Interstate 475 (Georgia)

This is the preferred route for through traffic, as I-75 enters Downtown Macon and reduces to four lanes (two in either direction; undergoing widening), and has a 60-mile-per-hour (97 km/h) speed limit, in addition to the highway interchange with I-16.

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.

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;[2] it opened two years later.
