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 north Decatur. After a half-mile concurrency between The Beltline and State Docks Road with SR-20 and US-72 Alt.—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 store chain is only in Alabama—and continues southeast to the Decatur Mall. It continues east across a railroad bridge to US 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 continuing 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 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 US 231 almost directly above its US 231's junction with US 278. This is SR 67's southern terminus.
Future
Over time, The Beltline currently has its own traffic problem and provided ample space for large businesses with interest in Decatur. Plans are underway to widen The Beltline from its current size of four lanes to six lanes to help move traffic along more smoothly. One of the businesses that has contributed to congestion is the Decatur Mall, the only mall in the Decatur metropolitan area.
