WASHINGTON, D.C. – Truckers hauled 8.2 percent more freight between Canada, the U.S. and Mexico in September 2014 than in September 2013, according to the U.S. Transportation Department.

NAFTA freight totalled $102.2 billion in September, making it the seventh month in a row to go over $100 billion.

Year-to-date NAFTA freight is 4.9 percent higher than during the same time in 2013.

Trucks carried 54 percent of the $57.4 billion of freight to and from Canada, followed by rail at 16.1 percent, pipeline at 13.3 percent, vessel at 5.3 percent and air at 4.3 percent. The surface transportation modes of truck, rail and pipeline carried 83.4 percent of the total U.S.-Canada freight flows.

Year-over-year, the percent change in the value of U.S.-Canada freight moved by pipeline increased the most of any mode, growing 19.2 percent. Freight moved by truck increased six percent and rail by 3.3 percent, while air and vessel were static.

Trucks carry three-fifths of U.S.-NAFTA freight and are the most heavily utilized mode for moving goods to and from both U.S.-NAFTA partners (Canada and Mexico). Trucks accounted for $31.2 billion of exports and $30.1 billion of imports.

Of the $7.8 billion increase in the value of US-NAFTA freight from September 2013, truck freight contributed the most, $4.9 billion, followed by pipeline, $1.4 billion.
