Farmers were among those who joined President Trump last week in Cincinnati to highlight the economic importance of the inland waterways system and the need to invest in upgrades to the locks and dams.

“Roughly 60 percent of the United States grain exports travel down these waterways to the Gulf,” said Trump in his remarks.

Upgrading the inland waterways infrastructure is a top priority for agricultural organizations, including the American Soybean Association and National Corn Growers Association. “We’ve long maintained that the quality of our infrastructure networks in the United States—road, rail, waterways and ports—is directly connected to the competitive advantage we have over other soybean producing countries,” said Kendell Culp, who farms in Rensselaer, Indiana and was at the Trump announcement last week.

President Trump’s infrastructure plan also includes a $200 billion investment in rural infrastructure.
