ADM explains that the Illinois River locks and dams need major repairs beginning in July 2020. The work will fully close the river to barge traffic from July through October.
ADM says the closure will affect downstream grain shipments.
A four-month full closure of the Illinois Waterway removes a key southbound outlet for grain, which raises barge freight costs and can widen Illinois River basis versus other origins.
