Editing Butler County, Kentucky (section)

==Transportation==
For much of its history, Butler County's main line of transportation was the [[Green River (Kentucky)|Green River]]. As railroads became more important economically, the county compensated by building a series of roads to major trade centers such as [[U.S. Route 231 in Kentucky|U.S. 231]] connecting [[Beaver Dam, Kentucky|Beaver Dam]] with [[Owensboro, Kentucky|Owensboro]]. Green River was eventually closed to traffic after [[Woodbury, Kentucky|Woodbury]]'s Lock and Dam Number 4 washed out in 1965 and [[Rochester, Kentucky|Rochester]]'s Lock and Dam Number 3 was abandoned by the [[United States Army Corps of Engineers]] in 1980. Completion of the [[William H. Natcher Parkway]] (now [[Interstate 165 (Kentucky)|I-165]]) linked the area to the national interstate system in 1970.<ref name=kye/>
