Georgia State Route 54

State Route 54 (SR 54) is a 70.5 mi state highway that travels southwest-to-northeast through portions of Troup, Meriwether, Coweta, Fayette, Clayton, and Fulton counties in the northwestern part of the U.S. state of Georgia. The highway connects Hogansville with Atlanta, via Peachtree City, Fayetteville, Jonesboro, and Forest Park.

Route description
SR 54 begins at an intersection with US 27/SR 1 (New Franklin Road) west of Hogansville, in north-central Troup County. It heads east into town, where it intersects US 29/SR 14/SR 100 (Hogansville Road). SR 54/SR 100 head to the southeast concurrently. Just before leaving the county, the highway has an interchange with Interstate 85 (I-85). Then, the two highways split before crossing into Meriwether County. SR 54 heads east-northeast, and curves to the northeast, until it enters Luthersville. There, it intersects US 27 Alternate/SR 41 (Roosevelt Highway), before meeting the northern terminus of SR 54 Spur (Park Street). At this intersection, SR 54 turns to the north and crosses into Coweta County. It heads northeast, through rural areas of the county and intersects SR 16 in Turin. Almost immediately after, it enters Sharpsburg, where it meets the southern terminus of SR 154 (Sharpsburg McCollum Road). Northeast of Sharpsburg, SR 54 has an intersection with SR 34 (Col. Joe M. Jackson Medal of Honor Highway). The highway heads to the east, crossing over Line Creek into Fayette County and Peachtree City. It curves to the northeast and intersects SR 74 (Joel Cowan Parkway). SR 54 curves to the east into Fayetteville, where it intersects SR 85/SR 92 (Glynn Street). To the northeast, it passes McCurry Park North and Links Golf Club, before crossing into Clayton County. In Jonesboro, it intersects US 19/US 41/SR 3 (Tara Boulevard). The four highways head concurrent to the north, along the western edge of Jonesboro. Just before the concurrency ends, they intersect SR 138 Spur (North Avenue). Slightly farther to the north-northwest is an intersection with SR 138. At this intersection, SR 54/SR 138 head east, just north of the city limits. At Jonesboro Road, SR 54 splits off to the north-northeast and enters Morrow. There, it passes Southlake Mall and has an interchange with I-75. Slightly south of the northern limits of town, it passes Clayton State University and curves to the north-northwest into Lake City. There, it meets the eastern terminus of SR 331 (Forest Parkway). In Forest Park, the highway skirts along the southwestern edge of Fort Gillem and meets the southern terminus of SR 54 Conn. (Thurman Road). SR 54 enters Fulton County, and thus Atlanta, approximately 2000 ft before it has an interchange with I-285. It passes Southside Park, the largest part in the city, before curving to the north-northeast and passing Browns Mill Golf Course. After that, it curves back to the northwest and passes Southview Cemetery, just before meeting the southern terminus of SR 54 Conn. (Sawtell Avenue SE). Less than 1 mi later, it meets the western terminus of SR 42 Spur (McDonough Boulevard SE). Approximately 1000 ft later, it turns to the southwest. Then, it curves back to the northwest to meet its northern terminus, an interchange with I-75/I-85 (Downtown Connector) in Downtown Atlanta.

The only portion of SR 54 that is part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense, is from SR 34, west of Peachtree City, to the northern end of the SR 138 concurrency, on the northern edge of the city limits of Jonesboro.
