Louisville and Portland Canal : ウィキペディア英語版 | Louisville and Portland Canal
The Louisville and Portland Canal was a canal bypassing the Falls of the Ohio River at Louisville, Kentucky. The Falls form the only barrier to navigation between the origin of the Ohio at Pittsburgh and the port of New Orleans on the Gulf of Mexico; circumventing them was long a goal for Pennsylvanian and Cincinnatian merchants.〔Yater, George. ''The Encyclopedia of Louisville'', (p. 531 ). "Louisville and Portland Canal". University Press of Kentucky (Lexington), 2001. Accessed 9 October 2013.〕 The canal opened in 1830 as the private Louisville and Portland Canal Company but was gradually bought out during the 19th century by the federal government, which had invested heavily in its construction, maintenance, and improvement. The Louisville and Portland Canal became the McAlpine Locks and Dam in 1962 after extensive modernization.〔.〕 The canal was the first major improvement to be completed on a major river of the United States.〔Trescott, 694.〕 ==History==
