quite a few...
Peachtree Street, Peachtree Road, West Peachtree Street, Peachtree Battle, Peachtree-Dunwoody are the ones I can think of off the top of my head.
Here is what I found online:
It is often joked that half of the streets in Atlanta are named Peachtree, and the other half have five names to make up for it. While "Peachtree" alone always refers to this street, there are 71 streets in Atlanta with a variant of "Peachtree" in their name. Some of these include:
Peachtree Creek Road
Peachtree Memorial Drive
New Peachtree Road
North Peachtree Road
Peachtree Park Drive, and
Peachtree Valley Road.
Peachtree Battle Avenue, commemorating the Battle of Peachtree Creek
Peachtree Dunwoody Road, running between Peachtree Street and Dunwoody, Georgia, and
Old Peachtree Road, which traces part of the route of the original Peachtree Trail for which the road is named.
