State Route 70 (SR 70) is an 8.29adj=midNaNadj=mid state highway entirely within southern Shelby County in the north-central part of the U.S. state of Alabama. The western terminus of the highway is at an intersection with U.S. Route 31 (US 31), just north of Calera. The eastern terminus of the highway is at an intersection with SR 25 in Columbiana. West of the western terminus, the roadway continues as Shelby County Road 22. The interchange of US 31 with Interstate 65 (I-65) at exit 231 is less than 1miles from the intersection of US 31 with SR 70.

Until the mid-1990s, SR 70 between Columbiana and Calera traveled through a mostly rural area of the county.
