Alternate U.S. Route 72 (US 72 Alt.) exists in Alabama on the mostly south side of the Tennessee River between Muscle Shoals and Decatur, while US 72 follows on the north side of the river between Florence and Athens. Alternate 72 crosses the Tennessee River at Decatur, Alabama along with U.S. Highway 31 and follows the entire route of Interstate 565. SR-20 was co-signed with Alt US 72 from Muscle Shoals to Huntsville. SR-20 has since been truncated to the junction of I-65 just east of Decatur.
Originally, Alt US 72 turned off SR-20 on to SR-53 / Jordan Lane in Huntsville and followed it north 1-mile (1.6 km) to rejoin with US 72. With the completion of I-565 in the early 1990s, Alt US 72 was routed along with I-565 to the termination of I-565 at US 72.
Route description[]
US 72 Alt. begins at an intersection with US 43/US 72. Here, this road continues west as part of US 72. East of there, it intersects SR 157 at an at-grade intersection. Here, a concurrency begins.
A few miles east of there, the roads split. SR 157 heads straight towards Moulton. US 72 Alt. turns diagonal at the interchange, heading towards Town Creek and Decatur.
US 72 Alt. enters Decatur after leaving Trinity, carrying SR 20, and serves as the northern terminus for The Beltline(SR 67) and continues eastward towards the town center. After traveling by the Old State Bank, and the in the downtown area, US 72 Alt. has an intersection with US 31 and continues over the "Steamboat Bill" Hudson Memorial Bridge as it and SR 20 continue east towards the interchange with I-65 and I-565, while US 31 continues north towards Athens and Calhoun Community College.
