What were some challenges to early forms of transportation?

In the early 19th century, most roads were dreadful. They served local needs, allowing farmers to get produce to market. Americans who did travel long distances overland to settle the West rode on wagon trails, like the Oregon Trail, rather than well-defined roads. Still, a few major roads served as important transportation links. The National Road, initially funded by the federal government, stretched from Cumberland, Maryland, to Columbus, Ohio by 1833.
