Compared with January 2014, the SA index increased 6.6%, which was the largest year-over-year gain in over a year.

“Truck tonnage continued to improve in January, marking the fourth straight gain totaling 3.5%,” said ATA Chief Economist Bob Costello. “Last year was slightly better for truck tonnage than we originally thought and I am expecting that momentum to continue in 2015.”

Costello added that since bottoming out in March 2014, tonnage is up 6.7%.
