Although fascinating, canal history remains one of the hidden stories of America's past. Yet canals were integral to the country's growth, providing the first long-distance "highways" that penetrated America's interior. Their importance was short-lived but came at a time when the United States was establishing itself as an industrial power. Without canals and their ability to transfer natural resources, manufactured products, and thousands of immigrants seeking a new life, America's transition from a farm-based economy to one based on heavy industry would have been delayed by several decades.
