The St. Louis regional port system handled one-third of the freight on the 855-mile Upper Mississippi section in 2015, according to USACE data cited by the St. Louis Regional Freightway. The region's river terminals offer excess barge capacity and low freight rates for grains, fertilizer and other cargo.
This is background on regional port capacity rather than a new supply or price event. It has little direct effect on grain or freight prices.
