The 17th Street Canal is the largest and most important drainage canal in the city of New Orleans. Operating with Pump Station 6, It moves water into Lake Pontchartrain. The canal, along with the Orleans Canal and the London Avenue Canal, form the New Orleans Outfall Canals. The 17th Street Canal forms a significant portion of the boundary between the city of New Orleans and Metairie, Louisiana. The canal has also been known as the Metairie Outlet Canal and the Upperline Canal. ==History== The canal that was to become later known as the 17th Street Canal seems to have had its origin at the start of the 1850s as a canal dug through swampy ground to raise a parallel right of way where the Jefferson and Lake Pontchartrain Railway was built. The railway, in business from 1853 through 1864, connected the town of Carrollton, Louisiana (along the Mississippi River front) with a shipping port on Lake Pontchartrain at what became Bucktown, Louisiana, a distance of about . At the time, most of the land between the two terminals was undeveloped swamp. Meanwhile, in 1858, a secondary canal was built to aid in drainage in the low swampy area in "back of town" from Carrollton, with its head at what is now the intersection of Dublin and Palmetto streets, connecting to the Railway canal a short distance on the river side of the Metairie Ridge. The railway was discontinued on 31 December 1864 as competing rail lines between the river and lake were more successful. The city of New Orleans annexed Carrollton, and the canal became the boundary line between Orleans Parish and Jefferson Parish. As the canal marked the up-river limit of Orleans Parish, it became known as the Upperline Canal. The spur canal in the back of Carrollton was beside a projected street numbered "17th Street" (although at the time there was little actual development in back of Claiborne Avenue), and that canal was thus the first to be known as the "17th Street Canal", a name which would later come to commonly refer to the large canal which this is connected to. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「17th Street Canal」の詳細全文を読む スポンサード リンク
