The value of freight moved between the U.S. and its North American Free Trade Agreement Partners totaled $97.4 billion during August as all five major transportation modes carried more freight, according to the U.S. Transportation Department.
The 4.6% rise is the 10th consecutive month in which the year-over-year value in current dollars of U.S.-NAFTA freight increased from the same month of the previous year.
The value of commodities moving by pipeline increased 13.2%, air by 8.4%, vessel by 4.5%, truck by 3.6%, and rail by 3.2%. The large percentage increase in the value of goods moving by pipeline is due in part to an increase in the volume of mineral fuel imports, according to the department.
Trucks carried 64.7% of U.S.-NAFTA freight and continued to be the most utilized mode for moving goods to and from both U.S.-NAFTA partners. Trucks accounted for $31.9 billion of the $52 billion of imports, or 61.4%, and $31.1 billion of the $45.4 billion of exports, or 68.5%.
Rail remained the second largest mode by value, moving 15.1% of all U.S.-NAFTA freight, followed by vessel, 5.8%; pipeline, 5.5%; and air, 3.9%.
The surface transportation modes of truck, rail and pipeline carried 85.3% of the total value of U.S.-NAFTA freight flows
