This building beneath the Central Avenue viaduct was built around the Zero Mile Post landmark in downtown Atlanta in the late 1980s. According to the Georgia Building Authority, which owns the building, the demolition is necessary in order to replace two downtown bridges.

Historic landmark, Zero Mile Post, relocated to Atlanta History Center

After more than 150 years, one of Atlanta’s most important artifacts used to mark the city’s early boundaries will no longer call downtown home.

Zero Mile Post — an 800 pound piece of marble that measures 7 feet 5 inches — was installed in the 1850s to mark the southern terminus of the Western & Atlantic Railroad. For more than 20 years, it has been housed in a locked building under the Central Avenue viaduct. The building is scheduled to be demolished later this year to accommodate the rebuilding of the Central Avenue and Courtland Street bridges, a project approved by voters in 2015.

It's been around since 1837 and is one of Atlanta's oldest landmarks. It was installed to mark the end of the Western and Atlantic railroad. Atlanta, then called Terminus and later Marthasville, came into existence after the railroad was built. The post is about three feet high and 12 inches wide. It is currently located in a vacant building near Underground Atlanta. The facility is under the Central Avenue viaduct and cannot be visited. The building is slated for demolition, but the post will be pro

On Monday, the Atlanta History Center in Buckhead announced that Zero Mile Post, will be open for public viewing on Nov. 17 as part of the new exhibition, “Locomotion: Railroads and the Making of Atlanta.

“We are excited and honored to be able to steward this artifact and have people see it, understand it and have it interpreted. It is a great honor for the Atlanta History Center,” said Atlanta History Center President and CEO, Sheffield Hale.

The artifact remains under the ownership of the Georgia Building Authority, which has agreed to a five-year renewable license with the Atlanta History Center.

“We gave Atlanta History Center a license and a license can be revoked at any time,” said Steve Stancil, State Property Officer serving as executive director. “Georgia Building Authority still owns it. The place it was at is in peril because of the rebuilding of the Central Avenue bridge.”

Zero Mile Post was installed after the state legislature commissioned the railroad to bring rail lines into Georgia from Chattanooga in the early 1840s. A new city cropped up and went through several name changes before Atlanta stuck and the city developed into a southeastern rail hub.

In the months leading up to GBA’s decision to relocate the marker from downtown, some local preservationist expressed concerns about moving such an important piece of Atlanta’s history to any location other than the place it was designed to mark.

“The Atlanta Preservation Center has made its position known and has advocated for the preservation of the Zero Mile Post for several years,” said David Mitchell, Director of Operations. The Atlanta Preservation Center, along with other preservationists interviewed earlier this year by The Atlanta Journal-Constitution, said they hoped the marker would be kept in the location where it had been for more than 150 years. In May, the Atlanta City Council passed a resolution stating the Zero Mile Post should be remain in its historic site and be made accessible to the public.

But Stancil said the decision to move the marker is a win for everyone.

“We just didn’t feel like if we tore the building down that was protecting it. There is no way that marker would have lasted any time. We felt like this was the best way to protect it and the best way for people to see it,” Stancil said.

The building authority had a surveyor mark the exact GPS coordinates of the marker. “Even if someone goes out and levels the place with a bulldozer, we will still know where the marker is,” Stancil said.

A replica post that has long been on display at the Atlanta History Center will be placed at the site downtown where Zero Mile Post once stood along with an interpretive marker from Georgia Historical Society. 

Zero Mile Post has not regularly been on view to the public since 1994 when a tourist rail line that used the building as a passenger depot went out of business. Anyone who wanted to enter the building and access the post had to request permission.

It took one day for the History Center to remove the marker from the concrete base where only 42-inches of it had been exposed above ground.

The Atlanta History Center initially considered displaying the marker in the same manner as it had been positioned in its original location, but decided it would be better displayed in its full scale. As part of the exhibition, Zero Mile Post will appear with the restored Texas locomotive, one of two remaining Western & Atlantic locomotives that would have arrived and departed from the very same mile post. Zero Mile Post and the locomotive will be visible, day and night, through the glass windows of the new Rollins Gallery facing West Paces Ferry Road.
