A flat-bottomed, cargo-carrying vessel designed to transport dry bulk (grain, coal, lumber, gravel, etc.) and liquid bulk (petroleum, vegetable oils, molasses, etc.) across rivers and canals. Because they have no locomotion, they are moved by towboats. Measuring 200 feet long and 35 feet wide with a draft of 9 feet, a standard barge can carry 1,500 tons, which equals up to either 15 railroad cars or 60 truckloads of cargo.
