Bell's Ferry Update References: Present-day Bell’s Ferry Road does cross the Little River, however, according to Cherokee County, court documents of 1835, James H. Bell operated a ferry across the Etowah River. It has been suggested that, since James Bell owned Land Lot 252/21/2 at the time and as it contained both banks of the Etowah, this was the probable location of his ferry. This site is near present day BridgeMill community. In June of 1835, Bell sold this property and ferry.  In January 1837, Bell purchased land and a ferry on the Etowah established in 1834 by Jonathan J. Johnson on Land Lot 478/21/2.  Bell operated his ferry there until December 1855 when he sold the property to Samuel Lovinggood who built a bridge across the Etowah near this location. This site is near present day Victoria Landing.
These two Bell's ferry locations account for the Bell's Ferry Rd. between Canton and Marietta, and also for the Bell's Ferry roads found across the Etowah River, running north and west from the LL 478/21/2 ferry site. 
Bells Ferry Road runs from Church Street (former Georgia State Route 3 (SR 3), one block west of former SR 5 on Cherokee Street) in Marietta north to Marietta Street (former SR 5 in Canton). It is an alternative route between the two county seats, departing well west of former SR 5 (which is now renumbered onto Interstate 575). Until 1984, the section of this road from SR 92 at Oak Grove north to Canton was designated as SR 205.
Within the city of Marietta, street name signs use the proper "Bell's" rather than "Bells". However, the southernmost end of the road is called Church Street Extension, despite being a turn off of Church Street, and being a straight continuation of Bells Ferry Road. The counterintuitive name change occurs at an arbitrary place in the road (near Cobb Electric Membership Corporation), instead of at a major intersection like Cobb Parkway. This section was once the main street through the small town of Elizabeth.
See notes above in Bell's Ferry section regarding Bell's Ferry roads in Cherokee and Bartow counties.
Although the name of the road is now Johnson Ferry, the actual ferry that crossed the Chattahoochee River at that point was called "Johnston's Ferry" because it was operated by the landowner there, William Marion Johnston. There is a historical marker placed by the Georgia Historical Commission in 1963 that states, "300 ft. W. stood the res. of Wm. Johnston who operated the ferry in the 1850's, where Johnston's Fy. Rd. crosses the Chattahoochee River. July 5, 1864. Gen. Kenner Garrard's cav. div. [US] en route from Marietta to Roswell via this rd., camped on Willeo Cr., from which point he sent a regiment S. to burn the Paper Mills on Soap Creek. July 9. Newton's 4th A. C. div. [US], moving from Vining's Station, traversed this road to Roswell to support Garrard's passage of the river at Shallow Ford -- retracing July 12 & crossing the river at Power's Ferry, July 13.

Johnson Ferry Road (often incorrectly referred to as "Johnson's Ferry Road") is a major arterial road between Cobb County and Sandy Springs. From Columns Drive on the northwest riverbank of the Chattahoochee River, southeast to Abernathy Road, and continuing east on Abernathy to Roswell Road (SR 9), the roads have been temporarily designated by GDOT as SR 947. This is due to the heavy volume of rush hour traffic traveling this route to get to and from SR 400, and the failure of Cobb and Fulton counties to come to an agreement on their own, with Fulton at one time timing the traffic lights to cause further morning backups into Cobb. While all of the homes along Abernathy will be destroyed for widening, the neighborhoods along the 1.25 miles (2.01 km) of Johnson Ferry Road will be spared. Johnson Ferry and Abernathy will be "broken", such that they flow directly into each other, and will require a turn to stay straight on the original roads. The 1969 bridge at the former ferry location will be widened between Columns Drive on the Cobb riverbank to Riverside Drive on the Fulton riverbank, from its current four lanes to six plus bike lanes, wide sidewalks, and a raised road median. Currently, Johnson Ferry Road is four lanes on the Fulton side (two southeast of Abernathy), and six lanes on the Cobb side (four north of its own Roswell Road, SR 120).
Heard's Ferry, originally Isom's Ferry, was operated by John Heard (1835-1931). Named for Judge John Stevens Heard, served as a corporal in the 9th Georgia Battalion Artillery and buried in the Heard family Cemetery off Heards Ferry Road not far from the ferry location.
This ferry was near Duluth and crossed over the Chattahoochee River. There is currently a street off of Peachtree Industrial Boulevard bearing its name. The ferry is named for Captain Evan P. Howell and the Howell Family.
Isom's Ferry was operated in the 1860s by James Isom. The ferry went by many names, include Isham's Ferry, Isham's Ford, Phillip's Ford, and Cavalry Ford. John Heard took over Isom's Ferry in 1868 and operated it until 1890 as Heard's Ferry.

This ferry was located on the Chattahoochee River between Sandy Springs and Roswell. It is approximately 2 miles west of Holcomb Bridge. There are currently two Nesbit Ferry Roads, one in Sandy Springs and the other in Johns Creek. The Sandy Springs one, located in the Dunwoody Panhandle district, is an exclusive residential area with million dollar homes, some of which have views of the river.
The exact location of the ferry is now the northeastern-most crossing of Interstate 285 over the river; and it is the Fulton-Cobb county line (now the Sandy Springs city limit), with the interstate carrying several lanes of traffic in each direction (just two each way when it opened in 1969). There is a Powers Island in the river at this point, now a hiking area associated with the Chattahoochee River National Recreation Area. Presumably, James Power's ferry was located in the vicinity of this island.
The perimeter highway (I-285) is flanked on its north side by Interstate North Parkway (west) / Riveredge Parkway (east), and on its south side by the ferry's namesake road, each carrying two lanes (one in each direction). Powers Ferry Road runs through Cobb and Fulton counties, terminating at both ends at two different streets named Roswell Road (SR 120 and SR 9, respectively).
The business district just east of the crossing is called Powers Ferry Landing, located where Northside Drive crosses the road, just east of the former landing. This provides freeway access at Northside Drive (west ramps) and New Northside Drive (east ramps, road and ramps built in a 1990s reconstruction). Signage on the freeway indicates Powers Ferry Road, Northside Drive, and New Northside Drive.
Vann's Ferry was the first ferry across the Chattahoochee, starting in 1804. It was named for Cherokee leader James Vann (builder of the Vann House, and crossed the river between Hall and Forsyth counties (both formed later on), at a point now under Lake Lanier. There is no longer a road by this name, and the area is now becoming an exurb of metro Atlanta.
