Barge availability along the Mississippi River is limited, causing an uptick in trail and rail demand to move grain for export. National Grain and Feed Association CEO Mike Seyfert says the amount of rail carloads from St. Louis to the Mississippi Gulf in mid-October nearly doubled compared to one year ago. Freight rates are higher, too. “On October 18, it cost us $72.58 per ton for barge rates from St. Louis to the Gulf. Last year, it was $31.56 per ton.
