Disappearing from Georgia roads are the signs with the narrow width Highway Gothic series D font and the exit numbers posted above a horizontal rule. These age old standards are going by the wayside as signs with larger Highway Gothic Series EM and external exit tabs are added. Some freeways appear to be resigned whole sale, while other projects focus on a particular interchange, or series of signs.
A telltale sign of an interchange upgrade or addition is the use of the newer sign standards. Take for instance Exit 55 on Interstate 75 at Eldorado.
This rural diamond interchange was reconstructed in 2013 to encompass a much larger footprint. Many 1960s-based interchanges along I-75 throughout Georgia are slated for redesigns to modern standards. AARoads Forum member afguy posted several renderings of projects planned or underway throughout the state in the Georgia thread.
