SR 154 begins at an intersection with SR 54 in Sharpsburg, in Coweta County. It heads northwest and intersects with SR 34 just west of Peachtree City and continues northwest where it has an interchange with Interstate 85 at exit 51. Less than north, SR 154 meets US 29/SR 14 and turns north and runs concurrent with US 29/SR 14 to the northeast. In Palmetto, US 29/SR 14 split to the northeast, while SR 154 heads north, concurrent with US 29 Alternate/SR 14 Alternate through town, until US 29 Alternate/SR 14 Alternate depart to the east-northeast, along South Fulton Parkway. The route continues to the north and intersects SR 70. The two roads begin a concurrency to the northwest. They meet SR 92. The three highways cross the Chattahoochee River, which marks the Coweta–Fulton county line. Then, they intersect SR 166, which joins the concurrency. The four routes head to the northeast concurrently, until SR 92 splits to the northwest and the other three highways heads east to cross over the Chattahoochee River again, and cross back into Fulton County. About later, SR 70 departs to the northeast, while SR 154/SR 166 continue to the east. Just a little bit later, they cross SR 6, entering the Sandtown community on its way to the Ben Hill neighborhood of Atlanta, northeast of which they have an interchange with I-285.
Inside the Perimeter
SR 154/SR 166 head east as the Arthur B. Langford Jr. Parkway, a limited-access freeway that was originally named the Lakewood Freeway and was planned as I-420. It runs along the East Point–Atlanta city line, with a brief cross into East Point proper, before running along the city line again. The Parkway passes Fort McPhersonArmy base. The concurrent routes meets US 29/SR 14/SR 139. SR 154 heads north-northeast into Atlanta proper, concurrent with these three highways. Just before reaching I-20, SR 139 departs to the west, while US 29/SR 14/SR 154 continue to the north-northeast. They cross under, but don't have an interchange with, I-20. After only about, US 29 departs to the northwest, concurrent along Chapel Street SW, along with SR 3 Connector. SR 14/SR 154 heads northeast and cross over, but don't intersect, US 19/US 41/SR 3. At the intersection with Spring Street SW, SR 14 abruptly ends, and SR 154 continues eastward. A short distance later, it crosses over, but doesn't have an interchange with, I-75/I-85. SR 154 parallels I-20 along Memorial Drive SE, intersecting US 23/SR 42, which forms the Fulton–DeKalb county line. Then, it meets SR 155. SR 154 heads northeast to an intersection with US 278/SR 12. It continues to the northeast for about until it meets its eastern terminus, an intersection with SR 10.
The only parts of SR 154 that are part of the NationalHighway System, a system of roadways important to the nation's economy, defense, and mobility, are those parts concurrent with US 29/SR 14 southwest of Palmetto; US 29 Alternate/SR 14 Alternate in, and northeast of, Palmetto; and the Langford Parkway in East Point and Atlanta.
