Lower Mississippi Valley Division New Orleans District 29 JAN 1992 Channels: Ju Channel, 36 feet deep by 500 feet wide from Inner Harbor Eased Entrance Channel widens gradually from 500 feet at Locks: PHYSICAL DATA New Lock, 110 feet wide by 40 feet deep by 1,200 feet long JUSTIFICATION: New Orleans is the gateway to the great system of inland waterways of the central valley of the nation. Adequate outlets to the Gulf of Mexico are essential to provide economical transportation to this area. The project as large stage fluctuations as is the river. provides an additional outlet to the Gulf that is shorter than the Mississippi River route and one which is not subject to The improvement provides a tidewater outlet and harbor sufficiently spacious for dispersion of docks and cargo-handling facilities, thus permitting flexible operations of the inland and seagoing commerce which is utilizing the river, the tidewater canal, and the Gulf Intracoastal Waterway. The project provides savings in sailing time and ship turnaround time, reduction in navigation hazards, and relief from congestion. p qab The existing Inner Harbor Navigation Canal Lock passes barge traffic between the Mississippi River and the Gulf Intracoastal Waterway at New Orleans and is a vital link in the Gulf Intracoastal Waterway system. The lock also is the connecting link for ship traffic between the Mississippi River-Gulf Outlet and the Mississippi River at New Orleans. The existing lock has through 1990 averaged about 205 per year. a maximum practical capacity for barge traffic of approximately 30,000,000 tons. The number of ships locked from 1970 ship traffic. This is a reduction in ship lockages since 1961, and is due in part to the development of the Mississippi River-Gulf Outlet channel and the inadequacy of the Inner Harbor Navigation Canal Lock for Studies indicate that, with a new lock, barge traffic would generally be expected to increase to about benefits are as follows: 45,000,000 tons by 2035 and that the number of ship lockages by 2035 would be approximately 1,800.
