to six lanes and an exit lane, which is carried along its concurrency with US 72. About a mile north of the second junction with US 72, the route loses its frontage roads and reverts to a four-lane divided highway. In general, the route is an important connector between Dothan, Montgomery, and Huntsville, three of the most populous cities in the state. Tennessee US 231 enters Tennessee from Alabama in a concurrency with US 431 until it reaches Fayetteville. North of there it runs through Shelbyville and later passes through the eastern part of the Nashville metro area, passing through the cities of Murfreesboro and Lebanon. By the time it reaches Bethpage, it joins U.S. Route 31E in another concurrency to the northeast before finally crossing the Kentucky State Line north of Westmoreland. The route is approximately from Tennessee's northern border to its southern border. Kentucky US 231 parallels Interstate 65 before reaching Bowling Green. From Bowling Green, US 231 closely parallels I-165 (formerly the William H. Natcher Parkway) until it reaches Owensboro. At Owensboro, US 231 joins US 60 (also known as the Wendell H. Ford Expressway) around the city's east side, 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. A portion of the Owensboro-area route is relatively new; in 2014, a new section from Kentucky 54 to Kentucky 2830 opened, bypassing the former bypass route. Part of that former route has been renumbered as Kentucky 603. The remainder, south of 603, is partly a dead-end city street and an abandoned lane that will eventually become part of the David Adkisson Greenbelt trail. Indiana In Indiana, 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 Loogootee before reaching Bloomfield. In Bloomfield, US 231 passes Shawnee Field, a local airport. US 231 slices through central Indiana before reaching West Lafayette, where it runs just south and west of Purdue University. Next it mostly zigzags north and west, staying close to Interstate 65, before heading straight west from Crown Point, terminating at US 41.
