1. Evacuation of Cities in Case of Nuclear Attack: During the Cold War, there was a constant fear of a nuclear attack on the United States by the Soviet Union. In case of such an attack, it was important to have a way to evacuate large numbers of people from cities that could be targeted. The interstate highway system provided a way to do this quickly and efficiently.
2. Dispersal of Industry and Commerce: In order to make it more difficult for the Soviet Union to target the United States with nuclear weapons, it was important to disperse industry and commerce throughout the country. The interstate highway system made it possible for businesses to locate in rural areas, which made them less vulnerable to attack.
3. Movement of Military Forces: The interstate highway system also provided a way for the military to move troops and supplies quickly and easily. This was especially important during the Korean War and the Vietnam War.
In addition to these civil defence objectives, the interstate highway system also had a number of other benefits, including:
1. Economic Growth: The interstate highway system helped to stimulate the economy by creating jobs and increasing trade.
2. Increased Travel and Tourism: The interstate highway system made it possible for people to travel more easily and affordably, which led to increased travel and tourism.
3. Safety: The interstate highway system helped to improve safety by reducing the number of accidents and fatalities.
Overall, the interstate highway system was a major engineering feat that had a significant impact on the United States. It not only helped to improve national security, but also stimulated the economy, increased travel and tourism, and improved safety.
