A project to deepen the Mississippi River by five feet could start by October of next year. State officials say each foot of added depth would let a shipper load about $1 million more cargo per vessel.
The dredged sediment would be moved to Louisiana's coast to create up to 1,700 acres of wetlands.
A deeper channel allows larger, fuller barges and ships, which could lower per-tonne freight costs for grain exporters over time. Cheaper river transport would support farm-gate prices in the Midwest, though the benefit is years away.
