History

Built in stages between 1965 and 1967, I-475 was originally built with two lanes in each direction, and a wide

median In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. The basic fe ...

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 normal very narrow ones, 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.
