In the 20th century, a new interstate system was designed and built throughout the United States. It includes huge overpasses in large cities, as well as giant bridges and paved roads that connect the nation together for transporting food, fuel, people, supplies, and military convoys. Concrete dams and metropolitan sewer systems were also built. Many of these modern marvels are starting to age-out and are now in need of repair or complete replacement, due to aging structural issues.
