Controversy raged over proposals to extend the road to the farthest West, to provide its upkeep by a system of tolls, and to build similar highways farther north and south. But for a time constitutional and legal difficulties were swept aside and construction continued. Columbus was reached in 1833, Indianapolis about 1840; and the roadway was graded to Vandalia, then the capital of Illinois, and marked out to Jefferson City, Missouri, although it was never completed to the last-mentioned point by federal authority. When one reads that the original cost of construction mounted to $10,000 a mile in central Pennsylvania, and even $13,000 a mile in the neighborhood of Wheeling, one's suspicion is aroused that public contracts were not less dubious a hundred years ago than they have been known to be in our own time.
The National Road has long since lost its importance as the great connecting link of East and West. But in its day, especially before 1860, it was a teeming thoroughfare. Its course was lined with hospitable farmhouses and was dotted with fast-growing villages and towns. Some of the latter which once were nationally famed were left high and dry by later shifts of the lines of traffic, and have quite disappeared from the map. Throughout the spring and summer months there was a steady westward stream of emigrants; hardly a day failed to bring before the observer's eye the creaking canvas-covered wagon of the homeseeker. Singly and in companies they went, ever toward the promised land. Wagon-trains of merchandise from the eastern markets toiled patiently along the way. Speculators, peddlers, and sightseers added to the procession, and in hundreds of farmhouses the women-folk and children gathered in interested groups by the evening fire to hear the chance visitor talk politics or war and retail with equal facility the gossip of the next township and that of Washington or New York. Great stage-coach lines--the National Road Stage Company, the Ohio National Stage Company, and others--advertised the advantages of their services and sought patronage with all the ingenuity of the modern railroad. Taverns and roadhouses of which no trace remains today offered entertainment at any figure, and of almost any character, that the customer desired. Eastward flowed a steady stream of wagon-trains of flour, tobacco, and pork, with great droves of cattle and hogs to be fattened for the Philadelphia or Baltimore markets.
