# List of Interstate Highways in Georgia

The Interstate Highways in Georgia comprise seven current primary Interstate Highways and eight auxiliary Interstates. In addition, two primary Interstates are currently under proposal, and three auxiliary Interstates were once proposed and then cancelled. Each Interstate has a hidden state route number; for example, Interstate 75 (I-75) is also State Route 401 (SR 401) and Interstate 16 (I-16) is also State Route 404 (SR 404, the Jim Gillis Historic Savannah Parkway). This highway system uses the Georgia Peach Pass for toll lanes.
