SR 19 begins at an
intersection with
US 1/
SR 4 north of
Alma. The route travels north,
concurrent with
US 23, which is also concurrent with US 1/SR 4 south of here. Throughout much of this segment, US 23/SR 19 has standard rural Georgia surroundings, with its mix of wooded areas and local farmland. These routes also cross the Bacon-Appling County line before an intersection with Pine Level Church Road, then crosses the
Jeff Davis County Line. North of the intersection with County Farm Road it heads back across the Appling County line, and returns to the Jeff Davis County line at the intersection of Ira Graham/Zora Road. Later they cross a bridge over the
Little Satilla Creek, and after three more intersections with rural dirt roads encounters another bridge over the
Big Satilla Creek and enters the community of
Satilla. No major intersections exist within this community, and very few other paved roads exist. Nearing
Hazlehurst, the routes brushes by a dirt road that used to be an old segment of Alma Highway before the continuing into the southern terminus of
US 23 Bus./
SR 135 Conn., while US 23/SR 19 turns right onto Larry Contos Boulevard, taking part of
US 221 Truck/
SR 135 Truck with it. The first intersection along this segment is that same former Alma Highway section, which is named "Old Alma Road" on the left side, and Davis Street on the right. From there, it passes by a power plant on the west side. The route officially enters the Hazlehurst City Limits between Currie Street and a railroad crossing for a former
Southern Railway line (now the
Norfolk Southern Railway's
Brunswick District). Larry Contos Boulevard ends at
US 341/
SR 27 (a divided four-lane highway Designated the Golden Isles Parkway), and US 23/SR 19 turns northwest along this route. The first notable site along this segment is the combined Hazlehurst Fire Department and the Hazlehurst — Jeff Davis County Chamber of Commerce building on the northeast corner of Oak Street. Two block later, it crosses another railroad line just east of Walnut Street. Two blocks after this, it intersects with northbound
US 221, and the truck routes for US 221/SR 135 officially comes to an end. US 23/US 341 and northbound US 221 travel for one
block until the highways curve to the north at East Coffee (
SR 19 Conn.) and West Jamar Streets, and northbound US 221 finally joins the southbound road once again at North Tallahassee Street, while southbound US 221 continues southbound along South Tallahassee Street. The highways enter
Telfair County by traveling over the Dr. C. R. Youmans Memorial Bridge over the
Ocmulgee River where it enters
Lumber City. SR 19 departs to the north at Victory Boulevard, leaving the US 23/US 341/SR 27 concurrency. From there, it crosses the
Little Ocmulgee River, and begins to parallel the
Oconee River to the north. In
Jordan, SR 19 encounters the eastern termini of both former
SR 134 and still existing
SR 126 merely feet away from one another. In
Glenwood the street name changes to Second Street and intersects
US 280/
SR 30 which is named Second Avenue. North of there, it resumes its rural characteristics and has an intersection with
SR 46 and later the first of many interchanges with
Interstate 16 (I-16), this one specifically at exit 54. In
Dublin, SR 19 briefly travels concurrent with
US 441 then turns west to join
US 80/
SR 26. The three highways travel northwest. In
East Macon, SR 19 becomes concurrent with US 23 again, this time in another concurrency with SR 87. Later, in
Macon, SR 19 leaves US 80/SR 87, and at exit 1A, on I-16 turns south on a wrong-way concurrency with
US 129/
SR 49. After crossing the
Spring Street Bridge over the Ocmulgee River, US 23 turns northwest and US 129 turns southeast at Riverside Drive. Two blocks later, the wrong-way concurrency with SR 49 ends at Walnut Street and is replaced by a concurrency with
US 41 Bus., and then, after a split-diamond interchange with
I-75/
SR 540, joins
US 41. The highways travel north to
Forsyth, where
SR 18 travels concurrent with US 41, and SR 19 meets its northern terminus. The following portions of SR 19, that are concurrent with U.S. Highways, are the only segments that are part of the
National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense: • The segment concurrent with US 23/US 341/SR 27 from Hazlehurst to Lumber City • The segment concurrent with US 80/SR 26 from Dublin to the intersection with US 441 Byp./SR 117 west of the city ==History==
