Local Centerline Mileage

In January 2011, GDOT Commissioner Vance Smith sent a letter to all of Georgia’s Elected Officials –159 Counties –531 Municipalities We requested the they report the total local public road centerline mileage (Paved or Unpaved)

This information is needed to comply with State and Federal Law LMIG funds will be distributed to Local Governments based on paved and unpaved centerline miles and population TIA also requires an accurate accounting of centerline miles to calculate funding for each Regional Commission

As of May 3rd, we received reports from – 152 Counties (96%) – 325 Cities (61%) We provide the mileage to Local Grants Office – If local government reported, we provided that mileage – If local government did not report, we provided our recoded mileage

Confirm that your local government has reported its Center Line Mileage to GDOT on the official Reporting Form As a Local Government, you are required within 90 days to inform GDOT when you have: – Acquired / Accepted / Abandoned a road – State Code and
