The Canal System: Britain’s First Major Transport Network

The canal system was the first major transport network of the Industrial Revolution. Built in a wave of construction that lasted from the 1760s to the 1830s, the canals of Britain tied the industrial regions of the country together and made possible the cheap transport of bulky goods, especially coal, iron, and pottery. The canal-building mania was one of the defining features of the late eighteenth century, and it was a precondition for much of the industrial development that followed.

The Origins of the Canal System

The first modern canals in Britain were built in the late seventeenth and early eighteenth centuries, mostly for the purpose of draining land or carrying short distances of coal. The real canal era, however, began with the Bridgewater Canal, opened in 1761 by the Duke of Bridgewater to carry coal from his mines at Worsley to Manchester.

The Bridgewater Canal was the brainchild of the Duke of Bridgewater, a young nobleman who wanted to reduce the cost of transporting his coal to Manchester. The canal was engineered by James Brindley, a self-taught millwright and engineer, and it included an aqueduct, the Barton Aqueduct, that carried the canal across the River Irwell. The canal was an immediate success, and it reduced the cost of coal in Manchester by about half, encouraging the Duke to extend the canal to a longer route.

The success of the Bridgewater Canal inspired a wave of canal-building across Britain. By 1830, there were more than 2,000 miles of navigable inland waterways in Britain, including the Grand Junction Canal, the Oxford Canal, the Leeds and Liverpool Canal, the Trent and Mersey Canal, and many others. The new canals allowed bulky goods, especially coal and iron, to be transported cheaply over long distances, and they tied the industrial regions of the country together.

The Canal-Building Mania

The canal-building mania of the late eighteenth and early nineteenth centuries was one of the great episodes of infrastructure investment in British history. Hundreds of canal companies were formed, often with the support of local landowners, merchants, and industrialists who stood to benefit from the new transport links. The capital for the canals came from a variety of sources, including wealthy individuals, joint-stock companies, and even public subscriptions.

The construction of the canals required a great deal of labor and skill. The navvies, the manual laborers who dug the canals, came from all over Britain, including many from the rural areas that were losing population to the new industrial cities. The engineers who designed the canals, including James Brindley, Thomas Telford, and John Smeaton, developed new techniques for surveying, tunneling, and building locks and aqueducts.

The canals had a major economic impact. The cost of transporting goods by canal was a fraction of the cost of transporting them by road, and the canals made it possible to ship goods over long distances that would not have been possible before. The result was a major stimulus to the coal, iron, and pottery industries, all of which relied on the canals for the cheap transport of their bulky products.

The Canal Network

The canal network of Britain was concentrated in the industrial regions, especially the Midlands, the North of England, the West Riding of Yorkshire, and the Scottish Lowlands. The most important canals included the Trent and Mersey Canal, which linked the pottery industry of Staffordshire to the markets of the Midlands and the North; the Leeds and Liverpool Canal, which linked the industrial regions of Lancashire and Yorkshire; the Grand Junction Canal, which linked London to the Midlands; and the Caledonian Canal in Scotland, which provided a shortcut through the Great Glen.

The canals were particularly important for the coal industry. Before the canals, coal had to be transported by packhorse or by wagon, and the cost of transport often exceeded the cost of the coal itself. The canals made it possible to ship coal cheaply over long distances, and they helped to meet the growing demand for coal from the new industrial cities, the steam engines, and the iron industry.

The Decline of the Canal System

The canal system was at its peak in the 1830s, but it was soon to be eclipsed by the railway. The railways were faster, more reliable, and more flexible than the canals, and they could reach places that the canals could not. The opening of the Liverpool and Manchester Railway in 1830 was the beginning of the end for the canals as a major form of transport.

The decline of the canal system was not immediate, however. Many canals continued to operate profitably for several decades after the railway boom, and the canals were used for low-value, high-bulk goods that the railways did not handle well. The canals also had a network of connections with the railways, with trans-shipment points where goods could be transferred from one to the other.

By the late nineteenth century, however, most of the canal system was in decline. Many canals were taken over by the railways, which often used the canal routes for their own lines, and others were simply abandoned. The canal system never recovered from the competition of the railway, and by the early twentieth century most of the canals were in poor condition.

The Legacy of the Canals

The canal system was one of the foundations of the modern British transport system. The routes of many of the canals were later followed by railways and roads, and the skills developed by the canal engineers, including the surveying and construction techniques of James Brindley and Thomas Telford, were applied in the railway age.

The canals also had an important effect on the British landscape. The canal corridors, with their towpaths, locks, and aqueducts, became familiar features of the British countryside, and many of them are now preserved as heritage features and used for leisure activities. The canals are a reminder of a time when the slow, steady movement of goods by water was the most efficient form of transport available.

The canal system was also important for the development of the joint-stock company. Many of the canal companies were early examples of the joint-stock form, and the experience of raising capital and managing large infrastructure projects through joint-stock companies was important for the later development of the railway system. The article on capital availability describes the financial system that made the canal-building mania possible.

The Canals in the Industrial Revolution

The canal system was one of the first major infrastructure projects of the Industrial Revolution, and it was a precondition for much of the industrial development that followed. Without the cheap transport provided by the canals, the coal, iron, and pottery industries of the Midlands and the North could not have grown to the size they did, and the new industrial cities could not have been supplied with the raw materials they needed.

The canals were one of the first great public works of the new industrial age, and they helped to create the national market that would become one of the defining features of the modern British economy. The article on the railroad history describes the next great development in British transport.

What It Teaches Us

The canal mania of the 1790s is one of the first clear cases of a financial bubble in industrial history, and it set the template for the railway mania of the 1840s, the internet bubble of 1999-2000, and most of the speculative episodes since. Roughly 80 canal acts were passed in 1793 alone, and 1,257 in the period 1790-1810, of which perhaps one-third were never built and a substantial fraction of the remainder went bankrupt within a decade. The interesting question, raised by Barry Supple in the Economic History Review (1964) and developed more recently by a generation of financial historians, is whether the bubble had positive economic value — whether the over-investment in bad canal projects was offset by the survival of the good ones, and whether the mania itself trained a generation of British investors, contractors, and engineers. The honest answer seems to be: yes, but not as much as the railway-builders of the 1830s and 1840s would have liked to think. The canal mania of the 1790s produced the Bridgewater, the Trent and Mersey, and the Grand Junction, which paid for themselves; it also produced the company for the Cale and Don, the Salisbury and Southampton, and dozens of others, which did not. The unresolved question is whether the British investment culture that survived the canal mania — a culture in which 100-pound shares in speculative infrastructure projects were a normal holding for provincial attorneys and clergymen — would have developed without the bubble. The canal, in other words, may be the right place to look for the origins of the modern asset class.
