Wanderlust World Wanderlust World The Erie Canal (completed 1825) and the National Road (Cumberland Road, begun 1811) were the era's transformative infrastructure projects, both federally supported.
Both linked the Eastern seaboard with the interior (Old Northwest), enabling agricultural surplus to reach markets and settlers to move west.
Water route: Great Lakes → Hudson River → New York City. Slashed freight costs 90%; made NYC the commercial capital.
Overland route: Cumberland, MD → Vandalia, IL. First federal highway; facilitated wagon travel, mail, and stagecoaches.
Canal: NY state built it, but federal land grants and later improvements involved U.S. Army Corps of Engineers. Road: Built by U.S. Treasury/War Department—early federal domestic investment.
Both catalyzed urbanization (Buffalo, Cleveland, Columbus, Indianapolis), economic integration, and sectional ties before railroads superseded them. Portions remain as heritage corridors.
