Following the advent of the steamboat, the United States saw an incredible growth in the transportation of goods and people, which was key in westward expansion. Prior to the steamboat, it could take between three and four months to make the passage from New Orleans to Louisville, averaging twenty miles a day. With the steamboat this time was reduced drastically with trips ranging from twenty-five to thirty-five days. This was especially beneficial to farmers as their crops could now be transported elsewhere to be sold.
