Georgia State Route 1E (SR 1E) was a route in Floyd County extending along present-day Old Cedartown Road and Maple Avenue from US 27 to the Rome Connector (also US 27). Originally part of US 27, it was originally designated as SR 1 before being reassigned as SR 1E in 1954. US 27 had been relocated along SR 1 Spur, which is present-day US 27 from Old Cedartown Road to present-day US 411 in 1938 with the old route remaining as SR 1 through Lindale. When US 27 was upgraded and relocated in the 1968 to the Rome Connector, SR 1E was truncated to end at the present-day interchange of Maple Avenue instead of extending north to end at SR 101. Essentially a business route for an unincorporated town south of Rome, the state no longer saw the value in retaining an old alignment and transferred control to Floyd County in 1985.
Georgia State Route 3E (SR 3E) mostly traveled concurrent with US 41 from Marietta to Atlanta. It had one short-lived and unsigned banner route, SR 3E Spur which included the Canton Road Connector from I-75 to US 41 (present-day SR 5). It was reverted to SR 3 in 1985 when the former alignment along Atlanta Road was decommissioned.
State Route 9E (SR 9E) was originally constructed early in 1941. In July 1981, as the extension of SR 400 had reached SR 60 in Dahlonega, this designation was removed.
The routing that was followed by SR 9E starts where Hopewell Road splits from the current SR 9 north of Coal Mountain in Forsyth County, and parallels SR 400 very closely. The road changes names to Lumpkin Campground Road as it crosses into Dawson County, passes by the North Georgia Premium Outlet Mall, then crosses SR 53 and SR 400 in rapid succession. Just before intersecting with SR 136 the road changes names again to Harmony Church Road, then is called Auraria Road as it becomes SR 136. The road crosses SR 400 once more to its west, parts ways with SR 136, then travels north through the community of Auraria into Lumpkin County to its northern terminus at SR 9/SR 52 west of Dahlonega.
State Route 56 Spur, being mostly in a rural area, sees an Average Annual Daily Traffic of 5,000 vehicles or less over much of the route. However, the route sees an AADT of 14,300 vehicles near its northern terminus in Augusta.
State Route 131 (SR 131) was a state route located entirely in McIntosh County in the coastal part of the state. Established as a highway number in 1936, the first routing followed present-day SR 99 east of US 17 from Darien to the present-day terminus of SR 57. It was moved to Harris Neck Road east of US 17 as a fully paved route in 1944 and extended along Jones Road in 1948 via a brief concurrency with US 17. When the route was extended along Jones Road, it became a double spur with both sections extending off of US 17/SR 25. This was the only such instance of a highway in Georgia where neither of the two endpoints terminated at a state highway. The western leg of SR 131 extended to the Jones community along present-day Jones Road continuing as a county road beyond the western end. The eastern portion (Harris Neck Road) extended to Harris Neck National Wildlife Refuge. The western leg was the first to be decommissioned, turned to the county in 1977. The eastern leg lasted longer, most likely held back to obtain funding for a couple bridge replacement projects, until 1989.
State Route 134 (SR 134) was a state route located in Telfair and Wheeler Counties. It began at SR 149 and ended at SR 19. The western leg of the route is now Tom Haley Road from SR 149 to US 23. The eastern leg is an unnamed road (CR 197 in Wheeler County) through the Towns community. The former highway included an overlap with US 23.
The original 1937 section is the eastern leg of the route through Towns. The western leg on Tom Haley Rd was added in 1949. Originally designated in both parts as an unpaved road, the entire highway was not fully paved until 1962 with the western leg the last to be paved. Both sections were turned over to county maintenance in 1982.
The designation of State Route 143 (SR 143) was initially used for a 18.8-mile-long (30.3 km) stretch of what is today signed as SR 136 and SR 136 Connector, from an intersection with SR 2 east of LaFayette to Georgia. By 1941, an additional portion of SR 143 had been graded, traveling from SR 53 east of Fairmount to SR 5 (today SR 53 Business) in Tate. With exception to the portion of the portion from east of Henderson Mountain Road to Tate and the portion west of Calhoun, this section ran concurrent with other routes. The portion from Calhoun to Henderson Mountain Road ran concurrent with SR 53 while the portion along Henderson Mountain Road ran concurrent with SR 156. The Henderson Mountain Road portion in Pickens County was mostly unpaved and was not upgraded into a fully paved road until around 2003. However, the portions constructed by the county are substandard and are still not suitable for state highway traffic. Around 2003, discussion took place to reopen the road project to relocate this road but it was tabled due to lack of funding. The only paved section of Henderson Mountain Road that remained on the state highway system past 1973 was the portion west of Jerusalem Church Road.
It should be noted that Henderson Mountain Road was not the original route for SR 143/156 when it was first designated. The route actually followed an entirely different route along Quarry Road and Pleasant Union Road, but that portion was closed and removed from the highway system. In 1958, the route reappeared on its best known alignment along Henderson Mountain Road between Quarry Road and Pleasant Union Road. The original route is still intact today, but it is only used by workers who manage the quarry or tree farm. It is not open to the public except for a portion of Quarry Road on the western end and the portion along Pleasant Union Road, which remains unpaved.
By 1949, the part west of Calhoun of today's SR 136 and SR 136 Connector from the Alabama state line to Calhoun had all been re-designated as SR 143. It was in 1977 when the portion of the route from the Alabama state line to Calhoun was re-designated as SR 136 while the portion along Henderson Mountain Road from SR 53 east of Fairmount to SR 108 west of Tate as SR 379, which meant the disappearance of the designation of SR 143 in Georgia. The primary portion of SR 143, from the Alabama state line to Calhoun, measured 61.044 miles (98.241 km).
State Route 148 (SR 148) had two different routes during its existence. The first was near Chattanooga and the second was near Macon. Neither remain as state maintained roads today.
THE FIRST ROUTE
The first route was in Walker and Catoosa Counties. It followed what is today Reeds Bridge Road, Boynton Road and LaFayette Street from LaFayette Road (Old US 27) to US 41 in Ringgold. The road was originally a federally-administered road under occupation of parts of Chattanooga until the 1940s and was known originally as Ringgold Road. It was designated as a state route in 1939 after the U.S. ceded control to the counties. In 1949, SR 2 was relocated north along a new route running close to the Tennessee border. This included a route through Ringgold, thus SR 148 was replaced with SR 2 from Ringgold west to U.S. 27. SR 2 was later moved to Battlefield Parkway in 1972, so today the former SR 148 is maintained by the counties.
THE SECOND ROUTE
The second route came forth as one of the first legs constructed of I-75 in rural Georgia. Originally a two-lane concrete road, the road later dubbed "New Forsyth Road" extended from SR 87 north to SR 18 in Forsyth. By 1963, most was upgraded to I-75 and the remainder later re-established as SR 19 Spur from SR 87 to U.S. 41. The new route that replaced SR 148 where it overlapped I-75 was extended west along a formerly county-maintained Pate Road to end at Rivoli Road. It included a partial interchange with I-75, but it never actually connected to U.S. 41 pending the construction of an overpass over the railroad tracks that was never built. Today, all portions that did not become I-75 are county maintained.
State Route 160 (SR 160) was a state route in northern Clayton and southwestern DeKalb counties. Its western terminus was at US 19/US 41 and SR 3 near I-285, from which it proceeded in an east-southeasterly direction through Forest Park for approximately 2.0 miles (3.2 km) to an intersection with SR 54 near Lake City. The route then turned north-northwest, concurrent with SR 54 for about 1.4 miles (2.3 km), then turned northeast for 2.3 miles (3.7 km) before reaching its eastern terminus at US 23/SR 42, again near I-285.
SR 160 was turned back to local maintenance in the mid-1990s, likely due to its proximity to SR 331, which was separated from SR 160 by little more than a set of railroad tracks in Forest Park. The segment between SR 54 and US 23 still survives as SR 54 Connector.
For a time, it was uncertain whether the designation route had in fact been removed in full due to an official Georgia Department of Transportation map of Clayton County dated 2005 continuing to label a portion of the route between SR 54 and the DeKalb County line as SR 160. However, that map was later updated and the label was changed to indicate the route as SR 54 Connector.
State Route 161 (SR 161) was a state route in southern Floyd and northern Polk counties. Its southern terminus was at US 27/SR 1 in Cedartown (now both Business Routes). It proceeded northwest to Cave Spring to an intersection with US 411/SR 53. The route was later redesignated as part of an extended SR 100 and then turned to county maintenance in 1976 when SR 100 was relocated further west along Freezer Locker and Mountain Home Roads. Today is it known mostly as Cedartown-Cave Spring Road.
State Route 170 (SR 170) was a state highway located entirely on top of the Lookout Mountain plateau in Dade and Walker Counties. It formed an alternate route for the original route of SR 157 (today SR 189, also known as Scenic Highway) and began at the present-day intersection of SR 189 and Durham Road. From there, it traveled east on present-day Durham Road then turning north on present-day SR 157 (Hinkle Road). After that, it followed present-day SR 157 back to present-day SR 189 at the current southernmost intersection of SR 157 and 189 in the West Brow community.
Most of former SR 170 was converted to SR 157 with only the Durham Road portion transferred to local control. SR 170 was eliminated as a route when SR 157 was relocated and extended north from its original terminus at SR 136 to Durham Road with SR 157 replacing the rest of SR 170. The northern extension of SR 157 also resulted in the deletion of SR 210 just outside the city of Lookout Mountain.
It should be also noted that the routes on Lookout Mountain changed many times. The original SR 170 included only the Durham Road portion only while SR 157 following its present route along what was SR 170 originally was SR 157. SR 170 was first extended in 1946 when SR 193 was relocated from present-day SR 157 to Chattanooga Valley Road. However, SR 193 did not actually extend to Chattanooga like it does today. Instead, it turned back on Nickajack Road westward to follow part of present-day SR 157 and Lula Lake Road. The result of this change was that SR 170 was extended north along what had been SR 193 to join the partially relocated SR 193. By 1952, SR 193 was completely routed in the valley, Nickajack Road turned to Walker County and SR 170 reached its full length. While that route matches present-day SR 157, it only followed a portion of the old SR 193. It is indeed very confusing and best explained showing the maps themselves.
SR 170 was finally decommissioned in 1975 when SR 157 was rerouted onto its original 1930's route (except for turning onto Hinkle Road instead of Lula Lake Road), Durham Road turned over to county maintenance and SR 189 extended on Scenic Highway where SR 157 was prior.
State Route 176 (SR 176) was a state route in Cobb County. It traveled for about 15 miles (24 km) from US 278 (C.H. James Parkway) in Powder Springs to US 41 (Cobb Parkway) in Acworth. SR 176 was located entirely within Cobb County for most of its existence. The route was also known as Richard Sailors Parkway, New Macland Road, Lost Mountain Road, and Mars Hill Road. Famous landmarks along the former route include Lost Mountain Store, which is now a bank, and McEachern High School, which was once an A&M school. SR 176 was turned over to county maintenance in October 2010.
Throughout its history, SR 176 was relocated several times. Its original routing was in both Cobb and Paulding Counties following portions of Old Dallas Road and Dragstrip Road (today East Paulding Drive) from SR 120 to SR 92 (today Dallas–Acworth Highway) in the New Hope community. In 1942, it was extended to Powder Springs although it is unclear if the original route actually followed present-day Lost Mountain Road and New Macland Road initially or if it actually followed Florence Road. In the late 1950s, the original portion of the highway was also paved and realigned moving the original portion of the route out of Cobb County entirely. In 1969, SR 176 was then relocated from its original Dragstrip Road route to Mars Hill Road with the former Dragstrip Road route initially re-designated as SR 92 Connector and later SR 120 Connector before being turned back to Paulding County maintenance in 1982.
The final 1969-1985 route extended from US 41 near Acworth to US 278 in Powder Springs. In Powder Springs, the highway was moved twice before its final removal from the state highway system. The first relocation occurred in 1985 when US 278 was moved from Powder Springs onto C.H. James Parkway. With SR 176 no longer connecting to US 278, it was then extended south along a concurrency with SR 6 Business to include a portion of Austell–Powder Springs Road (Old US 278) and newly constructed/relocated Westside Road. Westside Road as part of the two highways extended from Old US 278 to C.H. James Parkway in a southward direction. In 2001, Westside Road was closed and dismantled in 2001 when a rail yard was constructed in its path. It was originally built with the hope the area would become economically developed, but this never took place. The highway was briefly relocated further south through Clarkdale along a new road built by the rail company before SR 6 Business was decommissioned shortly after, but the new route was too far out of the way to function as a true business route. When SR 6 Business was decommissioned, SR 176 was relocated to the then recently county-built Richard Sailors Parkway in Powder Springs to connect to US 278: a relocation that lasted for nine years.
All portions of the highway were removed from the state highway system in 2010 to allow Cobb County to fast-track intersection improvements. A reverter agreement was stated that the road would be restored to state control when improvements were completed, but this agreement was not honored by GDOT.
State Route 205 (SR 205) was assigned to Bells Ferry Road in Cherokee County. This route was turned over to county maintenance on March 12, 1985. Though Bells Ferry Road does connect downtown Marietta with Canton, SR 205 began at its intersection with SR 92 in the Oak Grove district of southern Cherokee County. In the mid 1990s, Bells Ferry Road underwent an upgrade to a four-lane urban design roadway. This expansion of Bells Ferry Road, including part of the former SR 205, started at I-575 and ended at South Fork Way, just north of Kellogg Creek Road (Old SR 92). Although the portion south of SR 92 was not part of the original SR 205, the state was contracted to rebuilt the roadway along this entire section.
Most of SR 205 was originally part of SR 92. SR 92 was extended into Cherokee County in late 1940 following a convoluted route that included present-day Kellogg Creek Road, Victoria Road, North Victoria Road, Bells Ferry Road, Bascomb-Carmel Road and Dupree Road from Woodstock to Acworth. SR 205 originally was added in 1948 as a short connector route ending further north terminating at the junction of SR 92 when it followed present-day North Victoria Road just over 6 miles in length. Considering that "205" falls out of sequence with the dates that other routes were designated in the same era, it is hypothesized that the designation was deliberately chosen as a subtle reference to SR 5. SR 205 was first extended in 1950 when Victoria Road was cut off due to Lake Allatoona resulting in SR 92 being moved to present-day Kellogg Creek Road. When SR 92 was relocated again in 1970 to Old Alabama Road, SR 205 was extended further south again to meet the new alignment of SR 92 along what had previously been a portion of SR 92 bringing the road to its longest length at 12 miles. From Bascomb-Carmel Road south to the present-day SR 92 the southernmost section was first added as a relocated SR 92 in 1962 and then became SR 205 in 1970. Thus, SR 205 became a shortcut from Canton to Acworth although less so when Lake Allatoona lengthened the trip after Victoria Road was closed off at Kellogg Creek.
Motorists today use this road to access places such as the Little River Marina area of Lake Allatoona, the Towne Lake planned community, and the similar Bridge Mill community southwest of Canton. The need for SR 205 as a highway was mostly eliminated when I-575 opened especially since SR 205 is a winding route and does not directly connect to Acworth. There are no plans to restore the state designation of 205.
SR 207, today known as Hog Mountain Road, was a short route extending from SR 53 to US 129/US 441/SR 15 northwest of Watkinsville. Serving as a cutoff route for SR 53, the route was transferred to county maintenance in 1985 at the same time as nearby SR 209. Former SR 207 is 2.1 miles long.
State Route 209 (SR 209) was a route in Oconee County extending from US 29/SR 8 (presently county-maintained Atlanta Hwy) to US 78/SR 10. It followed present-day Mars Hill Road and S. Burson Avenue and was decommissioned in 1985. Today, it is impossible to travel the entire route from end-to-end since no crossover exists where the road intersects with SR 316.
State Route 210 (SR 210) was a very short state highway located in Lookout Mountain. It had two routes. The original follows Georgia State Route 157 (Red Riding Hood Trail) from the intersection of Lula Lake Road (Old SR 193) down the eastern side of the plateau to the Tennessee state line (Chattanooga city limits). Around 1956, SR 210 switched places with SR 157 with SR 157 taking over the original SR 210 and SR 210 located on the portion of Scenic Highway north of the present-day junction of Scenic Highway and McFarland Rd (current SR 157/189 junction). In 1978, SR 210 was finally retired in favor of an extended SR 189 that included an overlap with SR 157 from Hinkle Road to McFarland Rd.
Former SR 218, today Lakeview Drive, was a route extending from SR 146 (Cloud Springs Rd) to U.S. 27/SR 1 in Rossville. Its primary purpose was to provide state maintained access to popular Lake Winnipesaukah Amusement Park, which first opened in 1925. It was returned to county maintenance on August 15, 1986 along with portions of SR 2 and SR 349 as part of a mileage swap for the extended Battlefield Parkway.
Former SR 222, today Jesse Cole Road, was a route in Meriwether County extending from SR 173 in the Raleigh community to SR 85E. It was removed from the state highway system after the railroad overpass was rebuilt just west of present-day SR 85.
SR 226 was a short highway added to the state highway system in 1943 originally connecting SR 53 in Hall County to SR 9E in Dawson County. Also known as Nix Bridge Road, the highway was severed in 1957 due to Lake Lanier flooding a significant portion of the highway where it crossed and followed Toto Creek. Since SR 53 had also been relocated due to the lake, the eastern Hall County portion of the route went to the county in 1957. Today that section is split between Nix Bridge Road and Cool Springs Road ending at Old Dawsonville Road. The western portion of the route in Dawson County, however, remained until August 1980 as a spur from SR 9E (today Harmony Church Road) to Nix Bridge Park on Lake Lanier.
Evidence also exists that for a time that SR 226 extended further on the Dawson County side prior to the relocation of SR 136. Until 1967, SR 136 ran further north than it does today crossing Ratliff's Ford following part of Old SR 9E and Henry Grady Highway. When a new bridge and roadway alignment was constructed further south, SR 136 was relocated to where it is today. Maps show a state road connecting to Henry Grady Highway on what is now SR 136, but the number is not indicated. The road in question was either SR 226 or SR 136 Connector.
Former SR 235 was a 2.2 mile loop road from SR 9 in what is now the Buckhead neighborhood of Atlanta, Georgia. Heading South, it pulled off of SR 9 (Roswell Rd.) onto Habersham Rd NW, turning left onto Chatham Rd. NW, following it to Andrews Dr. NW, turning right onto Andrews Dr. NW and following it until rejoining SR 9 (Peachtree Rd). The road first appeared in 1944, and was deleted between 1961 and 1963, when it was converted to a local road. 
Former SR 238, today known as Upper Glass Bridge and Lower Glass Bridge Road is a partially submerged former state route connecting US 29 south of LaGrange to U.S. 431 south of Roanoke, AL. Designated in 1945, the route once had a signature feature: a long covered bridge over the Chattahoochee River built by famed bridge builder and freed slave Horace King. In 1975, the bridge was lost when the area was flooded for West Point Lake. That project also resulted in the closure and submerging of a portion of the road permanently severing the road on each side of the river. The western portion of the route is today only accessible from Alabama while the eastern portion dead ends at the lake. When the roadway was closed, the state transferred the remaining open sections to Troup County with a newly relocated SR 109 replacing all other area routes as access to Roanoke, AL and U.S. 431.
SR 239 was a route extending from SR 48 in Cloudland to Old State Road (former SR 157 in Chattooga and Walker Counties. SR 157 originally followed the route it does today south of SR 136, but in 1944, it was turned southwest along an unpaved road to join DeKalb CR 89 in Alabama along what is today Old State Road connecting SR 136 to Mentone. With the former SR 157 already paved, it was re-designated as SR 239 in 1946. As part of SR 157, Old State Road was never paved and was downgraded to projected mileage in 1973 with routine maintenance transferred to the county. In 1977, projected mileage was removed from Old State Road with the SR 157 designation restored to its pre-1944 routing along SR 239. As a result, the SR 239 designation was retired after 31 years. Old State Road was later paved by Walker and Dade Counties, but it is still unpaved in DeKalb County, AL. The transfer of maintenance was likely partially due to the lack of interest in paving the road on the Alabama side and the eventual turnback of state secondary maintenance of CR 89 back to DeKalb County.
State Route 249 (SR 249) was created in 1949 when SR 115 was relocated east of Dahlonega. Prior to 1949, SR 115 used to extend from Gainesville to Dahlonega before turning back eastward overlapping SR 52. The relocation to present-day Old Dahlonega Road shortened this overlap. It is important to note at the time of its creation, SR 60 did not extend south of US 19 at Stonepile Gap. When SR 60 was extended south to Gainesville through Dahlonega in 1956, it replaced the southernmost portion of SR 115 as well as all of SR 249 thus the number was retired.
State Route 258 (SR 258) was a route connecting US 29/SR 14 in Hogansville to US 27/SR 1 passing through the Harrisonville community. It was renumbered as an extension of SR 54 in 1964 when SR 54 was extended west from its former terminus in Luthersville to meet US 29 in Hogansville where it junctioned with SR 258. SR 54 Spur in Luthersville was formed from former SR 54 when its parent route was relocated as part of that extension.
SR 267 was originally formed as a cutoff highway on the southwest side of Geneva connecting SR 41 and US 80/SR 22. Originally unpaved, the route was shortened in 1963 when SR 355 was created to provide new highway access when SR 103 was closed through Fort Benning. SR 355 took over the northern portion of the route, but SR 267 remained for many years after as a relic route east of the SR 355 junction. In 1997, SR 267 was finally returned to county maintenance and is today known as Dr. Brooks Drive. A portion of the original SR 267 was also relocated away from Juniper Lake in 1963 and was re-designated as SR 355 Loop until 1973. Today that roadway is closed to the public.
State Route 287 (SR 287) was a north-south state route located in the west-central part of the state. The route traveled from its southern terminus at the Macon–Taylor county line southeast of Reynolds north to SR 96. This route is currently known as Gen John B. Gordon Road.
State Route 289 (SR 289) was a north-south state route located in the southeastern part of the state. The route traveled from its southern terminus at US 23/SR 19 southeast of Hazlehurst north to US 341/SR 27 in Graham. The route was only partially paved when it was turned back to local authorities in 1979.
SR 294 was a route in Bartow County providing access to Allatoona Dam. The highway was split into two segments providing access to both the top of the dam and the base of the dam. The two segments were officially designated "294N" while the south segment was "294S". However, both were signed simply as 294. The north segment extended from SR 20 just east of I-75 to the top of the dam. The south segment extended from SR 3, now SR 293 north of Emerson to the base of the dam crossing US 41.
In 1977, the south segment was transferred to county maintenance when I-75 was completed. That road is today known as Allatoona Dam Road. I-75 crosses the south segment, but does not provide access. The north segment was redesignated in 1995 as SR 20 Spur with the north route remaining on the state highway system.
Both segments provide access to a number of hiking trails and recreation areas surrounding the dam and Lake Allatoona. Both segments of the road are situated in the Allatoona Mountains. The north segment runs along the east side of Pine Mountain while the south segment runs at the foot of Vineyard Mountain. Cooper Furnace is a notable historic site below the dam, and Bartow Beach is a popular recreation area. Both are accessible from SR 20 Spur/former SR 294N. After 9/11, a portion of SR 20 Spur was permanently closed past the last roadway intersection. This was done for security reasons, but visitors are no longer permitted to drive up to the dam and walk out on the dam like they were prior to 2001. Visitors may only reach the dam today via the former SR 294S.
SR 295 refers to the South Expressway, later I-75 extending from Lakewood Avenue (later rebuilt for the Langford Parkway/SR 166 interchange) to University Avenue (SR 54) in Atlanta. The South Expressway was the first expressway completed in Atlanta originally opening in the late 1940s. It was part of Atlanta's city-built expressway network that was later appended to the interstate system and eventually rebuilt to interstate standards in the 1980s. It was re-designated I-75 when the expressway was extended further north to Georgia Avenue.
State Route 304 (SR 304) was a north-south state route located in Columbia County in the eastern part of the state. From the route's southern terminus at the former routing of SR 47 in Appling, the route traveled north-northeast concurrent with US 221. The route met its northern terminus at SR 150 northeast of Appling. The route is now part of SR 47.
State Route 318 (SR 318) was originally constructed around 1960.
SR 318 was extended and retracted several times before finally being removed around 1985. Originally consisting of only the portion from SR 53 to the boundary of Dawson Forest west of its intersection with SR 9, the road was extended further east in 1963 including an overlap with SR 53 along Warhill Road to end at Warhill Park. A portion of this extension followed what was originally SR 53. The old SR 53 route was closed in portions in 1957 due to the relocation of the route and flooding by Lake Lanier.
What was notable about the Dawson Forest Road section is that it crosses SR 400 and previously 9E. Formerly known as Lockheed Road, the odd routing creating what is technically a road to nowhere was for government and military purposes including the Lockheed nuclear testing area in what is now Dawson Forest. When the facility was shut down, no further need existed for the route with the road today serving primarily as a connector from SR 400 to SR 9.
In 1971, the 1.5 miles (2.4 km) portion of SR 318 west of SR 9 was turned to Dawson County. The Warhill Road portion was removed next on August 20, 1980. The remaining portion from SR 9 to SR 53 was turned to the county on January 18, 1982. However, SR 318 was briefly restored from SR 9 to SR 53 for unknown reasons later that year. It was likely a blowback by Dawson County over the very large number of routes turned back in the 1980-1982 period. The county also had SR 183 restored after losing most of the route that same year. This was short-lived, however, as SR 318 was again returned to the county in 1985.
SR 336 was first designed in 1961 on what is today known as Rock Creek Road in Stephens County. The road was formerly known as Brookhaven Circle until a couple years ago. It extended from SR 17 (now SR 17 Alt) to SR 328 (Gumlog Rd). It was removed from the state highway system on November 29, 1982.
SR 340 was a state route extending from SR 3, present-day Atlanta Road in the Fair Oaks community to US 78 in Austell. The road is best known as Austell Road. At the time, SR 5 followed Powder Springs Road from Marietta to join U.S. 278 in Powder Springs. On June 14, 1983, the state switched SR 5 onto Austell Road and a portion of Atlanta Rd/SR 3 subsequently eliminating the SR 340 designation. Powder Springs Road was partially decommissioned with the portion north of SR 360 reassigned as an extension of SR 360. In 1989, a portion of Austell Road (former SR 340) was returned to county maintenance between South Cobb Drive/SR 280 and Atlanta Road after SR 5 was again relocated onto SR 280 after replacement of the substandard interchange and tunnel was completed at the intersection of the two routes. By that time, SR 3 no longer followed Atlanta Rd negating the need for that portion of Austell Road to remain on the state highway system.
State Route 342 (SR 342) was added to the state highway system in 1961 extending from SR 183 to SR 52 crossing Georgia State Route 136. On January 18, 1982, SR 342 was turned to county maintenance. SR 342 followed what is today Dawson CR 225 under the names Keith Evans Road south of SR 136, which crosses the route and is known as Bailey-Waters Rd north of SR 136. It is today one of the few former routes lost in the early 80's to still retain a vestige of guide signs left over from when the roadway was still a state highway.
State Route 343 (SR 343) was a short-lived state route paired with US 23 and US 441 north of Tallulah Falls existing from 1962 to 1965. At the time, the relocation of U.S. 441 between Tallulah Falls and Clayton had not yet been completed, so SR 15 remained on the old alignment between Tallulah Falls and Wylie with the new alignment designated SR 343. This included not only the existing Historic Old 441 route, but also Terrora Circle. When the new highway was completed, the SR 343 designation was retired and the old US 441 alignment was transferred to the county. However, not all of SR 343 became part of U.S. 441. A small portion between U.S. 441 and Historic Old 441 today is known as Wylie Connector, maintained by Rabun County.
State Route 344 (SR 344) was a state route that was paired with US 411 when U.S. 411 was relocated between Cartersville and Rome in 1962. It ran from U.S. 41 to U.S. 27. At the time, SR 20 remained on the old U.S. 411 alignment through Kingston. On June 16, 1977, SR 20 was relocated to the present-day U.S. 411 route with SR 293 relocated and extended along Old U.S. 411. When SR 20 was relocated, the SR 344 designation was retired.
State Route 346 (SR 346) was a short east-west route located entirely in Jackson County in the northeastern part of the state. From its western terminus at US 129/SR 11 in Talmo, the route traveled east through rural portions of Jackson County until it reached its eastern terminus at SR 82 in Pendergrass. It was turned back to local maintenance in late 2003.
State Route 349 (SR 349) was an east-west route connecting Rossville to the Flintstone community designated along former county roads in 1963. Evidence also exists that the road was originally owned by the federal government during occupation of the area, which ended in the 1940s. Today the road is known as James Street in Rossville and otherwise is known as Happy Valley Road. Its eastern terminus was SR 2, now McFarland Avenue and its western terminus was SR 193, now Chattanooga Valley Road. It was removed from the state highway system on August 15, 1986 when SR 2 was relocated to the newly constructed Battlefield Parkway and SR 193 was relocated to a new alignment east of Flintstone. Battlefield Parkway closely follows the route thus negating the need for the winding two lane road to remain on the state highway system.
State Route 350 (SR 350) was the oldest section of what is today SR 10 Loop forming a portion of the northern leg of the Athens Perimeter. SR 350 extended from U.S. 129/SR 15 (present-day SR 15 Alt) east to US 29/SR 8. When the roadway was completed west to Atlanta Hwy US 29/US 78/SR 8 in 1966, both US 29 and SR 8 were moved onto the road with the SR 350 designation retired. Today both SR 10 Loop and unsigned SR 422 follow the entire length of the Athens Perimeter instead.
SR 351 saw its final days in 1982. However the route signage remained on I-75 until the early 1990s. This route lasted 20 years, originally commissioned in FY 1962-63. Although it no longer exists, many modern maps still show SR 351. It is now known as Jodeco Road in Henry County and Lake Jodeco Road/Charles Q. Carter Highway in Clayton County near Lake Spivey.
State Route 357 (SR 357) was a north-south state route located in Muscogee County in the western part of the state. The southern terminus was at the gate of Fort Benning (previously, the route's southern terminus had been at US 27) on what had prior been SR 1 Spur. From there, the route traveled north along Ft. Benning Blvd, Ft. Benning Road and Brennan Road, all which also were part of SR 1 Spur originally. At that point, SR 357 turned east along Buena Vista Road which had formerly been part of SR 103 prior to the closure of the roadway through the base that year. SR 103 was a major highway, and its closure was highly controversial at the time. Where the roadway met the base, SR 357 turned north on Schatulga Road skirting the western boundary of Fort Benning. Schatulga Road had not previously been a state route. Past the junction with SR 22 Spur (Old US 80) the roadway then continued along Flatrock Road before reaching its northern terminus at US 80/SR 22 in the northeastern portion of the county. The route was turned back to local maintenance in 1982 and is located entirely within the consolidated city of Columbus and Muscogee County.
State Route 359 (SR 359) was a spur route located in Chatham County mostly in the city of Savannah. It began at Broad St (formerUS 17/80) and continued south to terminate at Rio Road along Abercorn Street. It was designated in 1964 and was replaced with SR 204 when the Abercorn Extension was proposed across the marshes to connect Abercorn to I-95. The extension tied Abercorn Street to SR 204 thus why the route was renumbered. The Abercorn Extension was completed in 1972.
State Route 361 (SR 361) was a north-south state route located in Bibb County in the central part of the state. From the route's southern terminus at US 41/US 129/SR 247 south of Macon, SR 361 traveled west, then north, around downtown Macon, to its northern terminus at US 23/SR 87 north of Macon. The route was turned back to local maintenance in 1982.
SR 363 had a banner route, State Route 363 Spur (SR 363 Spur), that traveled along the current alignment of SR 273 and SR 273 Spur west to the Chattahoochee River. The route was turned back to local maintenance in 1982.
State Route 364 (SR 364) was an east-west state route located in Brooks County and Thomas County in the southern part of the state. Its western terminus was in Boston and its eastern terminus was in Quitman. State Route 364 was decommissioned in 1982.
State Route 366 (SR 366) was a north-south state route located in Hart County in the northeastern part of the state. From the route's southern terminus at SR 51 west of Hartwell, SR 366 traveled north, concurrent with SR 77. SR 77 departed to the west, and SR 366 continued north to its northern terminus at I-85, northeast of Lavonia. The route was renumbered as SR 77 in 1990.
State Route 367 (SR 367) was an east-west state route located in Chatham County in the east-central part of the state. The route, which connected to US 80/SR 26 at both ends, traveled along Johnny Mercer Boulevard across Whitemarsh and Wilmington islands. The route, which was renumbered from SR 26 Loop in 1969, was turned back to local maintenance in 1984.
State Route 373 (SR 373) was an east-west state route located in Gordon County in the northwestern part of the state. From the route's western terminus at SR 156 in Calhoun, SR 373 traveled south along Barrett Street before traveling east on Dews Pond Road to the community of Cash, before turning south on Cash Road to its eastern terminus at SR 53 in Sonoraville. The route only existed from 1972 to 1977.
State Route 379 (SR 379) was an east-west state route located in Pickens County in the northern part of the state. From the route's western terminus at SR 53 east of Fairmount the route traveled east-southeast along Henderson Mountain Road from SR 53 to Jerusalem Church Road as a state maintained road and eastward to SR 108 as projected mileage maintained by Pickens County. The route was formed in 1977 on what had previously been portions of the formerly paired SR 143 and SR 156, and was fully turned back to the county on January 20, 1981 when the state canceled plans to complete the reconstruction and realignment of the roadway east of Jerusalem Church Road.
State Route 381 (SR 381) was a north-south state route located in Paulding County in the northwestern part of the state. From the route's southern terminus at US 278/SR 6 in Dallas the route traveled northeast to its northern terminus at SR 92 northeast of New Hope. The route was formed in 1980, after previously being numbered as SR 92 and SR 92 Spur, and was turned back to local authorities in 1992.
On April 4, 1977, Southern Airways Flight 242 attempted a landing on this stretch of highway near New Hope, in Paulding County. The DC-9 crashed, killing the flight crew, 60 passengers, and 8 people on the ground. It also destroyed a gas station, grocery store, and other structures.
While SR 754 was officially a state route, it was neither signed nor maintained by the state. Most temporary state routes are not actually maintained by the state, and they are never signed. GDOT discontinued the use of temporary state route designations in 2015 after 40 years.
The highway designation was assigned in 1986 to replace SR 5 when it was removed from Canton Road, to allow the state to fund improvements to the road. As portions of the project were completed or cancelled, the SR 754 designation was gradually rescinded, finally being removed altogether in 2000 when the very last section was completed from the Cherokee County line to SR 92 in Woodstock.
Canton Road was designated as SR 754 when SR 5 was relocated to I-575 in 1986. This number was assigned to Old SR 5 to facilitate funding for the completion of a previously planned widening project along the two- and three-lane portions of route between the Canton Road Connector (SR 5 Spur) and Sixes Road in Holly Springs. No portion of the route was either signed nor maintained by the Georgia Department of Transportation.
The portion between SR 92 and Sixes Road was decommissioned in the early 1990s when the widening project was canceled, although improvements were constructed on that portion. The remainder was built from south to north and was decommissioned in phases as each portion was completed respectively in 1992, 1995, and 1998. The last portion was completed as an extension of the SR 92 widening project in the city of Woodstock in 2000 between the Woodstock city limits and just north of SR 92. When that last section was completed, SR 754 was decommissioned.
SR 754 is unique in the amount of confusion it caused. Maps continue to show the route 20 years after it first appeared, though it only existed on paper. Part of this is because it was a logical extension of SR 5 Spur, which ends where the Canton Road Connector to I-75 meets the former SR 5 mainline. Locals today continue to call this road "Highway 5" in addition to Canton Road.
