East Nashville is an area east of downtown Nashville in Tennessee across the Cumberland River. The area is mostly residential and mixed-use areas with businesses lining the main boulevards. The main thoroughfares are Gallatin Ave and Ellington Parkway, with smaller arteries interconnecting the neighborhoods. Some of these smaller arteries include Main Street, Shelby Avenue, Porter Road, Riverside Drive, Eastland Avenue, McFerrrin Avenue, and Woodland Street in no significant order. Ellington Parkway, which parallels Gallatin Ave and Main Street, bypasses I-24 and I-65 and connects Briley Parkway and downtown Nashville and many other secondary streets along the way. The Cumberland River confines most of the area with a semicircle design on the south, southwest and east. Since East Nashville has no defined boundaries on the west and north the exact perimeter is the cause of some debate. Some would say that Ellington Parkway creates a boundary on the west and northwest, while Cahal Avenue and Porter Road create the northern boundary, in the confines of zipcode 37206. Many would also state that with I-65 and I-24 as the western border and Briley Parkway as the northern boundary, this defines an area that constitutes Greater East Nashville. East Nashville is one of about 26 suburban neighborhoods in Nashville.
