Opened in 1830 to bypass the Falls of the Ohio. The first major canal in Kentucky and a critical link in 19th-century inland steamboat commerce. McAlpine Locks, the modern successor, are at the same site.

US canal on the Ohio River
The Louisville and Portland Canal was a 1.9-mile (3.1 km) 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 near 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.
