Review Questions

• Explain the primary objectives behind the creation of the Interstate Highway System.
  • The Interstate Highway System was established in 1956 with two primary objectives: to improve national defense capabilities by facilitating the rapid movement of military personnel and equipment, and to support economic development by enhancing the efficient transportation of goods and people across the country. The system's high-speed, limited-access design was intended to enable the quick and reliable movement of vehicles, while its nationwide connectivity was seen as crucial for both military and commercial purposes.
• Describe the impact of the Interstate Highway System on the development of suburban and exurban communities.
  • The construction of the Interstate Highway System had a significant impact on the growth and development of suburban and exurban communities across the United States. The system's emphasis on high-speed, limited-access highways made it easier for people to live farther from urban centers and commute to work, leading to the rapid expansion of residential and commercial development in outlying areas. This, in turn, contributed to the decline of public transportation in many communities and the increased reliance on personal vehicles, ultimately shaping the patterns of urban and regional development in the latter half of the 20th century.
• Analyze the criticisms that have been leveled against the Interstate Highway System and its impact on the environment and urban communities.
  • The Interstate Highway System has faced criticism for its negative impacts on the environment and urban communities. The system's emphasis on high-speed, limited-access highways has been linked to increased urban sprawl, as the ease of travel has facilitated the development of residential and commercial areas in outlying regions. This has contributed to environmental degradation, including the loss of natural habitats and the increase in greenhouse gas emissions from personal vehicles. Additionally, the system's design has been criticized for prioritizing automobile transportation over public transit, leading to the decline of walkable urban neighborhoods and the marginalization of low-income and minority communities that lack access to reliable transportation options. These criticisms have sparked ongoing debates about the need to balance the economic and military benefits of the Interstate Highway System with its environmental and social impacts.
