Route description

View north from the south end of SR 21

A sign denoting Alabama State Route 21, located in Talladega.

Starting at the northern terminus of Florida State Road 97 at the Florida state line south of Atmore, the route travels north through Atmore, passing under an intersection with Interstate 65 at exit 57, then enters Monroe County and travels northeast through Frisco City and Monroeville and is concurrent with SR 47 for part of this section. SR 21 then once again becomes a standalone route passing through Beatrice and Oak Hill. In Lowndes County, SR 21 begins its first concurrency with US 80, and the two highways enter Montgomery, the state capital, from the southwest. SR 21 then diverges northeastward from US 80 for a short concurrency with US 31, then travels concurrently with US 80 once again (as well as US 82) around the Montgomery city center, diverging from US 82 at US 231 and traveling concurrently with US 231 northward to Sylacauga at an interchange with US 280. From Sylacauga, SR 21 turns northeastward toward Talladega. The route travels close to the Talladega National Forest and the Talladega Superspeedway. From here, SR 21 continues generally northeastward through the cities of Oxford, Anniston, and Jacksonville before terminating at an intersection with U.S. Highway 278 in Piedmont. The route is paved throughout and often multi-lane.
