It parallels I-65, traveling through Millbrook, Elmore, and Deatsville.

## History

Prior to the 1957 renumbering, SR 143 was numbered State Route 45; it was renumbered because of US 45.

Prior to the construction of I-65, SR 143 crossed the Alabama River on the Tyler–Goodwyn Bridge and entered Montgomery on Parallel Street. The bridge, scene of the murder of Willie Edwards, was subsequently removed.
