How the Erie Canal Fueled U.S. Economic Growth (and Tax Revenue)

The Erie Canal (completed 1825) didn't directly generate federal profit, but it catalyzed massive economic expansion that swelled tax coffers:

• Transport costs dropped ~90% between Great Lakes and East Coast.
• Trade exploded: Western grain, lumber, livestock flowed east; manufactured goods, immigrants flowed west.
• Cities boomed: Buffalo, Rochester, Syracuse, Chicago grew exponentially.
• Federal revenue rose via tariffs on increased commerce and land sales in newly accessible territories.
• National market integration: Knit disparate regional economies into a continental system.

The canal cost $7 million; by 1882, tolls had returned $121 million. Its true return was the economic transformation of the young republic.
