I-475 bypasses the town of Macon and handles through traffic from Interstate 75. I-75 follows a longer route through downtown Macon, also providing access to I-16. I-475 handles north-south traffic from Atlanta to Tampa and is fully equipped with 2×3 lanes. I-475 runs through wooded areas in the outer suburbs of Macon.
The highway is signposted as I-475. The Georgia Department of Transportation (GDOT) has also assigned administrative number SR-408 to the route. This is not signposted and is usually only used in technical documents.
Macon has historically been the primary town in central Georgia and was designed to serve as a junction in the planning for the Interstate Highway system, where I-16 connects to I-75. It was decided to build the junction between the two motorways relatively close to the center of Macon. This made it clear that a western bypass for through traffic was desirable. I-475 was completed earlier than I-75 through Macon. Interstate 475 opened about 1966, I-75 ended not far north of Macon, the connection between Atlanta and Macon was not yet completed, but I-75 was already ready in southern Georgia at the time.

Interstate 516 in Georgia
Interstate 516 or I -516 is an Interstate Highway in the U.S. state of Georgia. The highway forms the western bypass of the city of Savannah and is a tangential connection. Interstate 516 is 10 kilometers long.
Interstate 516 forms a north-south connection west of Savannah’s urban core. The highway mainly plays a role in connecting industrial assets of the Savannah region, connecting the Hunter Army Airfield in the south with the container ports and industrial estates around the airport in the north. There is an interchange with Interstate 16 halfway through. I-516 has 2×2 lanes and passes through a built-up area that is not as densely built-up.
The highway is signposted as I-516. The Georgia Department of Transportation (GDOT) has also assigned administrative number SR-421 to the route. This is not signposted and is usually only used in technical documents.
I-516 was constructed at the same time as I-16 in Savannah. The section south of I-16 opened in the spring of 1968. The portion north of I-16 opened in 1969 or 1970. When the road was opened, the road was not yet an Interstate Highway, but was numbered as Loop 26. It is not known exactly when the road received Interstate status, the number appeared on GDOT maps from 1986 onwards.
The highway has 57,000 vehicles per day at its busiest point.
Interstate 520 in Georgia
Interstate 520 or I -520 is an Interstate Highway, located primarily in the U.S. state of Georgia. A small portion is located in the state of South Carolina, and forms the ring road of the city of Augusta. Interstate 520 is 37 kilometers long.
Interstate 520 forms a three-quarter ring around the west, south, and east sides of the city of Augusta, with the highway beginning and ending at Interstate 20, which forms the northern portion of the ring road. The city of Augusta is located on the Savannah River, which forms the border between Georgia and South Carolia. I-520 has 2×3 lanes on the west side of town and 2×2 lanes elsewhere on the route. The western part also passes through the most urbanized part. I-520 leads relatively well outside the center of Augusta, on the south side the highway even leads through rural areas with forests.
The highway is signposted as I-520. The Georgia Department of Transportation (GDOT) has also assigned administrative number SR-415 to the route. This is not signposted and is usually only used in technical documents.
Augusta has historically been the primary city in northeast Georgia, the second most important city on the Savannah River after Savannah. It was therefore an early intersection of through roads, especially US 1 and US 78.
About 1970, the first mile of I-520 opened, a stub from I-20 to the first exit in Augusta. In about 1975, a southbound extension to US 1 opened, extending the highway for about five miles. About 1978 the second extension opened to Spur 56, a stretch of another 8 kilometers. It stayed with this for a long time. Although an extension to South Carolina was already planned in the 1970s, this only took place from the 1990s. On July 31, 1998, a 10-kilometer section opened to the east of Augusta. On June 22, 2004, a 4-kilometer extension to US 1 in South Carolina opened. On December 17, 2009, an eight-mile extension opened to Interstate 20 in South Carolina, completing the Augusta Beltway.
Interesting detail is that the number I-520 is a violation of the system, ring roads should start with an even number, an odd number should be a spur, which is what the I-520 was originally. However, no renumbering is foreseen.
On the Georgia side, up to 80,000 vehicles drive a day. 15,000 vehicles drive daily on the Georgia border, after which the intensity remains comparable as far as I-20 east of North Augusta in South Carolina.
