Louisville and Portland Canal

The Falls of the Ohio form the only barrier to navigation between Pittsburgh and New Orleans, and cargo was portaged around them except for a few weeks of high water each spring.

Kentucky chartered the private Louisville and Portland Canal Company in 1825; construction started March 1, 1826, and the canal opened in 1830. As built, it was 1.9 miles long and 64 feet wide and ended in a three-flight lock with a total lift of 26 feet.

Wikipedia describes it as the first major improvement completed on a major U.S. river and dates full completion to 1833. The route was later enlarged and rebuilt and is now the McAlpine Locks and Dam canal; the pin marks the lock site at the downstream end.
