切萨皮克和俄亥俄运河国家历史公园位于华盛顿特区和马里兰州。艾森豪(英语:Dwight Eisenhower)总统为了保留被忽视的切萨皮克和俄亥俄运河残存遗迹,于1961年建立了一个国家纪念区。运河和纤路沿着波托马克河从华盛顿特区乔治敦延伸至马里兰州坎伯兰郡,总长184.5英里(296.9千米) 。 2013年,这条路被指定为美国第50号自行车道的第一部分。[2] [3]
切萨皮克和俄亥俄运河
[编辑]![](http://upload.wikimedia.org/wikipedia/commons/thumb/3/3b/Cumberland_Basin_looking_North.jpg/220px-Cumberland_Basin_looking_North.jpg)
切萨皮克和俄亥俄运河(也称为“大旧渠”(英语:the Grand Old Ditch)或“ C&O运河”(英语:C&O Canal))的建设始于1828年,直到1850年运河建到坎伯兰时才结束。[4] :1 工程停止时,其实仍距离原本设想的目的地匹兹堡很遥远。在停工之后,人们有时候仍会讨论继续延长这个目前长达184.5英里的运河。例如,1874年提出的一条建议,打算挖一条8.4英里(13.5千米)的隧道穿越亚利加尼山脉,[5] 再借由另一条隧道接上宾夕法尼亚运河。[6]即使巴尔的摩和俄亥俄铁路公司(B&O)比运河还要早8年就通车道坎伯兰,但运河并没有完全作废。一直到1870年代中期,较大的火车头以及空气刹车被采用后,铁路运送费用比运河还低,运河的命运才被堵死。[7]
C&O运河于1831年至1924年运营,主要用于将煤炭从亚利加尼山脉运至华盛顿特区。[8] :6 运河于1924年关闭,部分原因是几次严重的洪灾摧毁了运河的财务状况。 [9]
联邦政府购买运河
[编辑]![](http://upload.wikimedia.org/wikipedia/commons/thumb/b/b8/CCC-C%26O.jpg/220px-CCC-C%26O.jpg)
1938年,B&O铁路公司将运河交与美国政府,以换取一笔联邦复兴金融公司的贷款。[10] 政府计划将其修复作为休闲游憩区,以及当作大萧条时期失业者的就业计划。到1940年,平民保育团的非裔参与者修复了最初的22英里(35千米),约从乔治城到维奥莱特斯船闸(第23号船闸),并且重新引水进入此段运河使其回到可以运作的状态。[11] 1941年,第一艘运河快船开始营运,其动力为驴子在岸上拉动牵引。[12] 1960年代,约翰·昆西·亚当斯号(英语:John Quincy Adams)取代了运河快船。
当美国参战二战时,修复计划被暂停,以将资源挪作他用。1941年,哈里·阿西(英语:Harry Athey)向总统富兰克林·罗斯福(英语:Franklin Roosevelt)建议,该运河可以改建为地下高速公路或防空洞,其屋顶可用于飞机起降。由于洪水经常发生,整个想法被认为是不切实际的。[13] 1942年,春汛摧毁了重新注水的运河区段。美国国家公园管理局(NPS)官员亚瑟·德玛瑞(英语:Arthur E. Demaray)敦促恢复从1号水坝开始的运河,以便在正常水渠被敌后破坏火轰炸摧毁时,为达勒卡里亚水库供水。由于这项使运河变成了国家安全问题,1942年,战时生产委员会批准了这项计划。[14] 到1943年,国会已为这项工作提供了资金,维修已完成,而公园服务处则于1943年10月恢复了乘船游览。[15]
国会对将运河和纤路发展为公园大道的想法表达了兴趣。由于从1920年代到1940年代的洪水,陆军工兵团提议修建14座水坝,这些水坝将永久淹没74英里的纤路,以及莫诺克西和安提坦引水道。[16] 1945年左右,工兵团团想要拆除8号水坝,并在坎伯兰地区设置堤防。拆除8号水坝将使得对5号水坝以上运河段重新补水的希望破灭。国家公园管理局配合了工兵团团来完成前述的计划,因为让通往坎伯兰的运河整段都保持营运状态过于昂贵,且希望保留运河的西部地区。[17]
建立国家公园

道格拉斯的徒步旅行
[编辑]一些人反对将运河翻到汽车上的想法,包括美国最高法院大法官威廉·道格拉斯(英语:William O. Douglas) 。 1954年3月,道格拉斯带队,从坎伯兰走纤路徒步旅行至华盛顿,为期八天。[10] 尽管总参加人数有58人,但只有9人(包括道格拉斯和奥劳斯·穆里)走完全程共184.5英里(297千米) 。这次旅行之后,道格拉斯大法官成立了一个委员会起草保留和保护运河的计划。该委员会后来在1957年成为C&O运河协会。[18] 作为该小组的主席,他对公园的承诺被认为是成功的。
纤路
[编辑]1958年,整条道路被清理以供徒步旅行之用,并从华盛顿特区乔治城区域第34街的驴子桥(英语:Mule Bridge)[注释 1] 到马里兰州沃德沃特(英语:Widewater)[注释 2] 12英里的纤路建立脚车道。[19] 脚车道于1958年11月22日开放,道路为是泥泞的纤路上铺上碎蓝石而成。[20] 到1960年,运河纤路已全程通行自行车。[21]
国家纪念区以及国家公园
[编辑]1961年,艾森豪(英语:Dwight Eisenhower)总统根据《古迹保存法》将运河定为国家纪念区,但这更加强了反对派要将运河立为国家公园的想法。另有一些人支持将波托马克河立为国家河流(英语:national river)。[22] 在十年左右的时间,政治气氛发生了变化,国家河流这个想法的支持度不足,于是将运河变成历史公园的想法几乎没有受到反对。切萨皮克和俄亥俄运河国家历史公园法案[23]确立了运河的国家历史公园定位,总统理查德·尼克松于1971年1月8日将其签署为法律。 [24]
1996年洪水
[编辑]![](http://upload.wikimedia.org/wikipedia/commons/thumb/1/11/Canal_Flood_of_1996.jpg/220px-Canal_Flood_of_1996.jpg)
1996年的冬季和夏季,各发生了一次洪水。一月份的暴风雪过后,接着大雨及积雪融化,造成了洪水和径流。这场重大的冬季洪水覆盖了80%至90%的运河和纤路,运河与相邻的波托马克河出现成了高水位。洪水造成的侵蚀导致纤路以及运河和公园的大部分基础设施受到严重破坏。冬季洪水过后,迫切地需要志愿者来处理洪水造成的破坏。不幸的是,在9月,弗兰飓风对运河许多部分造成了更大的破坏,需要工作人员和志愿者复原甚至重建纤路及给运河重新浇水。这些重大项目需要大量时间和金钱才能完成。[25]
恢复工作
[编辑]如今,一些组织致力于保护和恢复公园的美丽和历史。 C&O运河信托[26]成立于2007年,是国家公园管理局的官方非营利合作伙伴。 C&O运河协会[27]是一个全志愿者组织,成立于1954年,其忠旨在保护C&O运河和波托马克河盆地的自然及历史环境。他们共同在运河基础设施的修复工作中取得了进展。他们修复纤路,并重新对运河注水,使其能漂亮地面对游客和野生动植物,并在游客中心通过互动方式向大众介绍了运河的丰富历史。沿着运河共有六个由国家公园管理局管理的游客中心:乔治城、大瀑布 (波托马克河)、不伦瑞克 (马里兰)、威廉斯波特、汉考克、以及坎伯兰。[28]
当前的修复和建设工作包括对卡诺卡其克引水道进行修复和补水[29]、复原3号和4号船闸[30]、修复大瀑布(20号)和斯温(21号)船闸。[31] 2019年5月30日开始第二阶段工程,针对波波隧道。[32]
