Work is moving fast along the Mississippi River as crews continue building a major flood protection system in south Louisiana. The latest activity near Garyville shows clear progress on a project designed to protect thousands of residents from storm surge.
Work Underway Near Garyville
Construction crews are currently active near Garyville along the east bank of the Mississippi River.
This work is part of the West Shore Lake Pontchartrain Project, which aims to reduce storm surge risk for nearby communities.
At Site 109, workers are installing articulated concrete block mattresses and pouring strong concrete slabs to stabilise the area and support future floodwalls.
What the Project Is About
The project is being managed by the U.S. Army Corps of Engineers.
Its goal is to provide what is called “100-year storm protection,” meaning it is designed to protect against storms that have a 1% chance of happening in any given year.
The system will help safeguard areas in:
- St. Charles Parish
- St. John the Baptist Parish
- St. James Parish
Key Construction Features
The section known as WSLP-109 covers about one mile and includes both levees and a floodwall. It also features a special pipeline crossing structure.
Crews are currently focusing on two major tasks:
- Pouring concrete slabs that act as a strong base for floodwalls
- Placing articulated concrete mattresses to protect riverbanks
These steps are important for making sure the structure remains stable during strong currents and storms.
How Concrete Mattresses Help
Articulated concrete mattresses are flexible layers made of connected concrete blocks. They are placed along riverbanks to prevent erosion.
They work by slowing down water flow near the surface, which helps:
- Reduce soil erosion
- Protect slopes and infrastructure
- Allow sediment to settle and strengthen the bank
This makes them a key part of river protection projects.
Scale and Investment of the Project
The entire West Shore system is massive. It stretches about 23 miles and includes:
- Around 22 miles of levees
- About 1 mile of floodwall
So far, construction contracts worth nearly $445 million have been issued for different parts of the project.
What Residents Can Expect
Local officials say construction will continue in phases. Residents living near the river can expect ongoing activity as crews complete different sections, including drainage systems and pump stations.
Updates are being shared regularly by parish authorities and project agencies to keep the public informed.
