State Route 21 is a 279-mile (449 km) state highway that extends from Piedmont in Calhoun County to the Florida state line near Atmore in Escambia County. The route runs almost the entire length of the state from the northeast to the southwest. It is the longest signed state route in Alabama.

Route description[edit]

Starting at a junction with SR-9 in Piedmont, the route runs southwest through Jacksonville, Anniston, Talladega and Sylacauga. The route passes close to the Talladega Superspeedway and the Talladega National Forest. After Sylacauga the road is co-routed with U.S. Highway 231 as it heads almost directly south towards the state capital, Montgomery. gives this opinion on the part of the highway through Montgomery:

"Alabama 21 gets lost in the confusion on the Boulevards of Montgomery. Quite a lack of respect for a state route that begins at the Florida state line and does not end until northeast of Anniston."

The highway is co-routed with U.S. Highways 82 and 80 around the Montgomery city center, then diverges southwest of the city. The route proceeds through Oak Hill and Beatrice to Monroeville in Monroe County, and is co-routed with SR-47 for part of this section. The route then runs continued southwest through Frisco City and Atmore to the Florida state border, where the road becomes State Road 97. The route is paved throughout and often multi-lane. Counties traversed by the route include Calhoun, Talladega, Coosa, Elmore, Montgomery, Lowndes, Wilcox, Monroe and Escambia.
