What did the Interstate Highway Act create?

A safe 41,000 mile national highway system A transcontinental railroad network A nationwide electric grid A network of deep-water ports

Correct Answer:

A safe 41,000 mile national highway system

Explanation:

The main idea here is that the Interstate Highway Act created a national system of highways. It authorized the construction of thousands of miles of safe, high-speed, limited-access roads designed to connect major cities across the United States and to improve both civilian travel and military mobility. The system eventually totaled about 41,000 miles, funded and standardized by the federal government to ensure consistency and nationwide reach. This is distinct from a transcontinental railroad network, which is a different historical transportation project, or a nationwide electric grid or a network of deep-water ports, which are separate kinds of infrastructure.
