U.S. Route 231 is a spur of U.S. Route 31. It currently runs for 912 miles (1,467 km) from St. Johnmarker, Indianamarker at U.S. Route 41 to south of U.S. Route 98 in Downtown Panama Citymarker, Floridamarker.

One of its most notable landmarks is the William H. Natcher Bridge, a nearly mile-long cable-stayed bridge that connects Rockport, Indianamarker to Owensboro, Kentuckymarker, spanning the Ohio River.

Route description

Major cities


In Floridamarker, US 231 is paired with unsigned State Road 75. The southern terminus is at Business US 98 (unsigned State Road 30) in downtown Panama Citymarker. The highway is carried by Harrison Avenue until its intersection with US 98. Continuing north, US 231 passes through Youngstownmarker, Fountainmarker, Alfordmarker, Cottondalemarker, and Campbelltonmarker before entering Alabama. Major intersections include Business US 98, US 98, SR 77, SR 20, Interstate 10, US 90, SR 73, SR 273, and SR 2.


In Alabamamarker, US 231 is paired with unsigned State Route 53 from Huntsville to Dothan. From the Tennessee state line to Huntsville, and from Dothan to the Florida state line, this route is paired with unsigned State Route 1. In Harpersvillemarker US 231 follows US 280 east. Just south of Sylacaugamarker US 231 branches off southward again as its own route to Montgomerymarker.

In Dothan, there is a spur of US 231, Business US 231 which runs north-south directly thru downtown Dothan from US 231 at the Ross Clark Circle. Until the 1980's, there were several other Business US 231 designations near and thru the towns of Brundidge, Troy, and Montgomery.

Also, until the 1980's, there was an Alternate US-231 which ran north from the intersection/interchange with US-280 just south of Sylacauga, Alabama northeastward thru Sylacauga, Winterboro, and onto Talladega, Alabama. This routing was co-signed with Alabama State Route 21. From Talladega, Alternate US-231 ran northward co-signed with Alabama State Route 77 to just south of Lincoln, Alabama. There for a one mile segment, Alternate US 231 ran along its own route just west of and parallel to Alabama State Route 77 until it reached an intersection with US-78 in the center of the small town of Lincoln, Alabama. There Alternate US-231 turned westward for nine miles co-signed with US-78 into Pell City, Alabama. There Alternate US-231 rejoined US-231. Alternate US-231 was decommissioned in the early 1980's.

Much of US 231 throughout north and central Alabama is a two lane route. However, from just north of Wetumpka, Alabama southward to the Florida state line the route is four laned. In north and central Alabama, US 231 traverses the SW to NE ridgelines of the Appalachian Mountains as well as crossing several river valleys which provide some excellent natural scenery. Most of the four lane segment south of Wetumpka, Alabama to the Florida state line is along gently rolling countryside from several river and stream valleys onto the Gulf Coastal Plain.


US 231 pairs with 31E and continues to run south through the eastern Nashville metro area through the cities of Lebanon and Murfreesboro, and finally reaching Fayetteville until it crosses the Alabama state line. The route is approximately from Tennessee's northern border to its southern border.


US 231 parallels Interstate 65 before reaching Bowling Greenmarker. From Bowling Green, US 231 closely parallels the William H. Natcher Parkway until it reaches Owensboromarker. At Owensboro, US 231 joins the US 60 By-pass (also known as the Wendell H. Ford Expressway) around the city's east side to US 60, which it then follows to just north of Maceo. US 60 then leaves toward the east while US 231 turns to the north, leaving the state via the William H. Natcher Bridge across the Ohio River.

Future plans

As of 2008, the Wendell H. Ford Expressway ends at a signalized intersection with US 60. The Kentucky Transportation Cabinet has plans to extend the expressway from the Kentucky 54 interchange northeastward to the present at-grade intersection of US 60/US 231 and Kentucky 2830. This project was originally to have been completed in 2010, although it has been delayed indefinitely due to budget concerns at the state level.


In Indianamarker, US 231 has the distinction of being the state's longest continuous highway. It covers approximately in the Hoosier State. US 231 passes through the towns of Dale, Huntingburg, Jasper, and Loogooteemarker before reaching Bloomfield. In Bloomfieldmarker, US 231 passes Shawnee Fieldmarker, a local airport. US 231 slices through central Indiana before reaching Lafayette, where it runs just south of Purdue Universitymarker. Next it winds northwest along Interstate 65 and then it splits off and terminates at US 41.

Modernization in Southern Indiana

Indiana's Major Moves program, which derives its funding from the lease of the Indiana Toll Road to private interests, has made it possible for the state to build many new miles of roadway throughout the state. As part of this program, US 231 is currently being updated to a new-terrain four-lane highway from the Indiana-Kentucky border through Spencer Countymarker to Interstate 64. This segment of US 231 has been named the Abraham Lincoln Memorial Parkway.

As of September, 2008, the Lincoln Parkway is complete from the Kentucky line to Indiana 70 southeast of Chrisneymarker. As of November, 2008, Construction is nearing completion on the interchange at I-64 and the by-pass of Dalemarker at the northernmost end of the project. It is now a fully operational partial cloverleaf and the previous 2 lane 231 Overpass has been demolished. It has been replaced by a new 4 land overpass. Other phases of the project are in various stages of construction.

In addition to the Spencer County project, a four-lane by-pass of the Dubois Countymarker cities of Huntingburgmarker and Jaspermarker is also in the planning stages, with completion tentatively scheduled for 2015.


A US 231 shield used in Florida prior to 1993
U.S. Route 152 was commissioned in 1934, connecting Indianapolismarker with Hammondmarker. It followed US 52 from Indianapolis to northwest of Lafayettemarker, where it turned north to end at US 20 in Hammondmarker. In 1938, the route was decommissioned, and became a southern extension of State Road 53 from northwest of Lafayette to Crown Pointmarker, a new State Road 152 from Highlandmarker to Hammond, and was simply dropped in favor of the overlap US 52, State Road 8, and US 41 elsewhere. These parts of SR 53 and SR 8 became US 231 in 1952, when US 231 was extended north from Montgomerymarker to US 41 south of St. Johnmarker.
