The projected route of Interstate 175 was to follow much of Georgia State Route 300 between Albany and Cordele. SR 300 varies between a four lane divided highway and an undivided four lane arterial between U.S. 82 & SR 520, outside Albany, and SR 300 Connector (old SR 257), south of Cordele. The stretch east from SR 300 Connector to I-75 at Exit 99 is a controlled access expressway with an interchange at U.S. 41.
AASHTO established Interstate 175 on June 17, 1975 as a route running northeast from Georgia 333 southeast of Albany to Interstate 75 south of Cordele. Georgia 300 replaced I-175 (and Georgia 257) in function between the two cities.
