U.S. 431 enters Kentucky south of Adairville, where it runs north into Russellville. It continues through Russellville northbound where many new re-construction projects have widened it to a four-lane highway. U.S. 431 continues its northward journey passing through many small towns when it enters Drakesboro, after which it follows most of its original route into Central City. In Central City, U.S. 431 has a cloverleaf intersection (a former toll plaza when the parkway was toll) with the Western Kentucky Parkway. The route continues north and intersects with U.S. 62 where it then parallels the route in a westerly direction to a western bypass around the central business district of Central City, in which city it is named in honor of the Everly Brothers, locally-born prominent singers. U.S. 431 turns north at the Kentucky Route 189 and U.S. 62 bypass and continues on through many small farming communities of Muhlenberg and McLean counties. After bisecting many rural rolling hills and farms of the Western Coal Fields as well as crossing through river lowlands of the Ohio Valley on its journey to Daviess County, it enters the city of Owensboro as a four-lane highway and one of the main arterial roads into the city. Many shopping centers line its outer reaches in Owensboro.
