What was one effect of the interstate highway act?

One significant effect of the Interstate Highway Act of 1956 was the transformation of American transportation and commerce. It led to the construction of a vast network of highways that facilitated faster and more efficient movement of goods and people across the country. This not only boosted economic growth by enhancing trade but also contributed to the rise of suburbs, as easier access to highways made it feasible for people to live farther from their workplaces. Additionally, it had lasting impacts on urban planning and the environment, reshaping cities and contributing to increased car dependency.
