Figure 3-14. Tonnage on Highways, Railroad, and Inland Waterways: 2007

Trucks carry most of the tonnage and value of freight in the United States, but railroads and waterways carry significant volumes over long distances. The largest volume of freight transported by rail is coal moving between the Powder River Basin in Wyoming and the Midwest, while the principal inland waterways volume movement is along the Lower Mississippi River.
