What effect did the Interstate Highway System have on life in the United States?

• A. Increased suburban development
• B. Decreased travel times
• C. Reduced truck transportation
• D. Slowed urban sprawl

Answer: (B)

The key idea is that the Interstate Highway System made long-distance travel faster and more reliable. By providing high-speed, direct, limited-access routes across the country, it cut travel times between cities and regions, transforming how people and goods moved. This increased mobility—people could commute longer distances, take weekend trips, and move toward suburbs while still staying connected to urban centers. That measurable impact on reduce travel time is what makes the option about decreased travel times the best answer. Suburban growth happened as a result of faster, more convenient travel, but it’s a consequence of the system rather than the direct effect described by the question. The highways did not reduce truck transportation; they actually boosted trucking efficiency and freight movement. And far from slowing urban sprawl, the highways facilitated it by making areas outside traditional city centers more accessible.
