johnson ferry road — often incorrectly referred to as "johnson's ferry road," as most other local historic ferry names end in -s or -'s — is now a major arterial road between cobb county and sandy springs. it begins in chamblee at georgia 141 and travels northwest, and temporarily terminates in sandy springs just south of i-285 at an intersection with glenridge drive. then it returns just north of i-285, also at glenridge drive, crossing north/south roswell road (georgia 9 from atlanta) (hammond being the original name of sandy springs) near its central business district. it becomes four lanes at abernathy road, although traffic to and from the northwest generally takes abernathy rather than the southern leg of johnson ferry road. it continues northwest with various turn lanes and descends to riverside drive, then crosses the river, leaving the city of sandy springs and crossing the county line from fulton into cobb.
