NASHVILLE, Tenn. (RFD NEWS) — Grain transportation is shifting into spring mode as the Mississippi River system reopens, while rising diesel prices are expected to push freight costs higher in the weeks ahead.
The Mid-Mississippi River reopened for navigation on March 19, followed by the Upper Mississippi River reaching St. Paul, Minnesota, on March 24 — marking the final seasonal opening point. The reopening comes slightly later than last year but restores a key export corridor after winter closures. In 2025, more than 12.8 million tons of grain moved through a key lower Mississippi lock, underscoring the system’s importance to U.S. exports.
Transportation costs are now becoming a growing concern. Diesel prices have surged to $5.375 per gallon, up sharply in recent weeks, which will begin flowing into rail shipping costs through higher fuel surcharges starting in May. For long-distance routes, that could add roughly $575 per railcar to freight costs.
Shippers are already reacting. Rail demand is expected to increase in April as grain companies try to move product ahead of higher fuel surcharges. Secondary railcar markets have firmed in recent weeks, reflecting that shift in demand.
Barge and ocean activity are also strengthening, with increased vessel loadings in the Gulf and improving river traffic as navigation conditions normalize.
Transportation conditions are improving seasonally, but rising fuel costs are likely to increase overall grain shipping expenses as we move into late spring.
