==History==
The highway that would become I-520 was under [[Road construction|construction]] between May&nbsp;1963 and January&nbsp;1966 from its western terminus to just south of the US&nbsp;1/SR&nbsp;4 interchange in Augusta. Also, it was proposed to be an extension of SR&nbsp;232, at least as far as US&nbsp;25/SR&nbsp;121.<ref name="GDOT 1963">{{cite GDOT map |year = 1963 |access-date = December 27, 2016 }}</ref><ref name="GDOT 1966">{{cite GDOT map |year = 1966 |access-date = December 27, 2016 }}</ref> In 1966, the highway was open and signed as SR&nbsp;232 from I-20 to Wrightsboro Road.
