Interstate 985 Georgia


Interstate 985 both acts as a commuter freeway joining the Atlanta metropolitan area with Lake Lanier and the city of Gainesville and a part of a long distance route for U.S. 23 to the north Georgia mountains. Although still rural in appearance, suburban growth adds traffic to the route with some sections more urbanized in design. 70 mile per hour speed limits are posted throughout the 24-mile route.

All of Interstate 985 doubles as both Georgia 365 and unsigned Georgia 419. U.S. 23 accompanies the route from Exit 4 northeast to the Interstate end at U.S. 129 on the east side of Gainesville. U.S. 23 extends northeast from there as an expressway toward Clarkesville and Toccoa.

Planned Improvements

Construction to extend the I-85 Express Lanes northeast from Old Peachtree Road to Hamilton Mill Road involves the addition of new ramps to and from Interstate 985. These will provide direct connections to the HOT lanes from I-985. The two-year, $140-million project concludes in 2018

A new diamond interchange will be constructed on Interstate 985 with H.F. Reed Industrial Parkway between Exits 12 and 16. The project will extend H.F. Reed Industrial Parkway south from parallel Thurman Tanner Parkway across I-985 & U.S. 23 to the intersection of Georgia 13 and Martin Road. No timetable has been set as of fall 2015.


I-985 was approved as an Interstate Highway by AASHTO on December 7, 1984. The freeway was previously constructed between August 1962 and December 1969 as a new alignment for U.S. 23.1

According to Steve Williams, until 1985 the freeway was simply known as Georgia 365, despite the merge of U.S. 23 from the first exit (Georgia 20 - former Exit 1). Once the limited access portion ends in Gainesville, the highway is signed as U.S. 23 & Georgia 365 to Cornelia. GA 365 eventually splits north of Cornelia, joining GA 17 and U.S. 123 as it goes through Toccoa en route to the South Carolina line. Locals started referring to the limited access portion as "985" once it was signed accordingly.

$74.6-million in construction at Oakwood included the construction of a new interchange (Exit 17) with Georgia 13 (Atlanta Highway) and the addition of collector distributor roadways between it and adjacent Exit 16 with Georgia 53 (Mundy Mill Road). The work was completed between June 8, 2006 and July 31, 2009.2

Historical Perspective from U.S. 23 & Georgia 365 south
Older guide signs for Exit 24 from U.S. 23 & Georgia 365 south also referenced U.S. 129 Business instead of the U.S. 129 mainline previously.

Aerial showing the wye interchange between Interstate 985 and Interstate 85 east of Suwanee, Georgia
The interchange between Interstate 985 and Interstate 85 is surrounded by several large-scale subdivisions to the east and west while the industrial section of Suwanee borders the wye interchange to the south. The Mall of Georgia can be accessed by both interstates; Interstate 985 via Exit 4 (U.S. 23 and Georgia 20) and Interstate 85 via Exit 115 (Georgia 20 - Buford Drive).
The I-985 freeway initially opened north to Georgia 20 (Buford Drive). The remainder opened in 1969 as Georgia 365.
The north end of the Georgia 365 freeway tied into Old Cornelia Highway, which was then both U.S. 23 and Georgia 13. Old Corelia Highway east from Gainesville today is unnumbered through to Georgia 52, which remains along the route north toward Lula.
