Just two blocks later the wrong-way concurrency with SR 135 Bypass ends when that route makes a left turn onto Oak Street going south.

Just after the routes cross the Lanier-Berrien County Line, they intersect Johnson Street Extension, and Myers Road, then runs through the forestland surrounding Beaverdam Creek before eventually entering Ray City, where it becomes Main Street, curves almost straight west, and serves as the southwestern terminus of Georgia State Route 64.

Two blocks later at the NRHP-listed Berrien County Courthouse, the concurrency with Georgia State Route 76 comes to an end as it turns east onto East Marion Avenue, while at the same intersection the concurrency with Georgia State Route 125 comes to an end as it turns west onto West Marion Avenue.

The road passes by the post office, then the Alapaha Baptist Church, and three blocks later, turns left at US 82/SR 520 (South Georgia Parkway).

The concurrency leaves the town limits, and after a local farm supply store, US 129/SR 11 branches off to the northwest onto Alapaha Highway, while US 82 heads west to Albany, Georgetown, Montgomery, Alabama, and ultimately Alamogordo, New Mexico.

Meanwhile, US 129/SR 11 passes by some local farmland along with a dirt road, then after a cemetery enters some wetlands where it makes a slight curve to another northwest angle passing by a fish farm,[3] then curves to the right before the intersection with Berrien County Road 246, then crosses the Captain Henry Will Jones Bridge over the Alapaha River and turns back to the northeast again.

US 129/SR 11 curves slightly to the northeast before passing by the Irwin County Detention Center, then crosses a bridge over Stump Creek, and becoming Irwin Avenue as it turns straight north before approaching the intersection with Five Bridge Road and East Boulevard, the latter of which is where Georgia State Route 90 turns from west to north in a concurrency with US 129/SR 11.

Further downtown, both streets approach Central Avenue, a divided boulevard that provides a link between the northern terminus of Georgia State Route 125 and US 319.

An abandoned former section can be found on the east side of the road as it approaches the intersection with Georgia State Route 112, which joins US 129/SR 11 in a concurrency north of here.

After the intersection with Fire Tower Road US 129/SR 11/SR 112 enters the city limits of Hawkinsville, and instantly passes alongside of the Lawrence Bennett Harness Horse Racing Training track.

The same intersection is also the southern terminus of US 129 Alt., which heads east and US 129 Bus., which continues northbound onto Jackson Street, while the concurrency with SR 112 ends and joins US 129 Alt.

The five highways later travel through Rutland as they pass over a bridge for a former Central of Georgia Railway line, and then turn north again where they encounter an interchange with Houston Avenue, a former segment of US 41/SR 11/SR 49.

US 41 Bus./US 129/SR 11/SR 49 continuously curve toward the northeast, traveling close to the same CofG line it crossed over in Rutland until it turns straight north between Estaville Avenue and Greter Street.

Three blocks after this intersection, the road travels under the bridge for SR 22 (Second Street), which only includes access from a south to east loop ramp.

This continues even as it crosses the Bibb-Jones County Line, just north of the intersection with the southern terminus of Old Clinton Road a former segment of SR 11.

The north end of Old Macon Road and an entrance to a gated community called "Landfall at Porter" is where the routes enter Gray.

The reason for the existence of such businesses is due to the parkland and wetland as it approaches the bridge over Big Cedar Creek, where US 129/SR 44 enters Putnam County, and the name of the street changes to Gray Road Southwest.

West of another section of Oconee National Forest the concurrency runs through communities such as Apalachee, Farmington, and Bishop where it encounters the eastern terminus of Georgia State Route 186.

The road curves northwest along some large plot of farmland then northeast in front of a gas station/convenience store and the Attica Sports Complex next door.

After this is an intersection with Panther Drive, which serves the Jackson County High School, and a school bus garage US 129/SR 11 then runs along a pair of bridges over the same former SAL Railroad Line that flanked it since it ran past the golf course in Athens, then intersects Holders Siding Road, which leads to the NRHP-listed Holder Plantation.

The road is currently widened to four lanes before the western terminus of Georgia State Route 323, then curves off to the northwest again, later running through Bailey.

Within Gainesville, US 129 once again joins the concurrency with US 23 at Exit 22 on Interstate 985, which is also shared by the southern terminus of US BUS 129, and SR 11 leaves the overlap to follow the business route downtown.

[14] After the intersection with Georgia State Route 254, and a Shell gas station on the northeast corner, US 129/SR 11 crosses the Hall-White County line.

The route enters the City of Cleveland, just before the intersection with Donald E. Thurmond Parkway,[15] then US 129/SR 11 curves to the northwest just before the southern terminus of the unfinished US Bypass 129, where the existing US 129/SR 11 turns right onto South Main Street.

A runaway truck ramp can be seen just before the entrance to Vogel State Park, which itself ran along the west side of US 19/129/SR 11 since the routes entered Union County.

North of the park, Georgia State Route 180 (Wolf Pen Gap Road) joins this concurrency, where the routes encounter such sites as the Byron Herbert Reece Farm and Heritage Center,[18] a local grocery store[19] and a gift shop diagonally across from where SR 180 leaves the concurrency at Bald Mountain Road.

In Owltown, random trading posts, flea markets and some restaurants are found along the road, one of which uses an oversized chair as a promotional tool.

Evidence that a more urban setting is to come can be found when the routes make a right turn at Glenn Gooch Bypass (doubling as Shoe Factory Road), while the name of the street formerly designated as US 19/129 changes to Cleveland Avenue.

The road turns north again where it utilizes a short causeway over Wellborn Branch, a tributary of the Nottely River before intersecting the northern terminus of Pat Haralson Memorial Drive, and across from this a local marina with a gas station/convenience store, small bait & tackle store and gift shop before the intersection with Pat Colwell Road.

Random current and former boating and automotive-related businesses can be found along the way even as the road enters Canal Lake where another short causeway that makes a pond leading to Stevens Branch Creek, and is served by the Nottely Marina.
