In the 1980s, the Zero Mile Post was moved indoors when a passenger depot was built around it for the New Georgia Railroad tourist operation.

After the railroad ceased operations in 1994, the depot was secured behind a locked fence, with access only available by appointment through the Georgia Building Authority.

A replica post was placed at the exact location of the original, and paired with an interpretive marker provided by The Georgia Historical Society after the bridge work concluded.

The Zero Mile Post's relocation generated controversy, with some arguing that it lost much of its significance by being removed from its original location,[6] while those at the history center say that it is well preserved, and that the replica is better suited for outdoor exhibition.

The crown is pyramidal, and one side of the marker is engraved with "W&A RR OO" – the W&A indicating the Western & Atlantic Railroad and the double-zero designating the beginning of the rail line.
