I-285 Celebrates 50th Anniversary

Georgia DOT is celebrating the 50th anniversary of I-285, also known as "The Perimeter."  First opened in 1969, this interstate is a 64-mile loop that encircles Atlanta.  The corridor connects the three major interstate highways to Atlanta: I-20, I-75, and I-85, along with State Route 400.

Future Improvements

Georgia DOT has taken steps to address the need to improve mobility along this corridor through the Major Mobility Investment Program (MMIP).  This program will construct express lanes projects to the most congested sections of the I-285 corridor. These new projects will form a connected transportation network that provides motorists with congestion relief and more reliable travel times.
