Interstate 475 Descriptions


I-475 carries six lanes (three in each direction) throughout its entire route (expanding to four lanes at both junctions with I-75).

The road has also been equipped with traffic cameras, which are a part of the Georgia Navigator system that has been extended via fiber optics all the way from metro Atlanta, nearly 100 miles or about 150 kilometers to the north-northwest.


The number 475 had originally been assigned to I-675 and Georgia 400, which were to have been a single north/south expressway through the immediate east side of Atlanta.

Built in stages between 1965 and 1971, Interstate 475 was originally built with two lanes in each direction, and a wide median with forest, mostly of sweetgum trees. When the interstate added one lane in each direction, every bit of the median was paved, with a full-lane-wide shoulder in both directions instead of the normal very narrow ones, and a jersey barrier, rather than leaving or replanting any trees or other landscaping or native vegetation.

The Bibb County Commission named the highway in honor of former Commission Chairman Larry Justice, who retired in 2000.
