Trade using surface transportation between the United States and Canada and Mexico rose 15.5 percent in November 2010 over November 2009, but dipped 3.6 percent from October, according to the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation.

BTS reported the value of U.S. surface transportation trade with North American Free Trade Agreement partners Canada and Mexico at $68.1 billion in November 2010. Month-to-month changes can be affected by seasonal variations and other factors. 

U.S.–Canada surface transportation trade totaled $39.5 billion in November, up 12.6 percent from a year earlier. U.S.–Mexico surface transportation trade totaled $28.6 billion in November, up 19.7 percent year over year.
 
Surface transportation consists largely of freight movements by truck, rail and pipeline. In November, 86.1 percent of U.S. trade by value with Canada and Mexico moved on land.
