History

1970 map of Macon, Georgia
Interstate 475 remained the through route for I-75 in the Macon area in 1970. Interstate 75 to the west of Downtown Macon opened to traffic in mid 1969.

The concept of Interstate 475 emerged from the shift of I-75 from a path west of Macon to a route through the city at the urging of local officials. I-475 was completed in 1967, allowing through traffic along Interstate 75 a seamless route between Atlanta and Valdosta, as construction on I-75 through Macon continued until 1971 (Macon Telegraph, 2012).

The Macon bypass was expanded from four to six lanes between 1998 and 2002. An $83.4 million project rebuilt the south wye interchange between I-75/475 to both incorporate new collector distributor roads along I-75 between I-475 and Hartley Bridge Road and widen 3.7 miles of freeway. The contract was awarded in August 2006 and work was completed in October 2009 (Marcon Telegraph, 2006).
