Erie Canal

Completed in 1825, the Erie Canal connected Albany to Buffalo across 363 miles, becoming the first navigable waterway linking the Atlantic to the upper Great Lakes above Niagara Falls. It cut transport costs dramatically, made New York City the dominant American port, and accelerated settlement of the Great Lakes region. The Cayuga-Seneca Canal, a branch running 12 miles into the Finger Lakes, brought that commerce directly into this wine country. Today the canal runs primarily recreational traffic, but the engineering argument it settled — that the interior was reachable — still shapes everything around it.
