is a long alternate route of US 129 that travels from Hawkinsville to Macon, via Cochran, in the central part of the U.S. state of Georgia.

About 100 feet (30 m) later, they begin to curve to the northeast and travel northwest of the Hawkinsville–Pulaski County Airport.

Later, it crosses a railroad line previously owned by Southern Railway then intersects US 23 Bus./SR 87 Bus.

The vicinity is also the site of the NRHP-listed Cochran Municipal Building and School, and the Bleckley County Courthouse.

Between East Ash Street and East Railroad Avenue, the road curves to the northeast with that same Southern Railway line earlier flanking the west side, although the tracks begin to move away from the road north of unmarked Emergency Route 105.

finally ends at US 129/SR 11/SR 49, but SR 22 continues along US 129 until it breaks away from the route in Gray as it heads towards Comer.

is a 7.1-mile-long (11.4 km) former section of US 129 from Arcade to Jefferson, Georgia that has existed as a business route since 2000.

The highway travels along the west side of a former Seaboard Air Line Railroad (originally Gainesville Midland Railroad) line, and the first intersection that it encounters is SR 82, which immediately joins the concurrency.

Near a liquor store and former gas station now utilized as a fruit stand, US 129 Bus./SR 15 Alt./SR 82 crosses the Arcade–Jefferson city line and the first intersection within the city is former SR 319 (Etheridge Road), and Rambler Inn Road.

The highways descend along a slight grade through a mostly residential area before running along the east side of Woodbine–Jefferson City Cemetery, where it enters the Jefferson Historic District[9] Here, they make a right turn at SR 11 Bus.

Then, they travel along the east side of the same Seaboard Air Line it ran along when US 129 Bus.

Those tracks curve to the west at a private railroad crossing next to a local embroidery shop.

begins at exit 22 on Interstate 985 (I-985)/US 23 when US 129 joins that concurrency after leaving Athens Highway.

Shortly after this, an intersection with Chestnut Street Southeast, which leads to an Amtrak station, then climbs an embankment in order to cross a pair of bridges over the former Atlanta and Charlotte Air Line Railway (later Southern Railway) line east of the Amtrak station.

Upon descending from the bridge, the road intersects Martin Luther King Jr. Boulevard, which spans from Peter Nix Parkway to SR 11 Connector (SR 11 Conn.), and then curves to the northwest at the northern terminus of Athens Avenue, a former section of the highway.

From there, US 129/SR 11/SR 369 travels through the territory of Brenau University, and later passes by the Northeast Georgia Health Systems and Medical Center which is on the northwest corner of SR 11 Conn. More local medical clinics line the road as the highways travel through New Holland, although there are also some schools and the Frances Meadows Aquatic Center, a local swimming pool and water park.

It is completely concurrent with State Route 11 Bypass (SR 11 Byp.)

The bypass routes begin at an intersection with US 129/SR 11 just south of the city limits of Cleveland.

U.S. Route 129 Alternate (US 129 ALT) was a former segment of US 129 that ran from Old Town to Branford, Florida.

It included the Glenn Gooch Bypass from US 19/US 129/SR 11 (Gainesville Highway/Cleveland Street) to US 76/SR 2/SR 515, and along US 76/SR 2/SR 515 to the southwest part of the city.
