Interstate 575

Interstate 575 (I-575) is an Interstate Highway spur route in the United States, which branches off Interstate 75 in Kennesaw and connects the metro Atlanta area with the north Georgia mountains, extending 30.97 miles (49.84 km). I-575 is also the unsigned State Route 417 and is cosigned as SR 5. I-575 begins in northern Cobb County near Kennesaw and goes mostly through Cherokee County, ending at its northern border with Pickens County, where it continues as SR 515.

It is also the Phillip M. Landrum Memorial Highway in honor of Phillip M. Landrum (1907–1990), who was a U.S. Representative from Georgia.

Route description

For almost all of its length, I-575 has two lanes in each direction, with a road median of grass, along with crepe myrtle (a locally-common landscaping tree) or wildflowers, both of which are summer-flowering. Each direction has one truck lane for climbing uphill (mile 12 to 13 northbound, mile 10 to 9 southbound), two extended acceleration lanes (north from Towne Lake Parkway and south from Marietta Highway), and two auxiliary lanes (connecting Bells Ferry and Chastain Roads).
