No project was grander than the Erie Canal connecting New York Harbor with the Great Lakes. Geography supported the idea. The Hudson River provided a natural path from New York City to Albany, and its tributary Mohawk River pointed west through a natural break in the Appalachian Mountains — the only such break between Maine and Georgia.

The canal's clay-lined bed, or prism, was wider at top than at bottom. The Erie Canal measured 40 feet wide on its surface and 28 feet at bottom, with water 4 feet deep. The Chesapeake & Ohio Canal measured 60 feet at top and 48 feet at bottom, with a depth of 6 feet — the largest prism of its time.

Moving a boat from one level to another required a lock — a chamber with two sets of watertight doors. To raise the boat, water from the upper level was sent into the lock through valves. To lower the boat, water was drained to the lower level through another set of valves. Gravity powered the process so engines and pumps weren't necessary.

Canals generally paralleled rivers, which meant they had to cross tributaries feeding into those rivers. Sometimes a simple culvert would do, but wider tributaries were crossed with an aqueduct — a bridge carrying canal water rather than a road. The Chesapeake & Ohio Canal's Conococheague Creek Aqueduct, seen here, cost more than $43,000 when built in the mid-1830s.
