American Waterways Operators says aging lock-and-dam systems on the Mississippi and Illinois rivers are making U.S. farm exports less price-competitive. Locks are the same size while towboats have grown, roughly doubling transit times.
Slower river transit raises export logistics costs, which can weaken U.S. basis relative to competitors such as Brazil over time.
