From the first rude ridgeways to the modern interstate highway, the evolution of the road is a fascinating story. Readers will learn the progression of roads from the first ridgeways, roads in the ancient world, Roman roads and the development of the revolutionary McAdam Road. American Indians developed an extensive system of trails for both trade and war. The pioneers used parts of these trails to blaze the first traces that penetrated the interior of the developing United States. Readers can also follow the progression of the United States highway system from the first named highways to the modern interstate system of roads first established in the late 1950's.
