KY 2831 begins at an interchange with the Wendell H. Ford Expressway (U.S. Route 60, US 60) and U.S. Route 431 (US 431), It then reaches an intersection where KY 81 ends and KY 54 begins. KY 2831 ends at the intersection with KY 2245 and West Fifth Street in downtown Owensboro.
From 1929 until 1953, the entire route was originally signed as KY 75.[2] US 431 replaced the KY 75 designation in 1953, and remained on Frederica Street within the city, north of the US 60 Bypass (US 60 Byp.; Wendell H.
