One of the nation’s earliest and most successful river navigation systems, its series of locks and dams, begun in 1838, has provided year-round navigation between Pittsburgh and Fairmont, WV. Millions of tons of coal shipped through the locks supplied Pennsylvanian’s important coke, iron, and steel industries.
