While surface transportation trade among the United States, Canada and Mexico saw a 19.5 percent, there was little residual impact along the Interstate 5 corridor in Southern Oregon.

While surface transportation trade among the United States, Canada and Mexico saw a 19.5 percent increase, there was little residual impact along the Interstate 5 corridor in Southern Oregon.

While the U.S. Department of Transportation reported the largest year-over-year gain in nearly 10 years, north-bound commercial trucking activity at Oregon's port of entry station near Ashland saw a 3.6 percent decline in January.

There was $56.7 billion in trade among the North American Free Trade Agreement partners in January, the largest year-to-year increase since March 2000. That came on the heels of a 10.5 percent rise in December, the first year-over-year increase since September 2008.

But that activity failed to increase truck traffic in Southern Oregon, which has seen a consistent decline for the past three years.

Oregon Department of Transportation counted 35,679 trucks passing through the Ashland port of entry in January, down from 37,014 in January 2009.

"Vehicle miles traveled by trucks and our weighing across the state are down since the peak year of 2007," said ODOT spokesperson Sally Ridenour.
