"Every day, millions of people get in their cars and trucks and hit the road. In order to support this huge volume of traffic, a strong system of highways and roads is essential. This comprehensive title examines how early trails and dirt roads eventually led to the high-speed freeways that now connect our cities, states, and countries. Readers are introduced to various types of roads, important rules and safety measures, and the many workers who ensure the maintenance and development of our highway system. Color photos and fun facts accompany high-interest text in this first-hand look at a complex and crucial network."--Provided by publisher.
