Infrastructure projects in New York are much more difficult today

The Erie Canal was one of the most ambitious infrastructure projects in American history. Many have said such an effort would be impossible today. This article explores why that is the case and ponders the future of large-scale American infrastructure development.

The Erie Canal was opened Oct. 25, 1825, with a group of boats from Buffalo to NYC

The unlikely engineering project connecting the Midwest to the Atlantic saw a ceremonious opening as Governor Dewitt Clinton rode with a flotilla of boats from Buffalo on Lake Erie to New York City.

The Appalachian Mountains blocked east–west boat travel until the Erie Canal

The Appalachian Mountains, spanning from Alabama to Canada, long hindered inland commerce. The Erie Canal created the first reliable water route through the range by leveraging the natural valley of the Mohawk River, revolutionizing trade and migration.

The Erie Canal runs 363 miles from Albany to Buffalo

Mostly using the low elevations of the Mohawk River Valley, the canal project connected the Great Lakes to the Atlantic seaboard for the first time. This site has a series of old and new maps of the canal.

Amateur engineers built America’s first great infrastructure project

With no engineering schools in the US, the Erie Canal was designed and built by self-taught amateurs who improvised new methods and became known as the “Erie School of Engineering.”

Jefferson’s Lewis and Clark expedition joined the centuries-long hunt for Northwest Passage

For centuries, leaders pursued a direct seafaring trade route from Europe to Asia. Jefferson joined this quest by sending Lewis and Clark west, though they confirmed no such practical interior route existed across the continent.

As president, Thomas Jefferson expanded federal power despite opposing centralized authority

Although Jefferson argued for limited national power, his presidency expanded federal authority through actions such as the Louisiana Purchase, territorial governance, and federal enforcement—reflecting a pragmatic departure from his earlier strict interpretation of the Constitution.

Reflections on the Erie Canal traces the waterway from its 1825 opening to its evolving role today. Each short video in this 10-part series explores a different aspect of the canal and its legacy today.

Jefferson omitted a plan to go beyond the Louisiana Territory in his funding request

In January of 1803, the president sought $2,500 to fund the expedition (though it likely cost closer to $50,000). The ostensible rationale for the journey was to explore the newly purchased territory, but Jefferson did not mention he wanted Lewis and Clark to go beyond the newly acquired territory for several reasons.

Jefferson sent Lewis and Clark to map, trade, and secure the West

Beyond seeking a water route to the Pacific, Jefferson tasked the Corps of Discovery with mapping the new Louisiana Territory, cataloging its resources, and establishing trade with Native nations.

Madison urged Jefferson to accept the Louisiana Purchase despite constitutional concerns

As secretary of state, James Madison helped negotiate the 1803 Louisiana Purchase and persuaded Thomas Jefferson to proceed, arguing that the strategic and economic stakes outweighed the unresolved constitutional questions.

Local limestone made waterproof cement for the Erie Canal

In 1818, engineer Canvass White discovered that limestone near Chittenango, New York, could be processed into hydraulic (or waterproof) cement. This breakthrough replaced costly European imports, enabling watertight locks and aqueducts and revolutionizing American construction.

The original canal had 83 different hand-operated locks

Locks are gated chambers that raise and lower boats between stretches of water at different levels. On the Erie Canal, 83 such locks managed a 565-foot elevation change from the Hudson River to Lake Erie.

The canal carried germs as well as goods

In 1832, North America’s first cholera epidemic spread inland by way of the Erie Canal, carried by immigrants arriving on ships. Fearful towns barred passengers from disembarking, yet cholera, smallpox, and other diseases still traveled the waterway.

Before dynamite was invented, Erie Canal builders blasted rock with gunpowder

Constructed decades before the invention of dynamite, the Erie Canal’s toughest obstacles were blasted through using black powder charges.

Erie Canal builders invented the “stump puller” to clear forests

One ingenious device created for the Erie Canal was the stump puller—a horse-powered machine using levers and chains to rip tree stumps from the ground.

The US finished what the French had started with Panama's canal

For about two decades, Suez Canal-builder and Frenchman Ferdinand de Lesseps led the project, but financial troubles forced it into the hands of the US, who completed it in 1914. This timeline, made to accompany the definitive PBS American Experience documentary about the canal, highlights major moments in its construction.

Jefferson feared European control in the West of North America

Jefferson pushed for the Louisiana Purchase to prevent France or Spain from dominating the western frontier, securing control of the Mississippi River and vast lands that he felt were essential to America’s strategic and economic future.

Thomas Jefferson is rumored to have anonymously submitted a design for the White House

Of the design submissions for the White House, one is rumored to have been submitted by Thomas Jefferson, an amateur architect. Though his design did not win, he later influenced the grounds as president, adding formal gardens, wooded areas, and a carriage drive.

The canal became a highway for American reform movements

Beyond goods, the canal carried ideas. Its corridor hosted Second Great Awakening revivals and became a center for activism—fueling abolitionist networks, women’s suffrage organizing, and other reform movements.

The Erie Canal fueled a surge in westward settlement

By providing cheap, reliable transport to the interior, the canal made western lands more accessible. Farmers, traders, and immigrants moved into the Great Lakes region, accelerating population growth.

Thomas Jefferson and John Marshall clashed over national power and states' rights

Distant cousins Jefferson and Marshall advanced opposing constitutional visions—Jefferson favoring states' rights and local majorities, while Marshall defended broad federal authority and judicial review. Through decisions such as McCulloch v. Maryland, Marshall advanced national supremacy over state resistance.

Roughly 25,000 workers died building the canal

For each mile of canal that was built, 500 workers lost their lives. The threats came from multiple fronts: mudslides, floods, earthquakes and disease-carrying mosquitoes. Workplace accidents became so common that artificial limb manufacturers competed for contracts with the canal builders.

The Erie Canal transformed New York City into America’s banking capital

By redirecting western trade through New York Harbor, the canal turned New York into the nation’s commercial hub. This surge in commerce shifted financial power from Philadelphia to Wall Street, establishing the city as America’s banking capital.

The ancient Egyptians built prototypes of the modern Suez Canal

The idea to facilitate trade between the Mediterranean Sea and the Red Sea and connect the Eurasian continent was apparent even to pharaohs in the second millennium BCE. Though no physical traces remain, contemporary accounts attest to early, shorter versions of the canal, including from Herodotus.

The Barbary Wars were an early test of whether a president could wage war without a formal declaration from Congress

Jefferson sent naval forces against North African pirates without a congressional declaration of war, acting under his own authority. Years later, Madison took the opposite approach and formally sought congressional authorization.

Thomas Jefferson delivered his 1801 State of the Union address in writing

In 1801, President Jefferson ended in-person State of the Union addresses, feeling they were too monarchial, and sent written messages instead—a practice that lasted until 1913. His first message was written and sent via his secretary, Meriwether Lewis, who later led the Lewis and Clark expedition.

The rivalry between Alexander Hamilton and Thomas Jefferson centered on federalism—the question of how much power the federal government should hold relative to the states.

Alexander Hamilton and Thomas Jefferson clashed over how power should be divided in the new republic—Hamilton favoring a strong national government with broad implied powers, and Jefferson warning that such authority would erode state power and threaten republican liberty.

The Panama Canal was the first to use a lock-and-lake system on a massive scale.

The century of the Panama Canal
