Most of the improved highways and many bridges were built as business ventures by private interests. Promoters charged tolls, the rates being set by the states. Tolls were collected at gates along the way; hinged poles suspended across the road were turned back by a guard after receipt of the toll. Hence these thoroughfares were known as turnpikes, or simply pikes.
The profits earned by a few early turnpikes, such as the one between Philadelphia and Lancaster, caused the boom in private road building, but even the most fortunate of the turnpike companies did not make much money. Maintenance was expensive, and traffic spotty. (Ordinary public roads paralleling turnpikes were sometimes called “shunpikes” because penny-pinching travelers used them to avoid the tolls.) Some states bought stock to bolster weak companies, and others built and operated turnpikes as public enterprises. Local governments everywhere provided considerable support, for every town was eager to develop efficient communication with its neighbors.
Despite much talk about individual self-reliance and free enterprise, local, state, and national governments contributed heavily to the development of what in the jargon of the day were called “internal improvements.” They served as “primary entrepreneurs,” supplying capital for risky but socially desirable enterprises with the result that a fascinating mixture of private and public energy went into the building of these institutions. At the federal level even the parsimonious Jeffersonians became deeply involved. In 1808 Secretary of the Treasury Albert Gallatin drafted a comprehensive plan for constructing much-needed roads at a cost of $16 million. This proposal was not adopted, but the government poured money in an erratic and unending stream into turnpike companies and other organizations created to improve transportation.
Logically, the major highways, especially those over the mountains, should have been built by the national government. Strategic military requirements alone would have justified such a program. One major artery, the Old National Road, running from Cumberland, Maryland, to Wheeling, in western Virginia, was constructed by the United States between 1811 and 1818. In time it was extended as far west as Vandalia, Illinois. However, further federal road building was hampered by political squabbles in Congress, usually phrased in constitutional terms but in fact based on sectional rivalries and other economic conflicts. Thus no comprehensive highway program was undertaken in the nineteenth century.
While the National Road, the New York Pike, and other, rougher trails such as the Wilderness Road into the Kentucky country were adequate for the movement of settlers, they did not begin to answer the West’s need for cheap and efficient transportation. Wagon freight rates averaged at least thirty cents a ton-mile around 1815. At such rates, to transport a ton of oats from Buffalo to New York would have cost twelve times the value of the oats! To put the problem another way, four horses could haul a ton and a half of oats about eighteen or twenty miles a day over a good road. If they could obtain half their feed by grazing, the horses would still consume about fifty pounds of oats a day. It requires little mathematics to figure out how many pounds of oats would be left in the wagon when it reached New York City, almost 400 miles away.
Turnpikes made it possible to transport such goods as clothing, hardware, coffee and books across the Appalachians, but the expense was considerable. It cost more to ship a ton of freight 300 miles over the mountains from Philadelphia to Pittsburgh than from Pittsburgh to Philadelphia by way of New Orleans, more than ten times as far. Until the coming of the railroad, which was just being introduced in England in 1825, the cost of shipping bulky goods by land over the great distances common in America was prohibitive. Businessmen and inventors concentrated instead on improving water transport, first by designing better boats and then by developing artificial waterways.
