The Georgia Department of Transportation will conduct three public hearings next week on its plan to reconstruct the interchange of I-285 and Ga. 400, which Gov. Nathan Deal identifiedas a priority transportation infrastructure improvement project.

The proposed improvements include:

  • Construction of barrier-separated collector-distributor lanes along I-285 and Ga. 400
  • Reconstruction of existing ramps between the two
  • Building new flyover bridges and reconstructing and widening existing bridges in the interchange area
  • Construction of grade-separated, braided ramps (where one ramp crosses over another) in the vicinity of Ashford Dunwoody Road and Roswell Road to eliminate conflicts between traffic entering and exiting GA 400 and traffic entering and exiting the Roswell Road and Ashford Dunwoody interchanges.

On I-285, the project would begin west of Roswell Road and extend to east of Ashford Dunwoody, about 4.3 miles. On Ga. 400, the project would begin just south of the Glenridge Connector and extend north to the Hammond Drive interchange area, where it would tie into an adjacent, separate collector-distributor lanes project. The total length of the proposed improvements on Ga. 400 is about 1.2 miles.

The public hearings will be held from 11 a.m to 1 p.m., Tuesday, Aug. 19, and Thursday, Aug. 21; and 5 to 7 p.m., Thursday, Aug. 21.  The hearings will be held in the gymnasium of the Dunwoody Baptist Church at 1445 Mount Vernon Road, Dunwoody.

Comments will be accepted at the hearing and written statements can be submitted until Sept. 5 to:

Ms. Hiral Patel, P.E.
State Environmental Administrator
Georgia Department of Transportation
600 West Peachtree Street, NW – 16th Floor
