Review Questions

• How did the establishment of the interstate highway system influence suburban growth in America?
  • The establishment of the interstate highway system had a profound impact on suburban growth by providing convenient access to urban centers. This allowed families to live in suburban areas while commuting to work in cities, leading to a significant population shift towards these suburban regions. The ease of travel fostered by these highways made it possible for individuals to seek larger homes and greener spaces outside crowded urban environments, thus accelerating the trend of suburbanization.
• In what ways did the interstate highway system contribute to changes in American commerce and trade practices?
  • The interstate highway system revolutionized American commerce by enhancing transportation efficiency and reducing travel times for goods. With a reliable network of highways, businesses could more easily distribute products across long distances, facilitating the rise of national markets. Additionally, this infrastructure encouraged the growth of logistics companies and modern supply chains, leading to an economy increasingly reliant on road transport for freight movement.
• Assess the broader social and environmental implications resulting from the expansion of the interstate highway system in relation to urban sprawl.
  • The expansion of the interstate highway system had significant social and environmental implications as it contributed to urban sprawl. While it provided improved access to suburban living and boosted economic opportunities, it also led to increased dependence on automobiles, traffic congestion, and air pollution. Moreover, as urban areas spread outward into rural lands, natural habitats were disrupted and agricultural lands diminished, raising concerns about sustainability and the quality of life in both urban and suburban environments.
