Which was opened first, Louisville and Portland Canal or Schuylkill Canal?
Louisville and Portland Canal The Louisville and Portland Canal was a 2 mi 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. 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.
NS Line (Portland Streetcar) The North/South Line (NS Line) is one of two routes forming the Portland Streetcar system in Portland, Oregon, United States. The 3.9 mi route, operated by Portland Streetcar Inc. (PSI) and TriMet, connects the Nob Hill District to the South Waterfront. Opened over its first 2.4 mi section in 2001, it was the initial line of the Portland Streetcar system and was the first new streetcar line in the United States since World War II to use modern vehicles. It was given the name North/South Line (abbreviated as NS Line) in September 2012, with the opening of the system's second line (the Central Loop, or CL Line), having previously had no distinct route name.
