Route description[edit]
Alabama state line to Nashville[edit]
US 431 runs concurrently with US 231 upon entry into Tennessee from Madison County, Alabama, where the concurrency begins. The state line also marks the beginning of a secret concurrency with, and the southern terminus of unsigned State Route 10 (SR 10). The two U.S. Routes plus SR 10 do not split until they reach downtown Fayetteville. While US 231 goes into a north-northeasterly path, US 431 turns northwest into Marshall County, bypassing around Lewisburg, and later into northeastern Maury and into Williamson County. It traverses the city of Franklin, Tennessee before entering the Metropolitan Nashville and Davidson County area.[2][3]
In Nashville, US 431, known as Hillsboro Pike, traverses the exit 3 interchange on I-440, and eventually merges into US 70/SR 1 before entering the downtown area. US 431 then joins US 31 and US 41A onto the James Robertson Parkway. After crossing I-24's exit 47 interchange, US 431 then follows US 41 (SR 11) and US 31W towards the northern suburbs.[2][4]
