That early trail bore little resemblance to Gravois Road of today. In fact very few, if any, of the original roads in St. Louis County can be recognized as the early trails and turnpikes laid out and traveled by the pioneers who settled this region and picked from the solid wilderness a few traffic routes which later developed into highways and boulevards. In most cases our modern highways, built to meet the needs of fast motor transportation, do not follow exactly the earlier routes which were determined largely by accommodation to the natural terrain. Modern road-building machinery and materials have solved many of the problems with which the early settlers were unable to cope.
