How did the national road help the US?

The National Road, established in the early 1800s, significantly contributed to the economic development of the United States by improving transportation and facilitating westward expansion. It connected the eastern states to the western frontier, making it easier for settlers to move and for goods to be transported. This infrastructure promoted trade, enhanced communication, and stimulated the growth of towns along the route, ultimately playing a vital role in the nation’s expansion and integration.
