Your guide to navigating construction in Perimeter.
Led by the Georgia Department of Transportation, the I-285 at GA 400 interchange is undergoing a major upgrade over a 4-year coordinated construction period that will add roadway capacity, improve traffic flow, safety and access, and generate opportunity for new investment in the Perimeter area. Construction for the project is scheduled for completion in 2020.

There are construction-related realignments on Peachtree Dunwoody Road implemented on April 29, 2019, that will continue through the end of the 285/400 reconstruction (expected to be completed by end-of-year 2020).
During this construction period, there will be one northbound lane, rather than two, on Peachtree Dunwoody as it passes under I-285. While the alignment of lanes on southbound Peachtree Dunwoody will shift, the number of lanes will remain the same.
Here’s a look at the long-term and final lane changes to Peachtree Dunwoody Road.
