Huntington is a city in Cabell County and Wayne County in the U.S. state of West Virginia.  It is the county seat of Cabell County, and largest city in the Huntington-Ashland, WV-KY-OH Metropolitan Statistical Area, sometimes referred to as the Tri-State Area.  A historic and bustling city of commerce and heavy industry, Huntington has long-flourished due to its ideal location on the Ohio River at the mouth of the Guyandotte River.  It is home to the Port of Huntington Tri-state, the busiest inland port in the United States.  Surrounded by extensive natural resources, the industrial sector is based in coal, oil, chemicals and steel all of which support Huntington's diversified economy.  The city is a vital rail-to-river transfer point for the marine transportation industry.  Also, it is considered a scenic locale in the western foothills of the Appalachian Mountains.  This location was selected by Collis Potter Huntington as ideal for the western terminus of the Chesapeake and Ohio Railway, the predecessor of what would become CSX Transportation which still operates CSX Transportation-Huntington Division in the city to date.  The railroad founded Huntington as one of the nation's first planned communities to facilitate the railroad and other transportation related industries at the railways western terminus.  Developing fast after the railroad's completion in 1871, the site was previously a collection of agricultural homesteads, and is eponymously named for the railroad company's founder Collis Potter Huntington.  The first identifiable permanent settlement, Holderby's Landing, was founded in 1775 in the Colony of Virginia although the site had been sparsely settled by the French as early as 1609.  With the exception of the neighborhoods of Westmoreland and Spring Valley, most of the city is in Cabell County. <SEP>  Led by industrialist Collis P. Huntington, it reached from Virginia's capital city of Richmond to the Ohio River by 1873, where the railroad town (and later city) of Huntington, West Virginia was named for him. The Chesapeake and Ohio Railway was a Class I railroad formed in 1869 in Virginia from several smaller Virginia railroads begun in the 19th century. <SEP>  It is served by KY Route 2037.  A high volume railway line, operated by CSX Transportation, extends through its limits and continues in a southerly direction throughout southeastern Kentucky to western Virginia and points south.  Although its location is many miles from the nearest industrial employer, the railroad has served the community as a source of employment.  The railroad was first built through the community in 1880 by CSX's predecessor, the Chesapeake and Ohio Railway.  C&O employees who resided in Chapman caught the train as it passed through on its multiple daily runs where they reported to work.  Chapman, Kentucky is named after its first settler and prominent landowner David Chapman (1803–1845), a native of Montgomery, West Virginia.  Many of Chapman's descendants still reside in the community at this time.  Chapmansville, West Virginia, a city located on U.S. Route 119 about forty miles east of Chapman, was established in 1800 by David Chapman's uncle Ned Chapman, as he was its first postmaster and general store operator. Chapman is an unincorporated community located in Lawrence County, Kentucky, United States on the eastern bank of the Levisa Fork River.  The Chapman surname is an anglicized version of the German name Kaufmann, the German word for merchant.  David Chapman's ancestors originally emigrated to North America from Kaufmann, Germany.  Chapman is located 10 mi south of Louisa, Kentucky. <SEP> Kavanaugh, Kentucky is an unincorporated community located in Boyd County, Kentucky, located along U.S. Route 23 directly north of the Lawrence County line.  In 1984, the original alignment of U.S. 23 was replaced with a modern four-lane highway.  CSX Transportation's Big Sandy Subdivision railroad tracks pass through the community.  The railroad was formerly operated by the Chessie System and its predecessor the Chesapeake and Ohio Railway Company.
