Travel directions

Interstate 575 branches off Interstate 75 north of Atlanta. Between the major suburbs of Marietta and Kennesaw, I-575 begins at I-75 and heads north in 2×2 lanes. I-575 initially has an alternate lane to Woodstock. After that, I-575 has 2×2 lanes. The road leads through densely wooded suburbs that gradually turn into more rural areas. A historic center on the route is Canton. To the north of this the terrain becomes hilly. I-575 becomes State Route 5 at Nelson and continues through the Appalachian Mountains.

History

Before the construction of I-575, State Route 5 was the through route, but was somewhat less important than US 19 and US 441, which also form north-south routes from Atlanta to the Appalachian Mountains.

I-575 forms the southernmost portion of Corridor A of the Appalachian Development Highway System. This is a 2×2 divided highway through the Appalachian Mountains, where it was decided to build the southernmost part closer to Atlanta as the Interstate Highway. I-575 is therefore also somewhat newer than most other Interstate Highways in Georgia. The highway was opened to traffic in three phases between 1980 and 1985.

The growth of the northern suburbs followed faster than expected. Beginning in the 2000s, regular congestion on I-575 began to occur, particularly on the southern portion near Kennesaw. The Northwest Corridor, a set of toll interchange lanes along I-75 and I-575, was constructed between 2014 and 2018. The section along I-575 is located in the median strip and is a 1-lane interchangeable lane for which a toll has to be paid. The toll lane has been built up to the bridge over the Little River between Woodstock and Lebanon. The interchangeable lane opened to traffic on September 8, 2018.
