The following maps show the locations of proposed river training structures. These designs are preliminary and are subject to change. The purpose of these proposed structures is to reduce dredging and to stabilize the navigation channel in an environmentally sensitive, cost-effective manner. These engineered plans will be used to develop detailed drawings and specifications. They have not yet been advertised for construction and are not in any current contracts. Review of these plans by the Corps, U.S. Fish and Wildlife Service, state agencies, and other stakeholders is ongoing.
