Imagine you are an Ohio wheat farmer in 1810. You have a giant wagon full of grain, but the big city markets are hundreds of miles east across muddy trails and rugged mountains.
Moving that heavy load with horses took weeks, and shipping one ton of grain cost about $100 — often more than the grain was even worth! How could western farmers and eastern city folks ever do business?
The first big fix was to build better paths across the land. But what makes a dirt trail turn into a real road?

Smooth Roads Beat Mud Tracks

A turnpike is a crushed-stone or gravel toll road that travelers pay a small fee to use. The name comes from the turnstile pike or pole that swung open once the toll was paid.
In 1811, the federal government started paving the National Road, which stretched all the way from Maryland across the Appalachian Mountains to Illinois, cutting travel times in half.
Smooth stone roads were great for wagons, but water was still the easiest way to float super heavy cargo. What happens when the river flows in the wrong direction?

Steamboats on Inland Waterways

Inland waterways are rivers and lakes inside a country's borders, like the Ohio and Mississippi Rivers. Flatboats could easily float downstream with the current, but rowing back upstream against the rushing water took months of brutal muscle power.
In 1807, inventor Robert Fulton proved that steam engines could spin paddlewheels to push boats smoothly against powerful river currents. Soon, steamboats carried tons of frontier crops down to New Orleans and brought factory goods back up north in just days.
Rivers worked wonders if they flowed where you wanted to go. But what if a giant wall of mountains stood between the Great Lakes and the Atlantic Ocean?
