Abstract:	The U.S. Army Corps of Engineers, in coordination with the non-Federal sponsor, the Louisiana Department of Transportation and Development, propose construction to deepen the existing Mississippi River Ship Channel, Gulf to Baton Rouge, Louisiana, project. Currently, the project provides deep draft navigation along the lower portion of the Mississippi River from River Mile (RM) 233.8 Above Head of Passes (AHP) to the Gulf of Mexico ending at RM 22 Below Head of Passes (BHP). The MRSC allows for deep draft access to the Louisiana ports of Plaquemines, St. Bernard, New Orleans, South Louisiana, and Baton Rouge. The Supplemental Appropriations Act of 1985, Public Law 99-88 authorized the deepening of the existing channel from its depth, at the time, of 40 feet (ft) to 55 ft in accordance with the Report of the Chief of Engineers dated April 9, 1983, SUBJECT: “Mississippi River Ship Channel, Gulf to Baton Rouge, Louisiana.” Construction of the channel was initially planned in three phases. Among other things, the first phase deepened the channel to 45 ft from the Gulf of Mexico beginning at RM 22 BHP to Donaldsonville, LA, and the second phase deepened the channel to 45 ft from Donaldsonville, LA to RM 232.4 AHP. The reach from RM 232.4 to 233.8 AHP was not deepened. The third phase planned to deepen the length of the entire project to 55 ft. At the time of this report, the third phase has not been constructed and it is proposed in this report that full implementation of the project to a depth of 55 ft be addressed in phases beyond the third phase of construction for the project.
