The modern canal system was mainly a product of the 18th century and early 19th century. It came into being because the Industrial Revolution (which began in Britain during the mid-18th century) demanded an economic and reliable way to transport goods and commodities in large quantities.he bulk of the canal system was built in the industrial Midlands and the north of England, where navigable rivers most needed extending and connecting, and heavy cargoes of manufactured goods, raw materials or coal most needed carrying.
A barrier to the Industrial Revolution was the transportation system in the late 1700s and early 1800s. Most roads were dirt paths filled with potholes. The cost of overland transportation of goods was too expensive.It cost more to ship 300 miles over land than to ship from the United States to Europe.he free-enterprise system determines what is produced, how much is produced, and for whom the product is produced. The Industrial Revolution changed how goods were made in the United States and affected how people lived and worked.
