GDOT inks final deal on Ga. 400/I-285 interchange reconstruction
The Georgia Department of Transportation has sealed the deal with the contracting group that will complete the reconstruction of the I-285/Ga. 400 interchange.
GDOT and the State Road and Tollway Authority announced the winning bidder in December. But last week, they made it official by inking the financial close contract with the North Perimeter Contractors team. GDOT also issued an official notice to proceed on Monday. The notice to proceed allows final design work, right of way acquisition, scheduling and community outreach to begin.

Groundbreaking is anticipated later this year and construction work will continue for four years, with completion expected in mid-2020.
The total cost of the project is about $800 million, which includes the land purchase, preliminary engineering, conceptual designs, environmental studies, and other costs.
The North Perimeter Contractor’s team includes Ferrovial Agroman US Corp., The Louis Berger Group and Neel-Schaffer, Inc.
Over 420,000 vehicles travel through the I-285/Ga. 400 corridor every day. Located at the nexus of two vital freeways and a MARTA rail line, the interchange serves one of the Atlanta region’s largest employment areas at Perimeter Center and is a major connection point for freight distribution.
Along I-285, there will be four miles of improvements beginning a mile west of Roswell Road and ending just east of Ashford Dunwoody Road.
Here's an overview of other aspects of the project:
- Along Ga. 400, the project will construct about five miles of improvements from just south of the Glenridge Connector north to the Spalding Drive area
- Construction of a barrier-separated access road along I-285 and Ga. 400 to help reduce weaving, merging, and accelerating/decelerating conflicts
- Reconstruction of the Abernathy Road interchange
- Replacement of the bridge at Mount Vernon Road
- Reconstruction of existing ramps and bridges in the interchange area
- New flyover bridges
- New connections to I-285 and existing interchanges
