The U.S. Department of Transportation released its 2026 National Freight Strategic Plan. The topic was covered in the USDA's Agricultural Marketing Service Grain Transportation Report highlighting grain transportation as a critical component of the nation’s freight system and outlining strategies to address persistent bottlenecks that cost agricultural shippers billions annually.
The comprehensive plan recognizes agriculture as one of the freight system’s largest sectors, with trucks moving 2.2 billion tons of agricultural products in 2025, while rail carried 265 million tons and barges transported 126 million tons.
Critical corridors face mounting pressure
Agricultural freight depends heavily on a small set of high-volume corridors connecting production regions to domestic and export markets. Nearly 60 percent of U.S. grain exports travel by barge on the Mississippi River System to Gulf elevators, while 60 percent of wheat exports pass through the Columbia-Snake River System in the Pacific Northwest.
Class I railroads originate 24 percent of U.S. grain shipments and handle 39 percent of grain export movements, making rail infrastructure critical to agricultural competitiveness.
Weather variability severely impacts grain logistics, particularly on inland waterways. Low water on the Mississippi River in 2022 forced barges to reduce capacity by up to 27 percent, causing barge rates to spike. Seasonal surges from fall corn and soybean harvests strain both rural roads and barge availability, raising transportation costs and increasing accident risks on narrow, two-lane highways.
Infrastructure aging threatens reliability
The plan warns that 80 percent of navigable lock and dam structures on inland waterways had exceeded their designed life as of 2024, risking unreliability and unplanned closures. DOT estimates that each dollar invested in inland waterways returns $1.39 to $1.83 in economic benefits, partly by shifting traffic from congested highways.
An extended closure at a major lock can trigger massive diversions, forcing thousands of truck trips onto highways and adding over $1 billion in shipper costs, according to the plan.
Shifting patterns reshape demand
Agricultural freight patterns are changing as domestic soybean crush capacity grows from 2.4 billion bushels in 2024 to an expected 2.9 billion bushels by 2027. This expansion requires more inbound truck and rail movements of soybeans to Midwestern and Plains processing clusters, while reducing long-distance rail shipments of soybeans directly to export.
Growth projections drive planning
DOT projects agricultural freight will grow 1.5 percent annually over the next two decades. From 2025 to 2050, the agency forecasts tonnage increases of 44 percent for trucking, 50 percent for rail, and 49 percent for barge and waterways.
The plan emphasizes improving real-time shipment visibility and streamlining federal processes for freight projects to better utilize existing infrastructure while building resilience against future disruptions.
