Jebba, Lokoja, and Onitsha are examples of river ports. A river port is a location on a river that is designated for the loading and unloading of ships and other watercraft. These ports are established in areas where a river is deep enough to allow large vessels to dock and unload their goods. River ports serve as important transportation and trade hubs, connecting inland regions to larger bodies of water and facilitating the movement of goods to different parts of the country or even across international borders.
