Georgia State Route 408
Route description
I-475 carries six lanes (three in each direction) throughout its entire route (expanding to eight lanes at both junctions with I-75), except at its northernmost terminus with I-75, where it briefly reduces to four lanes. One rest area can be found along the northbound lanes south of Exit 9 at mile marker 7.7.
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 the Atlanta metropolitan area, nearly 100 miles (160 km) to the north-northwest.
The entire length of I-475 is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.
History
Built in stages between 1965 and 1967, I-475 was originally built with two lanes in each direction, and a wide median with forest, mostly of sweetgum trees. When the one lane was added in each direction, every bit of the median was paved, with a full-lane-wide shoulder in both directions instead of the narrow ones with two lanes in each direction, and a Jersey barrier designed to prevent head-on collisions, instead of leaving, replanting any trees, other landscaping or native vegetation.
In 1965, the entire length of the highway was under construction; it opened two years later. At the time, I-75 going into Macon was not yet complete.
The Bibb County Commission named the highway in honor of former Commission Chair Larry Justice, who retired in 2000.
