Four out of five major transportation modes – truck, pipeline, vessel and air – carried less U.S. freight and with North American Free Trade Agreement (NAFTA) partners Canada and Mexico by value in 2016 than in 2015. Rail is the only major mode to carry more freight, increasing by 0.2 percent. The total value of cross-border freight carried on all modes fell 3.4 percent from 2015 to $1.069 trillion in current dollars, according to the U.S. Department of Transportation’s Bureau of Transportation Statistics (BTS).
Freight by Mode
The modal share of commodities moving by truck increased by 1.1 percentage points, rail increased by 0.5 percentage points, and air was unchanged from 2015 to 2016. The modal share of freight on other modes declined: pipeline by 0.5 percentage points and vessel by 1.1 percentage points.
A large drop in the year-over-year price of crude oil in early 2016 played a key role in the annual declines in the dollar value of goods shipped by vessel (down 20.0 percent) and pipeline (down 12.9 percent). By the end of 2016, the year-over-year price of crude oil was increasing. Average monthly prices for crude petroleum and refined fuel are available from the U.S. Energy Information Administration.
Trucks carried 65.5 percent of U.S.-NAFTA freight, a 1.1 percentage point increase from 2006, and continued to be the most heavily utilized mode for moving goods to and from both U.S.-NAFTA partners. Trucks accounted for $362.0 billion of the $572.2 billion of imports (63.3 percent) and for $338.0 billion of the $496.9 billion of exports (68.0 percent).
Rail remained the second largest mode, moving 15.5 percent of all U.S.-NAFTA freight, followed with vessel by 5.5 percent; pipeline by 4.6 percent and air by 3.9 percent. The surface transportation modes of truck, rail and pipeline carried 85.6 percent of the total value of U.S.-NAFTA freight flows.

Truck carried 67.1 percent of the $266.0 billion of 2016 exports to Canada, followed by rail, 11.2 percent; air, 5.6 percent; pipeline, 3.0 percent; and vessel, 2.5 percent.
Michigan led all states in freight with Canada in 2016 with $71.8 billion, and increase of 3.9 percent. The other top 10 states for U.S.-Canada freight in 2016 all showed year-over-year decreases, Indiana had the smallest percent decrease over 2015 by 0.3 percent. Texas had the largest percent decrease over 2015 among the top 10 states, by 15.0 percent.
