Eisenhower presided over the largest public-works enterprise in American history, the building of the 41,000-mile interstate highway system. He justified these projects to ensure that armies and civilian populations could move quickly in and out of cities if a nuclear attack by the Soviets were to happen. Identify the industries that benefited most from this act in the end.

Oil companies and automakers

Explanation:

These are the two groups that benefited the most from this act in the end. The construction of such enormous highway systems allowed the country to become more interconnected. This meant that long-distance trade became faster and more efficient, and thus more common. It also meant that people were able to live further away from their places of work and commute. For all of these actions to happen, people needed more vehicles and more fuel to power such vehicles. This is what allowed oil companies and automakers to benefit.
