PCIDs Improvement Projects

The Perimeter Community Improvement Districts (PCIDs), representing both the Central (DeKalb) and Fulton Perimeter CIDs, are self-taxing districts that use additional property taxes to help accelerate needed transportation and infrastructure improvement projects.

The PCIDs are leading the charge to implement vital transportation enhancements coupled with land use and zoning strategies that will enhance mobility and improve access to the Perimeter activity center.

Through the PCIDs organization, commercial property owners voluntarily pay additional property taxes for transportation and infrastructure improvements.

Overview of Improvements:

  • Along I-285, approximately 4-miles of improvements beginning 1-mile west of Roswell Road and ending just east of Ashford Dunwoody Road
  • Along SR 400, the project will construct about 5-miles of improvements from just south of the Glenridge Connector north to the Spalding Drive area

  • 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
