Mobile Harbor GRR, Design and Construction

In June 2014, the Alabama State Port Authority (ASPA) submitted a request to the U.S. Army Corps of Engineers to consider increasing the depth and width of the Mobile Harbor Channel.  Specifically, the request asked the Corps of Engineers to investigate the feasibility of taking the channel to authorized dimensions under Section 201 of the 1986 Water Resources Development Act (WRDA). 

Under the 1986 WRDA, the authorized dimensions for the majority of the channel were set at 55 ft. deep and 550 ft. wide.  The current dimensions of the majority of the channel are 45 ft. deep and 400 ft. wide.

The General Reevaluation Report (GRR) study began in late 2015 as a four-year, $7.8 million effort cost-shared with the ASPA.  The results of the study were documented in a GRR and released to the public in July 2019.  The recommendations provided in the study were approved by Major General Diana Holland, Commanding General of the U.S. Army Corps of Engineers, South Atlantic Division, and a Record of Decision was signed on September 6, 2019.

Mobile Harbor, Alabama, Project Phase 1 Deepening and Widening is currently under design, with an anticipated construction award date in the fall of 2020.  The first construction phase will consist of deepening in the southernmost portion of the bar (entrance) channel.  Construction for the entire project is anticipated to occur over six construction phases, targeting project completion circa March 2025.  Plans, Specifications, and other documentation associated with each construction phase will be added to the "Document Library" link on this page, and as they become available.
