Small wonder that western producer and eastern dealer alike became interested in internal improvements; or that under the double stimulus of private and public enterprise Indian trails fast gave way to rough pioneer roadways, and they to carefully planned and durable turnpikes. Long before the War of 1812, Jefferson, Gallatin, Clay, and other statesmen had conceived of a great highway, or series of highways, connecting the seaboard with the interior as the surest and best means of promoting national unity and strength; and, in the act of Congress of 1802 admitting the State of Ohio, a promising beginning had been made by setting aside five per cent of the money received from the sale of public lands in the State for the building of roads extending eastward to the navigable waters of Atlantic streams. In 1808 Secretary Gallatin had presented to Congress a report calling for an outlay on internal improvements of two million dollars of federal money a year for ten years; and in 1811 the Government had entered upon the greatest undertaking of its kind in the history of the country. This enterprise was the building of the magnificent highway known to the law as the Cumberland Road, but familiar to uncounted emigrants, travelers, and traders--and deeply embedded in the traditions of the Middle States and the West--as the National Road. Starting at Cumberland, Maryland, this great artery of commerce and travel was pushed slowly through the Alleghanies, even in the dark days of the war, and by 1818 it was open for traffic as far west as Wheeling. The method of construction was that which had lately been devised by John McAdam in England, and involved spreading crushed limestone over a carefully prepared road-bed in three layers, traffic being permitted for a time over each layer in succession. This "macadamized" surface was curved to permit drainage, and extra precautions were taken in localities where spring freshets were likely to cause damage. 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.
