Georgia's Interstate Exit Numbers

New Exit Number Signs

In calendar year 2000, the Georgia Department of Transportation upgraded all interstate exit signs to a new interstate exit numbering system .  The exit numbering system was changed from a sequential exit number system, where numbers move up in a numerical order, to a mile log numbering system, where the exit numbers correspond to mileposts.   This change was implemented to enhance safety along Georgia's roads, allow for cost efficiency and user friendliness, and aid the department in compliance with suggested federal guidelines.

More on Exit Renumbering

  • All signs were upgraded to high-quality, high intensity reflective sheeting signs.  These signs better enhance viewing during the day, as well as at night, when illuminated by headlights.
  • All interstate exit signs were upgraded to "breakaway signs."  These signs bend or flex when hit by motorists, lessening the impact to the motorist and the vehicle.
  • All exit numbers were changed from a sequential numbering system, where numbers moved up in numerical order, to a mile-log numbering system, where the exit numbers correspond to the nearest milepost.
  • The mile-log numbering system allows:
    • Emergency vehicles to get to incidents quicker.
    • More exact times of arrival to an incident to be estimated.
    • Families, police and EMS to locate stranded vehicles quicker.
    • Out-of-town travelers to better estimate travel times.
    • Better travel planning due to more usable distance information.
    • A more efficient way of tracking goods and services by commercial freight vehicles.
  • For East-West interstates, the numbers run from west to east, and for North-South interstates, the numbers run from south to north.  For example, on I-75, the first exit (Exit 2) is near the Florida state line, and on I-20, the first exit (Exit 5) is near the Alabama state line.



Q.  Why did Georgia DOT go to a mile-log system, when I am familiar with the sequential system?

A.  Georgia is one of only two states in the Southeast that is on the sequential system.  Changing to a mile-log system enhanced safety, as it allows emergency response units to quickly find incidents and estimate arrival times on the interstate.  Second, the mile-log system is more cost effective.  Motorists can better plan and estimate total trip costs because of more usable distance information.  Third, the mile-log system brings Georgia into compliance with suggested federal guidelines and on a similar system with other states.  This allows easier transition and quicker understanding of the interstate system for many travelers going state to state.


Q.  Does the non-interstate freeways that are now without exit numbers use the mile-log numbering system?

A.  No.  This change only effects our major interstates.


Q.  Did the exit names change?

A.  No.  The names of the interchanges remained the same; however, the numbers will be different, as they will correspond to the mileage from the state line.


Q.  When did the signs change?

A.  Georgia DOT Contractors completed the exit renumbering project in July 2000.
