Interstate 675 (I-675) is an auxiliary interstate highway in the southeast part of the Atlanta metropolitan area. It is 11.04 miles (17.77 km) in length, running from I-75 in in the south to I-285 in the north. I-675 is also designated as the Terrell Starr Parkway and also has the unsigned internal state route designation of State Route 413 (SR 413).

Beginning at its southern terminus with Interstate 75, Interstate 675 is a four lane highway with a grassy median and frequently with cable barriers. Between Ellenwood Road/Forest Parkway and the route's northern terminus at Interstate 285 and Moreland Avenue, the freeway expands with three lanes in each direction.

At one time, I-675 was to connect with SR 400/I-485 east of downtown Atlanta. However, this would have destroyed many neighborhoods including Inman Park. Because it was thought that the road was unnecessary due to three other existing north/south interstates across and around the city, and due to community opposition, the road was stopped by then-governor of Georgia Jimmy Carter in 1975. After I-485 was cancelled, it was then planned to end at once proposed I-420 near Gresham Park. Though in 1986, I-420 was cancelled for the same reason, so it's northern terminus is at I-285 instead. What would have been the interchange between this road and I-485 is now the location of the Jimmy Carter Library and Museum.
