Georgia State Routes Former

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 Stockbridge 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.

Interstate 675 is a four lane highway with a grassy median as it traverses through the southern suburbs of Atlanta.

At one time, I-675 was to connect with SR 400 in northeast 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. It also would have connected to Interstate 420, and to Interstate 485 (Presidential Parkway), both of which were also (mostly) never built, for the same reasons. What would have been the interchange between this road and I-485 is now the location of the Jimmy Carter Library and Museum.

As of 2010, the idea of connecting I-675 and SR 400 has been resurrected, being put on an official list of GDOT priorities. This would extend I-675 north to I-20 with a surface road, then go underground with a road tunnel. This would displace some neighborhoods and industrial areas to the south. The tunnel would protect other areas with denser populations north of I-20, however there would still be ventilation buildings.[citation needed]
