SR 67 begins at the entrance to the
3M plant along State Docks Road; this is also the end of state maintenance of the road; new reassurance markers were added to mark this new terminus in early 2019. Past this point, the road continues as a road servicing several important power plants in northern Decatur. After a half-mile concurrency between The Beltline and State Docks Road with SR 20 and U.S. 72 Alternate—both State Docks Road and The Beltline carry SR-67's name—the route turns south onto
The Beltline. This junction is often believed to be the northern terminus of the route. The mile-long stretch between here and
SR 24 carries on the
Corridor V name. It loses the name at the
Parclo interchange with SR 24. The route continues south as
The Beltline. It passes by a Martin's—a clothing chain known also known as Wakefield's in
Oxford; this chain has stores only in Alabama—and continues southeast to the
Decatur Mall. It continues east across a railroad bridge to
U.S. 31. The majority of this stretch is four-laned to six-laned. It continues southeast to
Priceville, where it passes by a
Publix supermarket—the second one along the route—and continues to another strip of restaurants and gas stations, junctioning with
I-65—where it loses The Beltline name and continues to a
FoodLand supermarket. About half of a mile later, the route loses two lanes and climbs up a hill and exits Priceville a few miles later. The route continues for about five miles to
Somerville. It then passes by a post office and then continues onward to another part of Somerville—referred to by some as
Pence—where it passes by a
Jack's fast-food restaurant and junctions with
SR 36. Immediately after this junction is mile marker 24. The route continues for about four miles to
Brewer, just north of
Eva. it continues onward through slightly hilly terrain until it gains a lane southbound and climbs up another hill into
Hulaco. It eventually crosses into
Cullman County. It then junctions with
SR 69 in
Baileyton. It passes through hilly terrain to the
Blount County line. It then continues south and gradually turns east again and junctions with
U.S. 231, almost directly above U.S. 231's junction with
US 278. This is SR 67's southern terminus. ==Future==
