I-285 & SR 400 Improvements

The proposed improvements are designed to aid in reducing traffic congestion and improve safety in the area surrounding the I-285/SR 400 interchange in metro Atlanta. New flyover ramps, new collector-distributor lanes and other facilities to aid east-west travel on along I-285 and north-south travel along SR 400 would be constructed.

  • I-285/SR 400 Interchange Reconstruction P.I. # 0000784
  • SR 400 Collector-Distributor (CD) Lanes P.I. # 721850-
