The corridor
Mississippi River barge corridor
Domestic corridorUS InteriorThe barge highway carrying US grain from the Midwest to Gulf export elevators, plus a large volume of fertiliser, coal and petrochemicals moving the other way. Its capacity is set by water level, so it fails seasonally and predictably rather than suddenly.
- Low water forces reduced barge drafts and shorter tows, cutting tonnage per trip without closing the river — a partial capacity loss rather than a stoppage.
- Displaced grain moves to rail and truck, tightening those markets in the Midwest during the autumn harvest peak.
- Barge freight rates quoted as a percentage of tariff respond within days of a draft restriction, ahead of any change in export volumes.
