A new report by the U.S. Department of Transportation says that commercial trucks hauled 58% of the freight moved between NAFTA countries in 2008.
Trains accounted for 15% of the goods moved, with ships (10%), pipelines (9%) and air (4%) accounting for the rest.
The DOT’s Bureau of Transportation Statistics issued the report as part of its update to the North American Transportation Statistics database.
Nearly 11 million commercial trucks entered the U.S. in 2008, with some 6 million coming from Canada and 5 million from Mexico. That freight accounted for some $970 billion in value.
The value of shipments moving between the NAFTA nations grew at an average rate of nearly 9% between 2003 and 2008, the report said.
