Trolley cars were the first motorized public transportation within city limits and also reached areas inaccessible by railroad. The line serving New Lenox ran between Chicago Heights and Joliet. Although dependable, the trolley was not often fast. As the paved Lincoln Highway developed, motorists gained a new form of independence and automobile traffic increased. Traveling by car became a way of life, reducing dependence on trolley schedules and routes, and the trolley system soon gave way to the automobile.
