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 32-4-41 and 32-4-91
