Georgia 10 begins in the heart of Atlanta, at a stack interchange at Interstates 75-85 Exit 248D. Following the route of dead Interstate 485 before turning northeast on the Freedom Parkway, Georgia 10 turns east on U.S. 78 to leave the Atlanta metropolitan area. Georgia 10 departs U.S. 78 east of the Stone Mountain Freeway at Snellville, then follows a divided highway on its own east to Athens via Monroe. From Athens east to Augusta, Georgia is cosigned as the underlying state route with U.S. 78.
Perhaps the most prominent section of Georgia 10 is the stub freeway and parkway extending from Interstates 75-85 east toward the Jimmy Carter Presidential Center. Although Georgia 10 is a major traffic collector through downtown Atlanta, it carries an infamous past as part of the controversial and now-cancelled Interstate 485 freeway project through central Atlanta.
Unconstructed Interstate 485
To understand the nature of the Georgia 10/Freedom Parkway boulevard in downtown Atlanta, a little history of the freeway segment is necessary. Georgia 10 is a remnant of a grand proposal to construct an east-west freeway between Interstates 75-85 in downtown Atlanta east to join Interstate 285 (beltway) at Exits 39A-B in Clarkston. This route was never built, but two segments remain from the original freeway proposal: the Georgia 10 boulevard east of Interstates 75-85 and the U.S. 78 Stone Mountain Freeway in Clarkston. AASHTO approved Interstate 485 for the loop on June 30, 1970
The Georgia 10 segment was initially constructed in the 1960s and was to be designated as Interstate 485/Georgia 410 (most Interstates in Georgia have a Georgia 4xx hidden designation). As the freeway construction marched eastward, communities rose in protest to this new corridor cutting through their neighborhoods. The protest reached a fever pitch when construction began during Governor Jimmy Carter's tenure in Georgia. Governor Carter let a construction contract to extend Georgia 410/Interstate 485 east; however, residents protested by chaining themselves to construction equipment associated with the roadwork. This protest resulted in the end of the freeway construction, and Interstate 485 was scuttled. A final administrative change was to renumber the route from Georgia 410 to Georgia 10, thus ending any consideration for this corridor as part of the Interstate Highway System. Remnants of this incomplete construction is still visible today; an embankment for the freeway was constructed near the intersection of U.S. 23/Moreland Avenue and North Avenue.1
Interstate 485 was officially eliminated by AASHTO on June 17, 1975. The only portion of Interstate 485 ever to open to traffic is the stack interchange with Interstates 75-85. Originally signed as Georgia 410, the highway was renumbered to Georgia 10 to coincide with the construction of Freedom Parkway. This at-grade boulevard extends eastward from the exchange with Interstates 75-85 stack to U.S. 29-78-278 (Ponce De Leon Avenue). Georgia 10 then continues east along side U.S. 78 throughout eastern Georgia. Within the Atlanta metropolitan area, Georgia 10 travels Memorial Drive and the Stone Mountain Bypass westward to U.S. 278. The western terminus occurs at the Interstates 75-85 stack interchange.
Interstate 485 was considered as the designation for a total of three separate freeway corridors in metropolitan Atlanta at various intervals. None of these were ever constructed in their entirety. The three corridors considered for Interstate 485 were found in various municipal planning documents. The routing of Interstate 485 changed as a result of the cancellation of Interstate 475 and Interstate 675 through the city of Atlanta and are listed in chronological order:
- Georgia 410 Corridor - from Interstates 75-85 eastward to Interstate 285. The western quarter of the Stone Mountain Freeway (U.S. 78) was included in this particular alignment.
- Western Georgia 410 Corridor Only - from Interstates 75-85 eastward to a never built Interstate 675 extension (planned even earlier as Interstate 475).
- Combination Western Georgia 410/Northern Georgia 400 Corridor - from Interstates 75-85 eastward on an arc to Interstate 85 near the south end of current Georgia Toll 400.
After the third and final permutation of Interstate 485, the aforementioned community opposition resulted in the freeway being downgraded to a parkway between downtown and U.S. 29-78-278 & U.S. 23 (via Georgia Spur 42), and it never was constructed between U.S. 29-78-278 and Interstate 85/Toll Georgia 400.
Georgia 42 Spur - Planned Interstate 485
An eastern branch of Freedom Parkway connects Georgia 10 with U.S. 23 (Moreland Avenue) along the original right-of-way of Georgia 410/Interstate 485. The short connector features a grassy median and footpaths adjacent to one travel lane per direction. The short segment of highway is designated Georgia Spur 42 (Georgia 42 is the counterpart for U.S. 23 in Atlanta).
