The Chesapeake and Ohio Canal National Historical Park is a United States National Historical Park located in the District of Columbia and the states of Maryland and West Virginia. The park was established as a National Monument in 1961 by President Dwight D. Eisenhower in order to preserve the neglected remains of the Chesapeake and Ohio Canal along the Potomac River along with many of the original canal structures. The canal and towpath trail extends from Georgetown, Washington, D.C. to Cumberland, Maryland, a distance of , and was designated as the first section of U.S. Bicycle Route 50 on October 23, 2013. ==The Chesapeake and Ohio Canal== (詳細はPittsburgh, Pennsylvania. Instead, the canal terminated at Cumberland for a total distance of approximately 184.5 miles. Occasionally there was talk of continuing the canal, e.g. in 1874, an 8.4 mile long tunnel was proposed to go through the Allegheny Mountains,〔Hahn, Pathway. 257〕 and there was a tunnel built to connect with the Pennsylvania canal.〔 p. ix. Davies does not indicate if this tunnel was ever used, nor its location.〕 Even though the Baltimore and Ohio Railroad (B&O) beat the canal to Cumberland, having arrived eight years earlier, the canal was not entirely obsolete. It wasn't until the mid 1870s that through improved technology, specifically with larger locomotives and air brakes, the railroad was able to set rates lower than the canal, sealing its fate.〔Davies, p. ix〕 The C&O Canal operated from 1831 to 1924 and served primarily as a means to transport coal from the Allegheny Mountains to Washington D.C. The canal was closed in 1924 in part due to several severe floods that had a devastating impact on the financial condition of the canal.
