The route then travels into Moreland, where it turns slightly northwest, crosses I-85 once more, and heads into Newnan.

There following portions of SR 14 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: SR 14 was established at least as early as 1919 on its current path, from West Point to Atlanta.

Three segments of the highway had a completed hard surface: a portion in the east-northeast part of West Point, from south-southwest of LaGrange to just southwest of the Troup–Meriwether–Coweta county tripoint, and from Moreland to Atlanta.

was an alternate route of SR 14 that existed entirely within the city limits of LaGrange.

Between June 1963 and the beginning of 1966, it was established from US 29/SR 14/SR 109 (Broad Street) east past SR 219 to US 27/SR 1/SR 219 (Hamilton Road; this intersection also served as the western terminus of SR 720) and north on them to US 29/SR 14/SR 219 (Broad Street; this intersection also served as the southern terminus of US 29 Bus./SR 14 Conn.[8][9] Between the beginning of 1974 and the beginning of 1977, the path of US 29/SR 14/SR 109 in the western part of the city was shifted southward, replacing the path of SR 14 Alt.

The former path was redesignated as SR 14 Conn.[13][14] The entire route is in LaGrange, Troup County.

Then, it reaches SR 109 (Lafayette Parkway) just over 1 mile (1.6 km) before meeting its northern terminus, an intersection with US 29/SR 14 (Hogansville Road).

is a 13.7-mile-long (22.0 km) alternate route of SR 14 that exists entirely within the southern and southeastern parts of Fulton County.

It connects Palmetto with Red Oak, located southwest of Atlanta.

The three highways travel north on a nearly due-north direction, until they reach SR 70 (South Fulton Parkway).

The concurrency heads northeast, passing Cedar Grove Lake, and intersects SR 92 (Campbellton–Fairburn Road).

They pass South Wind Golf Course and curve to a nearly due-east direction.

Here, both US 29 Alternate/SR 14 Alternate meet their northern terminus, and the roadway continues as SR 14 Conn.[20] All of SR 14 Alt., from the eastern end of the SR 154 concurrency to its eastern terminus, is included as part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.

Then, it headed in an easterly direction to Interstate 85 (I-85) and north-northwest to US 29/SR 14 east of Red Oak.

Its western terminus is at an interchange with US 29/SR 14 (Roosevelt Highway) in Red Oak, where the roadway continues as US 29 Alt./SR 14 Alt.
