Overview
The Mississippi River–Gulf Outlet Canal (abbreviated as MRGO or MR-GO) is a 76 mi (122 km) channel constructed by the United States Army Corps of Engineers at the direction of Congress in the mid-20th century that provided a shorter route between the Gulf of Mexico and New Orleans' inner harbor Industrial Canal via the Intracoastal Waterway. In 2005, the MRGO channeled Hurricane K…
History
Conceptually, the MRGO was first envisioned early in the 20th century as a way to provide shipping with a shorter route to the Gulf of Mexico. The Port of New Orleans felt increasingly disadvantaged by the length of time oceangoing vessels needed to navigate the twists and turns of the Mississippi River from the Gulf to the port's wharfs, versus the much closer proximity to open water offered by its emerging competitors. The modern Port of Houston, in particular, came into …
MRGO's operational performance
With the completion of MRGO in 1965, the Port of New Orleans advanced a plan to largely abandon its wharfs along the Mississippi River and relocate its activities to the inner harbor created by the Industrial Canal, the Intracoastal Waterway, and the MRGO. This vast project, termed Centroport U.S.A., never secured sufficient funding and was quietly jettisoned by the port in the mid-19…
Role in Hurricane Katrina disaster
Levees along the MRGO and the Intracoastal Waterway were breached in approximately 20 places, directly flooding most of St. Bernard Parish and New Orleans East. Storm surge from the MRGO is also a leading suspect in the three breaches of floodwalls along the Industrial Canal.
Three months before Katrina, Hassan Mashriqui, a storm surge expert at Louisi…
Closure
In May 2007 the Corps of Engineers announced it would close the MRGO to all traffic and would build an earthen dam across the MRGO in alignment with the natural ridge paralleling Bayou La Loutre. The Bayou La Loutre ridge siting was selected to complement future wetland restoration efforts, as the natural ridge could regain its historic function of sheltering the marsh and swamp behind fr…
Surge Barrier
Closer to New Orleans, a robust 1.8 mile surge barrier costing more than $1 billion was constructed. The surge barrier closed the narrow end of the "funnel" described by the convergence of the levees bounding the northern edge of the Intracoastal Waterway and the southern edge of the MRGO, preventing future storm surges from penetrating into the inner harbor of the Industrial Canal and Intracoastal Waterway. Two gates were built, one at Bayou Bienvenue and another acr…
