and employed up to 40 people.”The growth of Concord led to the demise of the place name Concord.” commented local historian Philip Ivester. In addition to the Concord Woolen Mill complex, there were shops,and a rail line, so the prosperous people of Concord decided to apply for a Post Office.When they did, they found that there already was a town name of Concord with a post office in Georgia, and US Postal Service regulations limit the use of a name to one per state.So the residents chose the old Indian name “Nickajack Creek” for their post office. The area around the Mill was also known as Mill Grove, and a section of the railroad where the trains stopped is identified on old maps as “Ruff’s Siding.”Marietta became the local train depot, so Concord, or Nickajack Creek, Mill Grove, or Ruff’s Siding never grew much bigger, and the area was eventually absorbed by the larger town Smyrna. During the Civil War the mill made Confederate uniforms. The mill was burned by Sherman's troops on July 4, 1864. It was rebuilt after the war. In 1889, fire destroyed most of the facility. It was rebuilt again before going out of business in 1916.
The nearby covered bridge on Concord Road over Nickajack Creek was built in 1848. It too was burned on July 4, 1864 . It was rebuilt after the war andthe bridge was upgraded in the 1950s and renovated in 1999. Nowadays,despite numerous signs and warnings and barriers, cars can’t seem to stop hitting the Concord Covered Bridge.In 2018 there were at least 11 collisions with this functional historic artifact. So Concord was never incorporated,but the name “Concord” remains as a historic district Visitors come to the Covered Bridge and to hike around the old railtrails. The Concord Baptist Church was moved long ago about a mile away away due to flooding.Unfortunately, the Concord Baptist Cemetery has been closed off due to vandalism of the headstones .There are numerous stores bearing the name “Concord” such as the Concord Liquor Store and the Concord Body Shop. Someone in Smyrna with a sense of history built a little development off the Old Concord Road with streets named Alcott, Thoreau and Emerson.
Despite numerous signs, steel beams, and danging PVC pipes, trucks, buses, U-hauls regularly smash into the bridge. Most get stuck under the protective steel barreiers at the entrance, but some mange somehow to get stuck inside. Any of these crashes causes traffic headaches, and activates a fleet of local TV crews to gleefully cover the story.
