Railroads were faster and cheaper than canals to construct, and they did not freeze over in the winter. Steamboats played a vital role in the United States economy as well. They stimulated the agricultural economy of the west by providing better access to markets at a lower cost. Farmers quickly bought land near navigable rivers, because they could ship their products out to other countries. Due to the foreign trade it helped strengthen the trade relationship between New England and the Northwest. The transportation development had many positive economic changes in the United States. The change in transportation led to social changes as well. Due to the construction of railroads in the urban areas there was more settlement in places where transportation was available such as New York. Due to the increase in transportation, white plantation owners increased their need for slave labor on the cotton farms as well as stricter slave code policies were increased in the South. Due to the advanced railroad system Americans are able to move westward very easily
